Fix some nits found by lclint. Still something weird going on with list2 in
mergesort(), according to lclint, but I haven't figured out if it's real or
not.

Start framework for separating architecture-dependent functions and data
structures from the rest of the assembler. We're not trying to write GAS
here (yet :), but doing this will make large parts of the codebase a lot
clearer.

Add coretype.h, make util.h do a lot more, use util.h to simplify include
sections of C files. Also remove IdPath from top comment in files where
RCSID() is used. Move RCSID() to immediately after util.h include.

bytecode_print(): Change how NULL values are output for imm and multiple.
bytecode_parser_finalize_insn(): Add some preliminary imm handling. Handle
shift_op special-casing (,1 hack).

Optimize expression building a bit in expr_new() by eliminating IDENT's here.
This saves a lot of extra unnecessary recursions when the expr gets to the
simplification stage.

Add option for malloc debugging using dmalloc library (http://dmalloc.com/).
Remove unnecessary stdlib includes (because we use xmalloc instead of malloc).

*COMPLETELY* rewrite most of expression handling.
Features:
- More complex memory expressions like [bx-(bx-di)] are now calculated through
as valid.
- Much better simplification.
Internal changes:
- More flexible n-way tree (rather than old binary-only).
- Many new functions to simplify and deal with very complex expressions.

Allow both signed and unsigned interpretations for get_int and check_size.
Change argument order on get_int and check_size to better match other
functions (intnum * first arg).

Add parsing of memory expressions. Currently adds a lot of duplication for
the expressions in the yacc code, but I don't see an easier way right now.
Also, no validity checking is done.

Add expr_contains_float() and symrec_get_equ() functions. These are the first
of many functions like this which will be needed for advanced validity checking
in the finalization of the parser stage.
Fix yacc grammar to not use the (incorrect) expr_no_fltstr, and change memexp
to memexpr and its handling to prepare for memory expressions.

Clarify and fix some usages of valid/need flags for modrm and sib bytes.
In bytecode_print(), check for NULL ea displacement and print out modrm and
sib bytes in octal (because it's easier to read the 2/3/3 format in octal).

Fix LOTS of little nits. Primary changes:
- New intnum module to replace using just unsigned long (for >32 bit values).
Read values using BitVector instead of strtoul().
- Brought both floatnum and intnum into expr (still need to integrate calc for
floatnum).
- Add traversal function to ternary tree (for use by symrec_foreach).
- Change floatnum output interface from single/double/extended to byte size.
- Try to make floatnum/intnum interfaces very similar. Still needs work.
- Add/fix *_print functions, including interating ones for sections/bytecodes.
- Fix handling of $ and $$. Both now are properly parsed and bytecode'd.
- Print out all sections and symbol table in main() in preparation for work
on "cleanup" functionality between parser and optimizer stages (really part
of the parser stage).

Make most data structures opaque, keeping internals truly internal and making the
overall structure much more modular.
The test files, which need access to the internals of the structures being
tested, now include the source file instead of the header file to gain access
to all internal formats and functions.

Add some (optional through configure) additional warning flags. Add options
