about current_gdbarch

[Tea]

Hi Thiago,

In your mail, you want me remove the "current_gdbarch" from my patch.
But it's so hard to me.
Because most of "current_gdbarch" is used in function "record_message"
and sub-function of it(such as i386_record and mips_record).
"record_message" will be called by function "resume" that use a lot of
"current_gdbarch" in it. So I think get current gdbarch without
"current_gdbarch" is so hard.

Could you please help me about it? Or let me keep "current_gdbarch" in
current time. Maybe I can remove it in the future.

Thanks,
