Modularize errwarn. gettext()-ize in errwarn, not in every module, eliminating
libintl dependency in modules.
Also standardize initialize() and cleanup() functions.
Move replace_extension() from file.c to main.c.
Clean up some extern variable declarations in various places (particularly
nasm-compatible parser).

Dynamically load all modules (preloading some of the default ones).
Start reducing global variables for cleaner module separation.
Add rudimentary debug format module interface and "null" debug format.

Get rid of expr_xform_neg_tree(), integrating its functionality into
expr_level_tree(). This fixes negative equ's and probably other issues.
This also makes expr_simplify() a macro pointing to expr_level_tree().

Fix COFF_SET_VMA output (needed to add section start address to addend).

Run test input files through standard input instead of as input files to avoid
pathname changing issues when builddir != srcdir (previous workaround worked
for text files, but for more complex objfmts such as coff that embed the source

Make output endian-tolerant by making intnum and floatnum output functions for

file functions to use bits instead of byte/short/long, and create both little

Undo part of the tools/re2c flattening. Specifying a re2c_CFLAGS causes
automake to automatically prepend re2c- to all generated object files,
eliminating the main.o conflict. Also, it prevents extended compilation flags
from applying to the re2c build.
In Makefile.am, also allow automake to automatically include the autoconf
conditionally-included files strsep and mergesort.

Make test scripts more portable by detecting echo line-ending features, using
fewer options for sed, and using a perl script for hexdump. As a side effect,
hexdumps are more accurate (the hexdump util put * for as many multiples as
were output, whereas the perl script outputs a line for every byte, no matter
what).

Completely revamp how label resolution is done (part of Bug#6). Now calculates
/distances/ between bytecodes in a section using bc_calc_dist() functions (a
"typical" one is provided for most occasions). expr_expand_labelequ() is gone,
as its functionality is integrated into expr_simplify(). Currently these
changes break most bin objfmt output, as it doesn't know how to resolve
absolute labels yet. Also, very preliminary expr support for :, SEG, and WRT
operators has been added (part of Bug#2). Several other minor bug fixes.
