linux: Add maintenance commands to test libthread_db
This commit adds two new commands which may be used to test thread
debugging libraries used by GDB:
* "maint check libthread-db" tests the thread debugging library GDB
is using for the current inferior.
* "maint set/show check-libthread-db" selects whether libthread_db
tests should be run automatically as libthread_db is auto-loaded.
The default is to not run tests automatically.
The test itself is a basic integrity check exercising all libthread_db
functions used by GDB on GNU/Linux systems. By extension this also
exercises the proc_service functions provided by GDB that libthread_db
uses.
This functionality is useful for NPTL developers and libthread_db
developers. It could also prove useful investigating bugs reported
against GDB where the thread debugging library or GDB's proc_service
layer is suspect.
