gdb: Implement native dumpcore function
Add new API for systems with native kernel support for dumping
a process on demand. Wire it into the gdb's gcore functionality.
gdb/ChangeLog:
* target.h (supports_dumpcore, dumpcore): New
function declarations.
* target.c (supports_dumpcore, dumpcore): New
functions.
* target-delegates.c: Rebuild.
* gcore.c (gcore_command): Use target_supports_dumpcore ()
and target_dumpcore ().
