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.

- 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.

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.

properly (bug #8). Framework added for portable floating point support (bug
#7). Lots of functions still not finished in this commit.

of just one at a time. This is the groundwork for printing undefined symbol
messages, which can't be determined until after parsing has been completed
(and should be in the same line order with the other errors).

Cleaned up function naming too.
Removed locallabel_base from global.h, moving it into the parser-specific code.
Made sym_table private to symrec.c.

Also try to fix the warnings on the GNU C Library.
Still a lot of work and testing to be done here, but making progress.

effaddr * instead of an effaddr to decrease size of bytecode. Changed parser
to use effaddr * as well. Finally fixed issue with ONE by adding flag to
bytecode.data.insn and utilizing spare bytes of the opcode. Hackish, but
works.

asking the objfmt module. Add some utility functions for both bytecode
and section to better modularize their data structure usage and common
code. Rename doparse to do_parse to be consistent in naming.
