/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.

Bugzilla Bug#3. Not all instructions are parsed yet, so this is actually a
minor feature regression from the user side, but this commit lays the framework
for much easier additions of new assembler syntaxes and architectures. The
re2c tool is now used to generate the lexers, as it's much more flexibly
function-oriented than lex.
- nasm-bison.y is a repocopy+modify of nasm/bison.y.in.
- x86arch.h now includes all of x86-int.h

Changes to:
objfmt interface: added parameter to directive() for sections access.
section interface: moved start to be present for all section types.
basic optimizer: add section start to offset determination.
(much of the section start changes are due to the need to make sure offsets
don't end up being optimized into byte-sized offsets that can't be relocated).

- parser parse function (to pass to preproc initialize)

"index". This fixes some problems with assumptions made by various parts of
the code that are invalidated when the line number doesn't always increase (eg.
when the NASM %line directive is used).
Speed fixes are needed to the implementation of the line_* functions in
globals.c before this is finished.

yacc's default resolution gives correct results, and as the generated grammer
is smaller this way than specifically handling each prefix, we do it this way.

it didn't allow exprs with ID's before.

"ADD AX, byte 8" to generate the same code as NASM does (OT: this doesn't save
any space because the reg8x form needs a ModRM, but if it's what the user
wants, do it).

objfmt interface changed a lot due to this.
- New variables cur_objfmt and cur_parser that define what objfmt/parser are
active. They're set in main() by searching through the list of objfmts and
parsers. This necessitated libyasm.a to be listed twice in LDADD.

This is actually worthwhile; I found and fixed a few bugs/edge cases while
doing this.

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.
