[RFA] aix-thread.c: Allow retargeting of threaded targets

[Corinna Vinschen <vinschen@redhat.com>]

Hi,

the following problem occurs on AIX, when the user examines a core file
of a threaded target:

$ gdb -nw application core
[...]
(gdb) run
Starting program: application
You can't do that without a process to debug.
(gdb) quit
The program is running.  Exit anyway? (y or n) y
You can't do that without a process to debug.
(gdb)

Even detaching from the core doesn't help since the current code
doesn't detach in a way so that the aix-thread code would be able
to reinitializes on "run".
The following fix corrects the detach command in that case, so that
the user can run and/or quit gdb by explicitely detaching.

This doesn't solve the still outstanding problem, that the "run"
command should implicitely detach from the previous target, if that
was a core file.

Corinna
