* remote.c: Fix doc for `C' and `S' commands to indicate full
address.
* (remote_ops extended_remote_ops remote_desc remote_write_size):
Make static.
* (remote_fetch_registers remote_write_bytes remote_read_bytes):
Record size of response to fetch registers command, use this to
limit size of memory read and write commands.
* (push_remote_target): New function to make it possible to have
another target switch to the remote target.
* target.h: Add prototype for push_remote_target.
* sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
for hosts which default to unsigned chars (such as SGI's).
* (_initialize_sh_tdep): Don't set remote_write_size. It's now
handled automatically in remote.c.
