Implement remote multi-process extensions.

* remote.c (struct remote_state): Add extended and
multi_process_aware fields.
(remote_multi_process_p): New.
(PACKET_vKill): New.
(record_currthread): Use thread_change_ptid.  Notice new
inferiors.
(set_thread, remote_thread_alive): Use write_ptid.
(write_ptid, read_ptid): New.
(remote_current_thread, remote_threads_extra_info): Use them.
(remote_threads_info): Likewise.  Detect new inferiors.
(remote_start_remote): Add inferior to inferior list.
(remote_multi_process_feature): New.
(remote_protocol_features): Add "multiprocess" feature.
(remote_query_supported): Pass "multiprocess+" as supported
features.
(remote_open_1): Clear multi_process_aware.  Set extended
accordingly.
(remote_detach_1): Detach current process.  Use extended packet
format for extended-remote multi-process.  Detach process from the
inferior list.  Only mourn after printing output.
(extended_remote_attach_1): Add process to the inferior list.
(remote_vcont_resume): Use write_ptid to pass the thread ids.
(remote_wait): Use read_ptid.  Implement the extended
multi-process extension format of the 'W' and 'X' reply packets.
Remove exited inferiors from inferior list.
(remote_xfer_memory): Set general thread.
(remote_vkill): New.
(extended_remote_kill): New.
(remote_mourn_1): Discard all inferiors.
(select_new_thread_callback): New.
(extended_remote_mourn_1): If there are more processes to debug,
switch to a thread in another process, and don't pop the target.
(extended_remote_create_inferior_1): Add the new process to the
inferior list.
(remote_stopped_by_watchpoint): Indenting.
(remote_xfer_partial): Set the general thread.
(remote_pid_to_str): If the remote is multi-process aware, print
the process id as well as the thread id.
(remote_get_thread_local_address): Use write_ptid.
(init_extended_remote_ops): Register extended_remote_kill.
(_initialize_remote): Register new packets.  Change
magic_null_ptid's, not_sent_ptid's and any_thread_ptid's pid
member to 42000.

* thread.c (thread_change_ptid): Also account for the inferior pid
changing.

* inferior.h (discard_all_inferiors): Declare.
* inferior.c (discard_all_inferiors): New.
