Some OMF toolchain can make use of file dependency information
embedded in the object files. As implemented here, we don't try to
absolutize the filenames, as that prevents moving around trees and is
OS-dependent.

1. One incorrect variable use(!)
2. One possibly uninitialized variable.

We already have abort-on-error memory allocation and I/O operations in
nasmlib, so use them for rdoff as well.
Delete long-since-obsolete rdoff Mkfiles directory.

[f]stat on Windows is messy: we need to use _stati64 for maximum
compatibility, but because there is a bunch of stuff wrapped in
macros, autoconf sometimes gets the wrong answers.

On Windows we need to use _stati64/_fstati64 in order to handle large
file sizes, but the handling was broken in the canned MSVC++
configuration. Clean it up and fix it.
This addresses BR 3392398.

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.

Apparently, at least on some OS/2 compilers, <sys/types.h> needs to be
included for off_t to be defined. This seems like a generically good
idea to include this header whenever it is available.
Remove reference to <types.h>. This was supposedly for MSVC, but
there is no actual evidence that it is useful beyond <sys/types.h>.

Instead of trying to do hacks in the Makefiles, define header files
for specific compilers if they can't use autoconf. Currently defined
for Microsoft Visual Studio, based on MSDN documentation. It is
currently untested.

A number of fairly common operations are invoked way too many times,
especially when using incbin. Drastically reduce the number of system
calls that need to be executed, and use memory mapping to reduce
unnecessary double buffering.
We could improve this further by leaving files open once used;
however, that might run into file count problems on some systems.
Still unclear is why we seem to invoke nasm_file_size() twice per pass
for incbin.

Move fseeko, ftello, and off_t definitions to nasmlib.h so that files
other than nasmlib/file.c can use them (already added to
asm/assemble.c).

Add wrappers to fopen(). The intent is to replace references to
FILE * with an internal structure which can also cache things like the
filename and, when needed, the full pathname and checksums.
Also, add the "m" flag if we are compiling for glibc, for speed.

This reverts commit 55e51d9534.
First of all, _chsize_s() *does* set errno, even though it returns the
same value. Second of all, all we look for is a zero return value
anyway, so there is no need for this wrapper.

_chsize_s(), but not _chsize(), actually *returns* errno rather than
setting errno; create a wrapper routine to make it match the other
nasm_ftruncate() varieties.

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.)
