- \\ in high-level macro arguments

Currently, \\ is expanded in two situations:

1) macro and string definition (roff.c setstrn())

2) macro argument parsing (mandoc.c mandoc_getarg())

For user defined macros, the second happens in time because of ROFF_REPARSE.

But for standard high-level macros, it only happens after entering the

high level parsers, which is too late because the code doesn't get

back to roff.c roff_res() from that point. Because this requires

distinguishing requests, user-defined macros and standard macros

on the roff_res() level, it is hard to solve without the parser reorg.

- \\ is now implemented correctly

* when defining strings and macros using .ds and .de

* when parsing roff(7) and man(7) macro arguments

It does not yet work in mdoc(7) macro arguments

because libmdoc does not yet use mandoc_getarg().

Also check what happens in plain text, it must be identical to \e.

- .Bd -centered implies -filled, not -unfilled, which is not

easy to implement; it requires code similar to .ce, which

we don't have either.

Several areas can be cleaned up to make mandoc even faster. These are

- improve hashing mechanism for macros (quite important: performance)

Line 553 Several areas can be cleaned up to make mandoc even fa

Line 583 Several areas can be cleaned up to make mandoc even fa

- the PDF file is HUGE: this can be reduced by using relative offsets

parse, create a read-only version the first time and copy it
