commit f05c5bb521f404592b137e02a1b8abd50da87ca3

Fix segmentation fault when using jq in threads
In previous code nomem_handler in jv_alloc.c is called only once
and therefore the structure is not initialized for second and
following threads.
This leads to segmentation fault in multi-threading environment.
This patch moves initialization of nomem_handler out of the
pthread_once call.
