Improve reporting for mutex errors

Browse Source 
Replace all uses of RUNTIME_CHECK() in lib/isc/include/isc/mutex.h with
ERRNO_CHECK(), in order to improve error reporting for any mutex-related
run-time failures (by augmenting error messages with file/line/caller
information and the error string corresponding to errno).
