Use a separate node->tag attribute rather than abusing the node->string
attribute for the purpose.  No functional change intended.
The purpose is to make it possible to later attach tags to text nodes.

Support manual tagging of .Pp, .Bd, .D1, .Dl, .Bl, and .It.
In HTML output, improve the logic for writing inside permalinks:
skip them when there is no child content or when there is a risk
that the children might contain flow content.

Branch: MAIN
Changes since 1.71: +3 -1 lines
Diff to previous 1.71 (colored)

Fully support explicit tagging of .Sh and .Ss.
This fixes the offset of two lines in terminal output
and this improves HTML output by putting the id= attribute
and <a> element into the respective <h1> or <h2> element rather
than writing an additional <mark> element.

To that end, introduce node flags NODE_ID (to make the node a link
target, for example by writing an HTML id= attribute or by calling
tag_put()) and NODE_HREF (to make the node a link source, used only
in HTML output, used only to write an <a class="permalink"> element).

In particular:
* In the validator, generalize the concept of the "next node"
such that it also works before .Sh and .Ss.
* If the first argument of .Tg is empty, don't forget to complain
if there are additional arguments, which will be ignored.
* In the terminal formatter, support writing of explicit tags
for all kinds of nodes, not just for .Tg.
* In deroff(), allow nodes to have an explicit string representation
even when they aren't text nodes.  Use this for explicitly tagged
section headers.  Suprisingly, this is sufficient to make HTML
output work, without explicit code changes in the HTML formatter.
* In syntax tree output, display NODE_ID and NODE_HREF.

Changes since 1.70: +7 -3 lines
Diff to previous 1.70 (colored)

Introduce the concept of nodes that are semantically transparent:
they are skipped when looking for previous or following high-level
macros.  Examples include roff(7) .ft, .ll, and .ta, mdoc(7) .Sm
and .Tg, and man(7) .DT and .PD.  Use this concept for a variety
of improved decisions in various validators and formatters.

While here,
* remove a few const qualifiers on struct arguments that caused trouble;
* get rid of some more Yoda notation in the vicinity;
* and apply some other stylistic improvements in the vicinity.

I found this class of issues while considering .Tg patches from kn@.

Diff to previous 1.69 (colored)

Introduce a new mdoc(7) macro .Tg ("tag") to explicitly mark a place
as defining a term.  Please only use it when automatic tagging does
not work.  Manual page authors will not be required to add the new
macro; using it remains optional.  HTML output is still rudimentary
in this version and will be polished later.

Thanks to kn@ for reminding me that i have been considering since
BSDCan 2014 whether something like this might be useful.  Given
that possibilities of making automatic tagging better are running
out and there are still several situations where automatic tagging
cannot do the job, i think the time is now ripe.

Feedback and no objection from millert@; OK espie@ inoguchi@ kn@.

When the -S option is given to man(1) and the requested manual page
name is not found and the requested architecture is unknown, complain
about the architecture rather than about the manual page name:

$ man -S vax cpu
man: Unknown architecture "vax".
$ man -S sparc64 foobar
man: No entry for foobar in the manual.

Move parsing of the .nf and .fi (fill mode) requests from the man(7)
parser to the roff(7) parser.  As a side effect, .nf and .fi are
now also parsed in mdoc(7) input, though the mdoc(7) formatters
still ignore most of their effect.

Cleanup, no functional change:

The struct roff_man used to be a bad mixture of internal parser
state and public parsing results.  Move the public results to the
parsing result struct roff_meta, which is already public.  Move the
rest of struct roff_man to the parser-internal header roff_int.h.

Since the validators need access to the parser state, call them
from the top level parser during mparse_result() rather than from
the main programs, also reducing code duplication.

This keeps parser internal state out of thee main programs (five
in mandoc portable) and out of eight formatters.

Cleanup, no functional change:
Now that message handling is properly encapsulated,
remove struct mparse pointers from four structs (roff, roff_man,
tbl_node, eqn_node) and from the argument lists of five functions
(roff_alloc, roff_man_alloc, mandoc_getarg, tbl_alloc, eqn_alloc).
Except for being passed to the main program as an opaque object,
it now only occurs in read.c, as it should, and not across 15 files
like in the past.

Cleanup, no functional change:

mandoc.h, into a new header mandoc_parse.h, for use in the main
program and in the main parser only.
Move enum mandoc_os into roff.h because struct roff_man is the
place where it is stored.
This allows removal of mandoc.h from seven files in low-level
parsers and in formatters.

Split -Wstyle into -Wstyle and the even lower -Wbase, and add
-Wopenbsd and -Wnetbsd to check conventions for the base system of
a specific operating system.  Mark operating system specific messages
with "(OpenBSD)" at the end.

Please use just "-Tlint" to check base system manuals (defaulting
to -Wall, which is now -Wbase), but prefer "-Tlint -Wstyle" for the
manuals of portable software projects you maintain that are not
part of OpenBSD base, to avoid bogus recommendations about base
system conventions that do not apply.

Issue originally reported by semarie@, solution using
an idea from tedu@, discussed with jmc@ and jca@.

Naive implementation of the roff(7) .po (page offset) request.

not be sophisticated enough if people call .po inside indentation-changing

Implement the roff(7) .rn (rename macro or string) request.
Renaming a user-defined macro is very simple: just copy
the definition to the new name and delete the old name.
Renaming high-level macros is a bit tricky: use a dedicated
key-value-table, with non-standard names as keys and standard
names as values.  When a macro is found that is not user-defined,
look it up in the "renamed" table and translate it back to the
standard name before passing it on to the high-level parsers.

In private header files, __BEGIN_DECLS and __END_DECLS are pointless.
Because these work slightly differently on different systems,
they are becoming a maintenance burden in the portable version,
so delete them.

