Replace GC_NO_RETRY_SIGNALS environment variable with GC_RETRY_SIGNALS=0
* doc/README.environment (GC_NO_RETRY_SIGNALS): Remove.
* doc/README.environment (GC_RETRY_SIGNALS): Document "0" value.
* pthread_stop_world.c [!GC_OPENBSD_UTHREADS && !NACL] (GC_stop_init):
Declare str local variable; do not check GC_NO_RETRY_SIGNALS
environment variable; refine comment; set GC_retry_signals to false
if the value of GC_RETRY_SIGNALS environment variable is "0".
