It is possible on memory exhaustion that nasm_fatal() might cause
another allocation error, thus calling nasm_alloc_failed() again. If
we find us in nasm_alloc_failed() for a second time, try to get a
message out and then call abort().

Add a version of (v)asprintf(), which allocates a string on the
heap. Unlike the standard version of (v)asprintf(), we return the
pointer; if one wants the length of the string then one can simply use
the %n pattern.

The currently-unused strtbl was basically a slightly different version
of strlist, with the find and linearize capabilities. Merge these two
together by augmenting strlist to have the same capabilities.

1. The mkdep.pl program didn't handle excluded dependencies correctly,
causing it to error out due to config/config.h not existing.
2. NMAKE is sensitive to the order suffixes appear in .SUFFIXES,
causing it to try to use the builtin rule .c.exe instead of
.c.obj -> .obj.exe.
3. NMAKE doesn't handle the && operator between commands.
4. The !ifdef jungle around dependency generation was wrong.

Apparently OS/2 really wants \ as path separators, and that is really
the main target for OpenWatcom these days, so change the path
separator in this Makefile. For building on Linux we'd be better off
with a GNU Makefile anyway, but what is the point, really...

Get rid of remaining dependencies on FILENAME_MAX, which ought to have
been removed a long time ago.
Remove ofmt->filename(); all implementations pretty much do the same
thing and there is absolutely no reason to duplicate that
functionality all over the place.

Several output formats use "string tables", which is a collection of
null-terminated (C) strings which are referenced by a byte offset into
the string table. A single string can be referenced an arbitrary
number of times.
As this is quite simple to implement with a hash table, we do exactly
that.

Some debugging formats may need to be able to split paths into
directory name and filename, at least. This is kind of iffy, at least
across platforms, but that isn't really expected to be an issue in
practice... we hope.

The standard syntax for a phony target in Make is:
target: <dependencies>
.PHONY: target
... however, Watcom WMAKE seems to use
target: <dependencies> .SYMBOLIC
and furthermore, seems to *require* it. Therefore, remove the
"perlreq" target from the automatically distributed region and move it
into the specific region; it should not need to change anyway since
the PERLREQ list itself is still synced.
If it was only a matter of the .SYMBOLIC versus .PHONY token it would
be easy enough to change that in syncfiles.pl, but this syntax change
is big enough that it doesn't make enough sense to worry about.

Add a generic facility for generating perfect string hashes, where all
that is needed is an enum and a string table. The existing mechanism
using a custom Perl script wrapped around a module continues to be
available for any use case where this particular approach isn't
sophisticated enough.
Much of this patch comes from renaming "enum directives" to "enum
directive" as a result of the string hash generator expecting a set of
uniform naming conventions.

There is no fundamental reason for all objects that don't contain a
main() function to not be part of libnasm.a; this allows the linker to
do its job optimally, especially in the presence of debugging code
which may not be needed under normal conditions.
If we do end up with function name conflicts the library might have to
be split, but it would be better to simply avoid that case.
