322bee0aac Additional listing options, improve help output, fix macro limits
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.

d6e817751e listing: add -L option for additional listing info
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.

0d4d431a01 Merge empty reservations from TIMES; add counts in listings
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.

8960e1bc83 Remove #includes already provided by "compiler.h"
"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.

374312cde4 strlist, warnings: improve strlist, buffer warnings until error
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.

e2f5edbb3a error: new flag ERR_HERE
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

it more useful.

a77692b34d New backend interface - assembler internals #1
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.)
