Shrink -Tps output by more than 50%
by using PostScript as a programming language.
* Define and use one PostScript procedure to select each font.
* Define and use procedures combining "use" and "show".
* In one of these, reuse the current row if it did not change.
Most ideas and most coding by espie@, tweaked by me.

Print a human-readable media name in the %%DocumentMedia DSC comment

automatically select the paper of the best matching PageSize.

Many thanks to Mike Williams <obsd1 at eandem dot co dot uk>
for teaching me about the relevant features of PostScript and DSC
and for suggesting what to put into the first %%DocumentMedia argument.

The page footer line (psmarg) is created in ps_begin(), and the
last call writing to it is always ps_endline(), which ends with
ps_pclose(), which prints "ET" (end text).

Consequently, do not print another instance of "ET" in ps_closepage()
after the footer line and before the "endstream" for the page.

Fixing a PDF syntax error found while investigating the bug report
from Jan Stary that also resulted in the previous commit.

Major character table cleanup:
* Use ohash(3) rather than a hand-rolled hash table.
* Make the character table static in the chars.c module:
There is no need to pass a pointer around, we most certainly
never want to use two different character tables concurrently.
* No need to keep the characters in a separate file chars.in;
that merely encourages downstream porters to mess with them.
* Sort the characters to agree with the mandoc_chars(7) manual page.
* Specify Unicode codepoints in hex, not decimal (that's the detail
that originally triggered this patch).
No functional change, minus 100 LOC, and i don't see a performance change.

Finally use __progname, err(3) and warn(3).

It's a bad idea to boycott good interfaces merely because standards
committees ignore them.  Instead, let's provide compatibility modules

them.  The compat module has an UCB Copyright (c) 1993...

Rounding rules for horizontal scaling widths are more complicated.
There is a first rounding to basic units on the input side.
After that, rounding rules differ between requests and macros.
Requests round to the nearest possible character position.
Macros round to the next character position to the left.

Implement that by changing the return value of term_hspan()
to basic units and leaving the second scaling and rounding stage
to the formatters instead of doing it in the terminal handler.

Improves for example argtable2(3).

Prevent negative arguments to the .ll request from causing integer
underflow.  Found while preparing an audit of termp.rmargin.

Overflow can also happen, but i see no sane way to deal with it,
so just let it happen.  It doesn't happen for any sane input anyway,
groff behaviour is undefined, and the resulting values are legal,
even though they are useless.

Make the character table available to libroff so it can check the
validity of character escape names and warn about unknown ones.
This requires mchars_spec2cp() to report unknown names again.
Fortunately, that doesn't require changing the calling code because
according to groff, invalid character escapes should not produce
output anyway, and now that we warn about them, that's fine.

Support overstriking by backspace in PostScript and PDF output.
Of course, this is only a minor improvement; it would be much better
to support non-ASCII characters in these output modes, but that
would require major changes that i'm not going to work on right now.

The main reason for doing this is that it allows to get ASCII output
closer to groff.

When support for bold italic font was added to the parsers and to the
generic parts of the formatters some time ago, the PostScript- and
PDF-specific part of the formatters was neglected.

Now pascal@ reports that mandoc -Tps throws an assertion on perl(1),
apparently because that manual actually uses bold italic font.

So here is an overdue implementation of bold italic font support for
PostScript and PDF output.

Begin cleaning up scaling units.

Lastly, fix some completely-wrong documentation and note that we diverge
from troff w/r/t "u".

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.

Initial PDF shim over PS.  This produces working PDF output with -Tpdf.
It's currently missing the xref table, so you'll get a warning in most
PDF viewers).  It also produces lots of redundant output, which will go
away once I get a better handle on the PDF spec.  The code doesn't
really touch any existing functionality; it's a bunch of conditionals
atop the -Tps (term_ps.c) implementation.  I'm checking it in now to
have it exist and be auditable.  It needs clean-up, polish, and general
care (and xref!).

Initial chunks for variable-width fonts.  Pushes all width calculations

implemented in term.c, although stubs for width calculations are in
place.  From now on, offset, rmargin, and other layout variables are
abstract screen widths.  They will resolve to the the familiar values
for -Tascii but -Tps will eventually use points instead of chars.

Have the standard manpage header and footer print on every page of -Tps
output.  This is more tricky than you may think:  we can't just call the
header function out-of-state (i.e., before a flushln has occured)
because we'd clobber our current state.  Thus, we call at the beginning
and dump the output into an auxiliary buffer.

For the record, I don't think there's any other clean way to do this.
The only other Way That Works is to copy-aside *all* termp state, zero
it, and do the necessary headf/footf.  This is just as complex, as
memory needs to be alloc'd and free'd per margin.

Unfortunately, this prohibits page numbering (the margin is only printed
once), so I'll probably end up re-writing this down the line.
