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.

Split lib/ into nasmlib/ (for nasm-specific functions) and stdlib/
(for replacements for C library functions which may be missing.)
Rename the ersatz inttypes.h to nasmint.h so we can use a simple test
in compiler.h instead of dealing with include path magic.
Remove tests in configure.in for ancient missing functions (which will

There is no reason to not use an archive manager to build our
executables. If there really are systems which don't have any kind of
archive manager, we can simply link all the objects.
This also drops any use of configure to detect library objects.
Instead just use HAVE_* and let the archive manager delete them.
A lot of additional functions could be declared library functions and
reorganized.

Make the NSIS output automatically select the output architecture to
generate the proper filename and, much more importantly, set up the
proper default install directory.
This requires Perl as well as makensis to be present in order to make
an installer, but that doesn't really seem like a too onerous of a
requirement (NSIS being the big external dependency here.)

Codeview is a debug format for win32/win64 PE/COFF files. It adds two sections,

sections are then used by the linker to generate a PDB file which can be used
by various debuggers (WinDbg, Visual Studio, etc).

Move the handling of "extra" macros (i.e. output format macros) into
the macros.pl mechanism. This allows us to change the format of the
internal macro store in the future - e.g. to a single byte store
without redundant pointers.
Also, stop using indicies into a long array when there is no good
reason to not just use different arrays.
Compress macros.c by representing macro directives with a single byte.
We can do this because we only use the ASCII character range inside
the standard macro files.
Note: we could save significant additional space by not having a
pointer array, and instead relying on the fact that we sweep
sequentially through the output array.
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.
"make alldeps" doesn't really like it when included files end in *.c.
Instead of renaming insnsb.c to insnsb.h, make it an actual
compilation unit, since there really isn't any reason for it not to
be.
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.
When using temporaries in macros, given them a unique prefix to avoid
namespace collisions when using one macro inside another.
Move the WSAA*() macros from outelf32/outelf64 to a separate header
file.
