lib/event: Use spdk_thread_lib_init_ext() to initialize thread library

Browse Source 
Remove the prefix "spdk" from spdk_reactor_schedule_thread(), add
spdk_reactor_thread_op() and spdk_reactor_thread_op_supported().

For SPDK_THREAD_OP_NEW, spdk_reactor_thread_op() calls
_reactor_schedule_thread() and spdk_reactor_thread_op_supported()
returns true.

Then replace spdk_thread_lib_init() by spdk_thread_lib_init_ext()
with spdk_reactor_thread_op() and spdk_reactor_thread_op_supported().
