This commit introduces two new functions to stop and restart target processes that shared code can use and that clients must implement. It also changes some shared code to use these functions. gdb/ChangeLog: * target/target.h (target_stop_ptid, target_continue_ptid): Declare. * target.c (target_stop_ptid, target_continue_ptid): New functions. * common/agent.c [!GDBSERVER]: Don't include infrun.h. (agent_run_command): Always use target_stop_ptid and target_continue_ptid. gdb/gdbserver/ChangeLog: * target.c (target_stop_ptid, target_continue_ptid): New functions.
