Make the NSIS output automatically select the output architecture to
generate the proper filename and, much more importantly, set up the
proper default install directory.
This requires Perl as well as makensis to be present in order to make
an installer, but that doesn't really seem like a too onerous of a
requirement (NSIS being the big external dependency here.)

Most preprocessor warnings are ERR_PASS1, but we want to see them in
the listing file too. If we make it to the code-generation pass,
ignore ERR_PASS* for the purpose of emitting warnings to the list
file.
While we are at it, allow ERR_DEBUG to specify ERR_PASS* too.

Additional places where we can change ERR_PANIC and ERR_FATAL to
nasm_panic and nasm_fatal. Note that nasm_panic and nasm_fatal should
*aways* be expected to be fatal; they should never be used in a
suppressed context. It is critical that we verify that this doesn't
break anything.

We pass around a whole bunch of function pointers in arguments,
which then just get stashed in static variables. Clean this mess
up and in particular handle the error management in the preprocessor
using nasm_set_verror() which already exists.

Replace all instances of ERR_FATAL or ERR_PANIC with nasm_fatal or
nasm_panic so the compiler knows that these functions cannot return,
*and* we trigger abort() if we were to ever violate that constraint.

Just like nasm_panic(), nasm_fatal() tells the compiler that

autoconf's handling of --without and --disable are a bit
counterintuitive: instead of calling the "not given" branch of the
conditional, they instead call the "given" part of the conditional
with an argument of "no". Make --disable-werror work as expected.

In order to make it more likely to compile cleanly with "C90 plus long
long" style compilers, remove existing constructs (mostly commas at
the end of enums) that aren't compliant.
Ironically enough this was most likely an unintentional omission in

For 64 bits, a BRANCH reloc is sometimes needed to fix up PIC

we make a best effort at distinguishing GOTLOAD from GOT.

Right now, we don't check the return value from nasm_realpath();
furthermore doing so and failing is probably not the ideal behavior.
If we can't get the full canonical path, then punt and just return
nasm_strdup() of the known path name; better than nothing.

If we specify .rodata as opposed to the explicit __DATA,__const, and
we end up with no relocations, change it to __TEXT,__const per the
Mach-O ABI. However, it is generally better for the programmer to
explicitly specify the items that should go into __TEXT,__const as
otherwise a single relocatable item will force the whole thing into
__DATA.
