Refactor disassembly code
This patch addes class gdb_disassembler, and refactor
code to use it. The gdb_disassembler object is saved
in disassember_info.application_data. However,
disassember_info.application_data is already used by
gdb for arm, mips spu, and scm-disasm. In arm and mips,
.application_data is gdbarch, but we can still get gdbarch
from gdb_disassember.
The use of application_data in spu is a little bit
complicated. It creates its own disassemble_info, and
save spu_dis_asm_data in .application_data. This will
overwrite the pointer to gdb_disassembler, so we need
to find another place to save spu_dis_asm_data. I
extend disassemble_info, and put "id" there.
