* remote-mips.c (mips_expect, mips_getstring, mips_send_packet,
mips_send_packet, pmon_insert_breakpoint, send_srec,
pmon_check_ack, pmon_check_entry_address,
_initialize_remote_mips): Replace the magic two seconds with
``remote_timeout''.
(pmon_check_entry_address, pmon_check_total): New functions. Use
``remote_timeout'' instead of magic two seconds.
(pmon_end_download): Rewrite. Use pmon_check_entry_address and
pmon_check_total.
