- Subject: [RFA] Implement 'detach pid'.
This patch makes CLI 'detach' and MI '-target-detach' accept the PID
of the process to detach from.
Is the infcmd.c change OK?

From 8c0569ee17d85cf591426a0b9900d8cad0e02389 Mon Sep 17 00:00:00 2001
* infcmd.c (_initialize_infcmd): Make 'detach' accept
parameter.
* mi/mi-cmds.c (mi_cmds): Make '-target-detach' pass parameter
to 'detach'.
* remote.c (remote_detach_1): Interpret the passed
parameter as a pid to detach from.
