Make -Werror possible to control on a per-warning-class basis. While
I was fixing up that code anyway, merge the handling of the -w, -W and
[warning] argument and directives.
Furthermore, make *all* warnings suppressible; any warning that isn't
categorized now belong to category "other". However, for cleanliness
sake an "other" option does not get listed in the warning messages.

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.
