[PATCH v1 0/2] gdb: fix for bug 31207

This patch series contains:
- a refactoring suggested by Simon Marchi <[email protected]> in [1] patch 02/10.
- a fix for https://sourceware.org/bugzilla/show_bug.cgi?id=31207.

Those 2 patches were extracted from a previous patch series [1], in order to give more visibility and focus on that fix.

Following up the suggestions of Simon,
1. 'info proc mappings' will print before the thread-group leader exits:
    process 814
  and after the thread-group leader exited:
    process 814 [Note: information where gathered from LWP 816 as the thread-group leader (LWP=814) already exited.]

2. the code selecting the PTID inside was moved to get_process_reference_ptid().
3. a new test in gdb.threads checks that the header is emitted correctly before and after the exit of the thread-group leader.

Regards,
Matthieu
