gdb: introduce 'all_non_exited_process_targets' and 'switch_to_target_no_thread'
Introduce two new convenience functions:
1. all_non_exited_process_targets: returns a collection of all process
stratum targets that have non-exited inferiors on them. Useful for
iterating targets.
2. switch_to_target_no_thread: switch the context to the first
inferior of the given target, and to no selected thread.
gdb/ChangeLog:
2020-05-14 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>
* process-stratum-target.h: Include <set>.
(all_non_exited_process_targets, switch_to_target_no_thread): New
function declarations.
* process-stratum-target.c (all_non_exited_process_targets)
(switch_to_target_no_thread): New function implementations.
