1. Error messages would issue with the line number of %endrep.
2. Debug line information would ignore both macros and reps.
This is doubly wrong; macros are semantically equivalent to
inline functions, and it is expected that debuggers trace
into these functions.
These changes finishes the last parts of moving all responsibility for
the listing enable/disable into the preprocessor, so remove the
way over-complicated macro inhibit facility from the listing module
entirely.

<res ...> can get rather annoying when mixed in with data, as can
happen with the MASM-like db syntax. List shorter blocks (8 bytes or
less) as ?? instead; 8 bytes avoids line breaks for a single
statement.
This is probably more readable anyway...

Add the -Lw option to flush the list file after every line
output. This is handy for debugging if nasm hangs.

Encapsulate the list_options() encoding in an inline function. We only
ever compute a mask with a non-constant input in two places (command
line and pragma parsing), so a slightly more complex mapping is of no
consequence; thus map a-z, A-Z and 0-9 as being the most likely
characters we may want to use as options. Space is left for two more :)

Add a %pragma to set (or clear) listing options. It only takes effect
on the next assembly pass, however!

With the -Lp option, the listing generator gets invoked multiple times
in the same session. If we already have a list file open, call
list_cleanup() before reinitializing; otherwise we get stray output in
the updated file.

Merge TIMES in the nonfinal passes, there is no point in getting <len
...> an arbitrary number of times.
Actually print <len> (OUT_RAWDATA without a data pointer), not <res>
(OUT_RESERVE).
Dropping the zero-fill for the hex format made the listing more
manageable, but it also doesn't immediately look like hex, plus there
is now the -Ld option. Put an h after hex (shorter than leading 0x) to
make it obvious.

Additional listing options:
-Ld to display counts in decimal
-Lp to output a list file in every pass (to make sure one exists)
Clean up the help output and make it comprehensive. The -hf and -y
options are no longer necessary, although they are supported for
backwards compatiblity.
Fix macro-levels so it actually count descent levels; a new
macro-tokens limit introduced for the actual token limit.
Slightly simplify the limits code.

Add an -L option for additional listing information. Currently
supported is -Le, which emits each line after processing through the
preprocessor, and -Lm, which displays each single-line macro defined
or undefined.
NASM doesn't preserve the names of unused arguments, nor does it have
any technical reason to do so. Instead of adding complexity to save
them, make unnamed parameters official by specifying an empty string
in the argument list.
This has the additional advantage that () is now simply considered a
single empty argument, which means that NASM should now properly
handle things like:
%define myreg() eax
mov edx,myreg()
... similar to how the C preprocessor allows an empty macro argument
list which is distinct from a macro with no arguments whatsoever.

For constructs like TIMES xx RESB yy merge the TIMES and RESB and feed
a single reservation to the backend; this can (obviously) be
dramatically faster.
Add byte count in listings for <incbin> and repeat count to <rept>; to
make them more reasonable in length shorten to <bin ...> and <rep ...>
respectively, and don't require leading zeroes in bin/rep/res count.

"compiler.h" already includes a bunch of common include files. There
is absolutely no reason to duplicate them in individual files, and in
fact it robs us of central control of how these files are used.

Make strlist_free() take a pointer to a pointer, so we can set it to
NULL.
Buffer warnings on a strlist until we either get an error or we are in
pass 2. Hopefully this should let us get rid of a lot of the ERR_PASS*
bullshit, which far too often causes messages to get lost.
asm/labels.c contains one example of a warning that cannot be made
correct with a specific pass number.

ERR_HERE is used to mark messages of the form "... here" so that we
can emit sane output to the list file with filename and line number,
instead of a nonsensical "here" which could point almost anywhere.
This patch contains some changes from the one in the master branch to
make the code cleaner.

Make the internal handling of segment numbers just a little more

This provides the first pass of assembler internals for a new, richer,
backend interface. It also reduces the amount of data carried in
function parameters inside the assembler.
The new interface is in the form of a structure, which will contain
substantially more information that the previous interface. This will
allow things like ELF GOT32X and Mach-O X86_64_RELOC_BRANCH
relocations to be reliably emitted.
This provides the initial set of structures. Future additions should
include:
1. Pass down the base symbol, if any.
2. Segments should be a structure rather than a number, and the
horrible hack of adding one for a segment reference should be
removed (OUT_SEGMENT replaces it.)
