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.

3ebed50146 disasm: Add support for 64-bit origin
This fixes disassembly of instructions like jmp/call when target address
is larger than 2^32-1, and also printing of current address when it's
large.

After this change ndisasm still assumes that the files to disassemble
will never reach 4GiB: only offsets are made 64 bit, but not lengths.

3478078c5f disasm: matches -- fix operator priority error with parenthesis
fixes pvs-studio error 'V502 Perhaps the '?:' operator works in a different way
than it was expected. The '?:' operator has a lower priority than the '!=' operator.'

e29e321e62 Dont set @mod twice
pvs-studio: V519 The 'mod' variable is assigned values twice successively.
Perhaps this is a mistake. Check lines: 398, 405.
