afa06137fa Hash even backend-specific directives, unify null functions
Hash all directives, even the ones that are backend-specific,
and instead pass the backend an already-parsed directive number.

Furthermore, unify null functions across various backends.

31b707bef0 Move backend-specific code to output/; break out null debug stuff
Move backend-specific code into the output/ directory, and make the
null debugging backend a separate file (it certainly isn't needed for
ndisasm...)

1acf6ba822 Handle the new ELF headers in the dependency generation
The dependency machinery relies on properly rooted includes, so give
it to them... the path syntax munging machinery in the dependency
script handles it from a Makefile syntax perspective, and then we can
hope that C compilers are smart enough to deal with forward-slash
paths even when that is not the native syntax.

1fee7d2d23 ELF: use rbtree for symbol searches
Linear searches are evil, so use an llrbtree to search for symbols by
offset.  This doesn't change the preexisting behaviour that we only
look for global symbols.

4b9358928b Move all version strings to a single compilation unit (ver.c)
Move all the version strings to a single compilation unit, ver.c; this

e8873121aa rbtree: drop the data pointer; instead rely on being embedded
Drop the data pointer, and instead assume the struct rbtree will be
embedded in a bigger data structure (to be extracted via
container_of()).

3e364fe274 Left-leaning red-black tree data structure
Implement library functions for "left-leaning red-black trees" with
uint64_t keys.  This is meant for looking up symbols by address in the
backends that need to do so, e.g. ELF.

A good question is if there is a better way to do this, that recovers
the original symbol, but that's a future issue.

d2456590fc preproc: add support for builtin include modules (%use)
Add a builtin equivalent to the %include directive called %use.
%use includes a standard macro file compiled into the binary; these
come from the macros/ directory in the source code.

The idea here is to be able to provide optional macro packages with
the distribution, without adding complex host filesystem dependencies.

compilation unit, since there really isn't any reason for it not to
be.

3720f7beae Generate a byte array instead of using strings for the byte codes
Generate a byte array instead of using C compiler strings for the byte
codes.  This has a few advantages:

- No need to special-case zero due to broken C compilers.
- Only insns.pl only ever reads the string, so we can invent our own
  syntax.
- Compaction.
- We can give it the proper, unsigned type.

9964558613 Fix the options when compiling under OpenWatcom
OpenWatcom needs different strings for compile and link target, so
using -bcl which uses the same string for both is just plain wrong.
This fixes that bit, but running nasm on test/floatx.asm (at least as
a DOS or a Win32 binary) crashes with a NULL pointer reference inside
the C library free() function.

c38c117188 Add Makefile for OpenWatcom (DOS, OS/2 or Win32 output)
Add a Makefile for OpenWatcom using WMAKE.  This is a horrible version
of Make, but since it's bundled with OpenWatcom it is probably better
to stick to it.  It has the nice property that it can produce DOS,
Win32 or OS/2 binaries.

This Makefile currently assumes that it is hosted on a system where
pathname separators are backslashes.  For cross-compiling using
OpenWatcom on a Linux system it is probably better to write a separate
Makefile using GNU make to invoke Watcom.
