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.

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.

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).

- 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).

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.

Currently two tests fail (the approx 1.e-38 in single and double precision).
Need still to add tests for ASCII->internal conversion.

to configure to enable profiling and enable -Werror. Make changes to ensure
everything builds with all additional warnings and -Werror enabled. Most of
these changes consist of adding "const" modifiers for functions that get
constant literal strings.

conversion functions. For accuracy, change from 64-bit to 80-bit internal
mantissa. Modify tests to match new internal format.
TODO: Denormalized numbers, and write more tests!
svn path=/trunk/yasm/; revision=251
Interface changed slightly (only affects symrec.c right now). Tests committed
to check a single case (pi) with all three size conversion functions.
Still need to write to/from ASCII string functions (the hard part).
