This will return the number of currently allocated threads.
Modify the bdev_io caching code to use this new API since these
caches are really per-thread, not per-core. SPDK does not support
dynamic threading yet, but once it does, we will want callers to be
using functions from the thread API - not counting the number of cores
allocated to the application.
spdk_env_get_core_count may still be useful as a helper function, so
it is still kept and not deprecated. For example, app.c uses it to
print the number of cores allocated to the application. bdevperf should
eventually be modified to use spdk_thread_get_count, but holding off on
that for now until spdk_event_allocate() uses threads instead of a reactor
lcore to specify where the event should be executed.

SPDK SCSI layer is relatively matured and these will not be used

Additionally memory leak detected by ASAN is fixed in this patch.

This begins the process of hiding data members in
spdk_bdev_io that don't need to be accessed from
within bdev modules.
One strategy would be to implement accessors for
every data member in the structure. However, that
may have negative performance effects. Instead,
create a new internal structure within the old
structure. This new structure will still be visible
for now, but at least makes clear which members
are accessible and which are not.
This patch shifts one data member to the new structure
as an example.
