Previously unit tests were run
on the same thread that called
the SPDK init. The bdevio app
had 2 threads: one for init&ut
and one for I/O processing.
When doing any asynchronous I/O,
the init&ut thread was waiting
via pthread condition variable
for I/O thread to finish it's
work.
With upcoming virtio-initiator
RESET implementation, the reset
I/O has to be processed by
a poller on the init thread.
When init&ut thread sends an
RESET requests the app deadlocks,
as pollers on the UT thread
won't be processed until I/O
thread wakes the condition
variable.
This patch separates ut thread
from init, so that init can
run it's tasks in background
even when ut thread is waiting
for condition variable.
