The directives code is already trying to do a bit more unified error
handling, so give ourselves a bit richer interface. At this point,
the conversion was pretty automatic so we probably return DIRR_OK
instead of DIRR_ERROR in a fair number of places, but that's okay.

Move directive processing to its own file, and move nasmlib/error.c to
asm/error.c (it was not used by the disassembler); remove some extern
declarations from .c files, and do some general code cleanups.

Make the arguments to add_sectname() constant. There are definitely
more things about this that ought to be cleaned up, including not
relying on magic offsets for the section numbers, but this is a
trivial cleanup that really needed to be done anyway.

If we get an output type we don't know how to handle, do a panic()
rather than a compile-time error; this will be necessary in the short
time pending a change to the backend interface.

stabs is the default debug format and GNU gold dies with an assertion

df_dwarf and df_stabs were orphans of the elf32/64 merge; clean up.

Make the source code easier to understand and keep track of by
organizing it into subdirectories depending on the function.

There is a bunch of common code here so merge them all into one file.
Unmergable parts are wrapped with is_elf() helpers.

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.)

If someone specifies "section align" without =value, error out.

Elf align section attribute requires syntax "align=value",
but in case if '=' is missed we pass nil pointer into
atoi function which cause libc to crash.

Merge elfcommon.h, elf32.h, elf64.h into
single elf.h -- we do support both elf32
and elf64 anyway. Let put them into common
place.

Add new copyright headers to the new output modules. As far as I
know, the only module which we still don't have a green light to
release under 2-BSD is outmacho.

Move backend-specific code into the output/ directory, and make the
null debugging backend a separate file (it certainly isn't needed for
ndisasm...)

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.

Add something approaching real ELF header files.
Begin merging the common ELF code, beginning with the section name
detection.
Drop automatic generation of .comment section, and in particular the
treatment of .common as a special section (if we decide generating
.comment is still a good idea, we should just do it as a macro.)
Augment the list of known sections, and make it table-driven.
