Reverse how traverse functions do early termination (now, they terminate on
a non-zero func return and return the value func returned). Document the
changes in the header files.

Fix issue with how symrec's are handled when an expression is copied: old code
just assigned the pointer: but the symrec is deleted (if it's not in the symbol
table) when the expr is deleted. Thus, we need to create a copy of the symrec
instead of just reusing the same value if it's going to be deleted later. This
trickles down to objfmt to copy the objfmt-local data.

Enhance error/warning framework by allowing specific warnings to be disabled,
all warnings to be disabled, and warnings to be treated as errors, much in the

In optimize_bytecode(), calculate bc->offset *before* calling bc_calc_len().
This is because calc_len may want to know the current bytecode's offset (eg for
determining relative displacement length).

Add new bc_resolve() family, and rewrite calc_len to /just/ calculate the

labels).

Make resolve_label() take a symrec * instead of a section * and bytecode *.

Change from current file/line dual storage to a monotonically-increasing line
"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.

Allow overrides (a32/a16/rep/etc) to appear on their own line. The way this
is done in the grammer causes 1 shift/reduce and 1 reduce/reduce conflict, but
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.
