Refactor disassembler selection

Browse Source 
Nowadays, opcodes/disassemble.c:disassembler selects the proper
disassembler according to ABFD only.  However, it actually
selects disassemblers according to arch, mach, endianess, and
abfd.  This patch adds them to the parameters of disassembler,
so that its caller can still select disassemblers in case that
abfd is NULL (a typical case in GDB).

There isn't any functionality change.
