Hi,

I'm working on Blackfin port of GDB. Since Blackfin requires that 16-bit 
breakpoint for 16-bit instruction and 32-bit breakpoint for 32-bit 
instruction, Blackfin port GDB tries to read memory, decode instruction, 
and find the instruction length in gdbarch_breakpoint_from_pc. Reading 
memory calls putpkt and getpkt when debugging remotely, which might 
change rs->buf. So we have to call get_remote_state after 
gdbarch_breakpoint_from_pc in remote_insert_breakpoint. Same for 
remote_insert_hw_breakpoint.

Is it OK?
