Fix circular dependency on asm/warnings.c by factoring out
warnings.$(O) from the dependencies, and use a separate <file>.time
which "generate" the main source file as a "side effect", giving us a
null target.

The warning files are generated by a script, but the scripts is fast
enough run every time a C file is updated. To prevent having to
rebuild every file, however, make the generation script only actually
modify the file if it has changed.

config/unconfig.h really is no different than the other perlreq files,
so move it into the Makefile. This has the extra advantage that
config/unconfig.h no longer needs to be kept in the source repository.

Add warnings.src to PERLREQ. If this isn't done, warnings.src ends up
in the xdoc tarball rather than the release tarball, which means that
unless the user can "make warnings" manually (which requires Perl)
then they can't build the documentation.
As this only affects the documentation build, it probably does not
warrant a point release.
Add a few more extensions to the list of recognized binary extensions
for the purpose of generating a .zip file with DOS line ending
conventions.

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.

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.

Sometimes we really want to use an extended pathname for an include
file, for documentation purposes; e.g. "config/config.h". This makes
alldeps handle that case correctly (and also adds the config/
directory to directories scanned by alldeps).
It is unclear if this will work correctly if there are include files
with the same name in different directories, but we currently do not
have any case like that.

The old code for keeping track of source file name and line was
confused as hell about ownership of the strings, and it is pretty
clear we leaked that information all over the place.
Instead, use a hash table to keep a copy of each string as necessary,
and simply make references to a string pool that we keep until the end
of the assembly session.
This pool probably should be unified with the list of dependency
files, and so on, but that is for the development branch.
