b20bc733c9 asm/*: Move directive processing to its own file, refactor error handling
Move directive processing to its own file, and move nasmlib/error.c to
asm/error.c (it was not used by the disassembler); remove some extern
declarations from .c files, and do some general code cleanups.

09dff8b257 Remove casts in switch statements only meant to keep OpenWatcom happy
Remove casts in switch statements that were intended to keep
OpenWatcom happy.  It didn't work, and now we have a more general
solution for the problem, which also ought to be less dangerous.

87646096a9 asm/parser.c: don't call reloc_value() twice, minor cleanups
There is absolutely no reason to call reloc_value() twice while
processing an immediate.  Doing so is both expensive and unnecessary.
Make some more deliberate decorations to try to avoid miscompilation
on OpenWatcom, but I'm not sure this will help enough.

d97cceed61 We can have a WRT for a relative reference

164d24677a Support self-relative expressions in offsets and immediates
Handle, hopefully correctly, self-relative expressions (that is,
expressions of the form X - Y where Y is a symbol in the current
segment, possibly $ or $$) used as offsets or immediates, as opposed
to arguments to Dx statements (which have already been supported for a
while.)

94e4052a8a nasm_build_assert() -> nasm_static_assert()
The C11 standard calls this concept a static assert, so go with that
terminology.

58f37c1736 parser: Get rid of global variable
fixes pvs-studio error 'V707 Giving short names to global variables
is considered to be bad practice. It is suggested to rename 'i' variable.

gorcunov@: Simply define it as local variable.

abd28c9ab9 If we have new features introduced by C11, use them
Instead of using hacks or compiler-specific features, if we have
standard features as defined in ISO C11, use them.

472a7c1d17 Allow relative references to external symbols in data
Allow constructs like:

      dd foo - $

... where foo is an external symbol.  Currently this is only
implemented for extops, i.e. dx opcodes.