Besides, one of the chief design goals of the mandoc toolbox is to
make sure that nothing related to documentation requires C++.
Consequently, linking mandoc against any kind of C++ program would
defeat the purpose and is not supported.
I don't understand why kristaps@ added them in the first place.

Very tricky diff to fix macro interpretation and spacing around tabs
in .Bl -column; it took me more than a day to get this right.
Triggered by a loosely related bug report from tim@.

The lesson for you is:  Use .Ta macros in .Bl -column, avoid tabs,
or you are in for surprises:  The last word before a tab is not
interpreted as a macro (unless there is a blank in between), the
first word after a tab isn't either (unless there is a blank in
between), and a blank after a tab causes a leading blank in the
respective output cell.  Yes, "blank", "tab", "blank tab" and "tab
blank" all have different semantics; if you write code relying on
that, good luck maintaining it afterwards...

Step 1 of restructuring: libmandoc.h.  Move all compiler-set-specific
stuff into libmandoc.h, including old mdoc.h/man.h/roff.h functions now
used by read.c.  The motivation behind this is to tighten the
relationship between the underlying compilers while keeping parse data
hidden from general callers (e.g., main.c).

While here, also move register values from mandoc.h into libmandoc.h as
noted by schwarze@.  See above for explanation.

Consolidate messages.  Have all parse-time messages (in libmdoc,
libroff, etc., etc.) route into mandoc_msg() and mandoc_vmsg(), for the
time being in libmandoc.h.  This requires struct mparse to be passed
into the allocation routines instead of mandocmsg and a void pointer.
Then, move some of the functionality of the old mmsg() into read.c's
mparse_mmsg() (check against wlevel and setting of file_status) and use
main.c's mmsg() as simply a printing tool.

Allow EQN data to be pushed down into libmdoc via mdoc_addeqn().  Only
the adding itself is implemented; equation data is not yet shown.

Add initial EQN support to mandoc.  This parses, then throws away, data
between EQ and EN roff blocks.  EQN is different from TBL in that data
after .EQ is unilaterally considered an equation until an .EN.  Thus,
there's no need to jump through hoops in having table spans and so on.
This is ONLY the parse code framework in libroff.  EQN is not yet passed
into the backends.

Initial tbl framework.  Parse point is in libroff, which keeps a
reference to a current tbl parse and routes ALL text into the tbl parse
after stripping reserved words and making block-level pre-processing
(e.g., `ig').  This is consistent with an analysis of embedded `TS/TE'
in manuals with sprinkled -mdoc, roff, and -man macros.

Fact of a parse is exposed to main.c by a return value (ROFF_TBL), which
will trigger main.c to add a foreign parsed body to the -mdoc or -man
parse stream.  This interface isn't in yet, but will follow the
parse-text functions in both libraries.  I put this login in main.c
because I don't want libroff calling directly into libmdoc or libman.

As a consequence, a parsed row can be pushed directly into any -mdoc or
-man context (put a `Bd -literal -offset indent' into a `TE/TS' block to
see why this is necessary).  It will then absorb formatting cues in the
front-ends.

A note on naming.  I decided on libroff.h instead of tbl.h because this
is purely within the roff layer.  Separate tbl implementations will
need, then, to interface with libroff.  This is "how it should be"
because tbl is tightly linked with roff in terms of `ds' and other
formatting macros, as well as, of course, special characters and other
roffisms.

Merge restructuring of main.c code.  This provided by schwarze@ and inspected
carefully by joerg@.  Merge roff.h header for compilation's sake (this is not
yet implemented in roff.c.).

THIS IS A BUGGY CHECK-IN.  The manual type is erroneously kept between runs
of the compiler.  This is a known bug.

Implement a simple, consistent user interface for error handling.
We now have sufficient practical experience to know what we want,
so this is intended to be final:
- provide -Wlevel (warning, error or fatal) to select what you care about
- provide -Wstop to stop after parsing a file with warnings you care about
- provide consistent exit status codes for those warnings you care about
- fully document what warnings, errors and fatal errors mean
- remove all other cruft from the user interface, less is more:
- remove all -f knobs along with the whole -f option
- remove the old -Werror because calling warnings "fatal" is silly
- always finish parsing each file, unless fatal errors prevent that
This commit also includes a couple of related simplifications behind
the scenes regarding error handling.
Feedback and OK  kristaps@;  Joerg Sonnenberger (NetBSD) and
Sascha Wildner (DragonFly BSD) agree with the general direction.

Downstream maintainers: this removes UGLY!  I don't want diverging
functionality and UGLY works quite well thanks to schwarze@'s careful
attention.

This also backs out function-prototype changes for struct regset,
instead stuffing a pointer to the regset directly into struct
mdoc/man/roff.

First step of adding register support.  This is inspired by a significant
patch by schwarze@.  This commit adds support to libroff parsing `nr'
into register set defined in regs.h.  This will propogate into libmdoc
and libman in later commits.

libroff now is aware of which sub-nodes should be interpreted even in a
conditional-negative context so as to preserve structural integrity.
Initial "rules" (deny/allow) are now inherited for future work in
evaluating conditionals.

Lint-fix noted by Joerg.

Added regression tests for zany constructs.

Allow roff_parseln() to be re-run.
Allow roff_parseln() to manipulate the line buffer offset.  This is used
in situations like `.ie n .TH FOO 1' or `.ie n .ie n', where the line
buffer offset is recalculated then the roff parser re-run.
Fix mdoc_parseln() and man_parseln() to accept the initial line offset.
WARNING: backed-out ALL roff macros whilst accomodating for how roff
handles multi-line conditionals (in short, re-running the parser).
