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.
