Destroy allocated values when exiting GDB
When the user exits GDB, we might still have some allocated values in
the chain, which, in specific scenarios, can cause problems when GDB
attempts to destroy them in "quit_force". For example, see the bug
reported at:
https://bugzilla.redhat.com/show_bug.cgi?id=1690120
And the thread starting at:
https://sourceware.org/ml/gdb-patches/2019-03/msg00475.html
Message-ID: <87r2azkhmq.fsf@redhat.com>
In order to avoid that, and to be more aware of our allocated
resources, this commit implements a new function "finalize_values" and
calls it from inside "quit_force".
Tested by the BuildBot.

* top.c (quit_force): Call 'finalize_values'.
* value.c (finalize_values): New function.
