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.)

Move version strings to a separate header, instead of needing to
include nasm.h in places where it probably really doesn't belong.

Avoid funnies with ordering of debug format selection by deferring
debug format search until after command line processing. Also permit
the -gformat syntax used by many C compilers.

Get rid of the completely pointless "debuginfo" parameter to
ofmt->cleanup(). Most backends completely ignore it, and the two that
care (obj, ieee) can simply test dfmt instead.
Also, dfmt is never NULL, so any test for a NULL dfmt is bogus.

Now when labels are properly concatenated in common code, there is no
reason for the debugging backend to need to be aware of local
symbols. We don't have to consider ..[^@] special symbols either, as
they are now filtered in labels.c.

labels.c now filter ..[^@] special symbols from the debug backend,
so we don't have to open-code that everywhere.
In the actual output format, don't treat ..@ symbols as special.

For local labels, starting with '.', the label name is concatenated with
the previous non-local label to produce a label that can be accessed from
elsewhere. This is the name we want to generate debug info for.
Labels starting with ".." are special and shouldn't be concatenated.

Move ofmt->current_dfmt into a separate global variable. This
should allow us to make ofmt readonly and removes some additional
gratuitious differences between backends.

We pass around a whole bunch of function pointers in arguments,
which then just get stashed in static variables. Clean this mess
up and in particular handle the error management in the preprocessor
using nasm_set_verror() which already exists.

Replace all instances of ERR_FATAL or ERR_PANIC with nasm_fatal or
nasm_panic so the compiler knows that these functions cannot return,
*and* we trigger abort() if we were to ever violate that constraint.

In order to make it more likely to compile cleanly with "C90 plus long

came from the first section, which is usually __TEXT,__text and

For 64 bits, a BRANCH reloc is sometimes needed to fix up PIC
problems. Make a best effort at generating BRANCH relocs just as
we make a best effort at distinguishing GOTLOAD from GOT.
This needs to be replaced with information from the assembler to
the backend.

The __TEXT segment in particular contains both code and data. The
most consistent thing is to look only at the section name, and have
