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.

Move memory-mapping functions from file.c into a separate mmap.c.
This will be cleaner especially once (if) we end up doing a Windows
implementation, which is likely to look entirely different.

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.

nasmlib.c had basically turned into a garbage bin of various functions
with very little in common. Break it up into logical components for
isolation and manageability.

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.

* Added missing rules for creating a library out of LIBOBJ
and using it when linking.
* Updated the clean rule and PRELREQ list.
* Always build with debug info as it ends up in external PDB files
anyway and doesn't really impact binary size.
* Added /RELEASE to the LDFLAGS so the linker checksums the headers and
the binary can be signed.

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
break the build anyway.)

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.

nasmlib.[ch] desperately need to be broken up into smaller chunks.
Break file I/O related functions out into file.c, so at least we can

Codeview is a debug format for win32/win64 PE/COFF files. It adds two sections,
.debug$S (symbols) and .debug$T (types), to the generated object file. These
sections are then used by the linker to generate a PDB file which can be used
by various debuggers (WinDbg, Visual Studio, etc).
