This adds a testcase exercising multi-target features. It spawns 6 inferiors, like this: inferior 1 -> native inferior 2 -> extended-remote 1 inferior 3 -> core inferior 4 -> native inferior 5 -> extended-remote 2 inferior 6 -> core and then tests various details, including: - running to breakpoints - interrupting with Ctrl-C and "interrupt -a" - "next" bouncing between two breakpoints in two threads running in different targets. - since we have cores and live inferiors mixed in the same session, this makes sure that gdb doesn't try to remove a core dump's threads. - all-stop and non-stop modes. This testcase caught a _lot_ of bugs in development. gdb/testsuite/ChangeLog: 2020-01-10 Pedro Alves <palves@redhat.com> * gdb.multi/multi-target.c: New file. * gdb.multi/multi-target.exp: New file. * lib/gdbserver-support.exp (gdb_target_cmd): Handle "Non-stop mode requested, but remote does not support non-stop".
