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

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.

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.)

For consistency with ofmt/dfmt, change the listing structure
to "struct lfmt" and "lfmt" and move it to listing.h.

By default we setup @listname to '\0' and if has
not been specified in command line it is passed
in this form into list_init() which cause
| [cyrill@uranus nasm.git] ./nasm -felf64 t.asm
| nasm: error: unable to open listing file `'
So make a proper test here.

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.

Instead of completely useless sequential line numbers, emit line
numbers corresponding to the line numbers in the source code.

size is actually an uint64_t, and LLVM drops the abs() on the
principle that the uint64_t should always be positive. Make it
explicit that we are converting to a signed integer first, by using
abs((int)size) instead.

Add OUT_REL1ADR (one-byte relative address) and support for
OUT_ADDRESs with size == 1. Add support for it in
outbin and outdbg. *It still needs to be added to other backends*,
both the OUT_REL*ADR and OUT_ADDRESS codepaths need to be handled.

Instead of removing the list file on error, keep the list file and
include the errors in the list file. This makes it actually possible
to debug things that involve deep macro recursion, where the line
number is pretty much meaningless.

*To the best of my knowledge*, we now have authorization from everyone
who has significantly contributed to NASM in the past. As such,
change the license to the 2-clause BSD license.

Add copyright headers to the *.c/*.h files in the main directory. For
files where I'm sure enough that we have all the approvals, I have
given them the 2-BSD license, the others have been given the "LGPL for
now" license header. Most of them can probably be changed after
auditing.

Address data is always int64_t even if the size itself is smaller;
this was broken on bigendian hosts (still need testing!)
Create simple "write sized object" macros.
Don't combine type and size into a single argument; *every* backend
immediately breaks them apart, so it's really just a huge waste of
effort. Additionally, it avoids using short immediates in the
resulting code, which is a bad thing.
Both C and C++ have "bool", "true" and "false" in lower case; C
requires <stdbool.h> for this, in C++ it is an inherent type built
into the compiler. Use those instead of the old macros; emulate with
a simple typedef enum if unavailable.
Concentrate compiler dependencies to compiler.h; make sure compiler.h
is included first in every .c file (since some prototypes may depend
on the presence of feature request macros.)
Actually use the conditional inclusion of various functions (totally
broken in previous releases.)
