Log message:
	* src/common/kapi.cxx:
	* include/kapi.h:
	Added function cyg_thread_get_next(), cyg_thread_find() and
	cyg_thread_get_info() to allow the current set of threads to be
	enumerated, and per-thread information to be retrieved safely.
	
	* doc/kernel.sgml: Documented new KAPI calls.
	
	* src/common/thread.cxx: Zero unique_id in thread destructor so
	that a stale thread pointer can be checked for validity.
	
	* include/instrmnt.h:
	Added cyg_instrument_state() to report the current state of an
	instrumentation flag.
	Moved ifdef for CYGDBG_KERNEL_INSTRUMENT_MSGS out of within FLAGS
	ifdef. We can have messages without flags.
	
	* src/instrmnt/meminst.cxx:
	Added cyg_instrument_state() to report the current state of an
	instrumentation flag.
	Modified cyg_instrument_msg() in line with header and table
	changes.
	
	* host/instr/dump_instr.c:
	* host/instr/instrument.sh:
	* include/instrument_desc.h:
	Added a final NULL element to the generated table in
	instrument_desc.h to mark its end. Otherwise code that does not
	have access to the table definition cannot find its end. Also
	added ifdefs to allow instrument_desc.h to be used to acquire the
	structure definition and table pointer.
