This allows mapping an nvme_request back to the
nvme_bdev_io.
This requires bumping up the max number of arguments per
tracepoint. 5 was previously chosen as max since it
exactly fit in 64 bytes (1 cacheline) when all
arguments were stored as uint64_t, but now that we
support uint32_t arguments we can afford extra
arguments when some of them are uint32_t. I've
bumped it to 8 so we can avoid having to touch
this value multiple times if we find some cases
where we need 7 or 8 args.

This will allow us to map spdk_bdev_io events
to nvme_request events coming in a future patch.
Since we pass the nvme_bdev_io to the nvme driver
(not the spdk_bdev_io), we need to add tracepoints
for the nvme_bdev_io so that spdk_trace can
do the spdk_bdev_io->nvme_bdev_io->nvme_request
mapping.
An alternative would have been to pass the spdk_bdev_io
as the cb_arg to the nvme driver, but that change
seemed to invasive, and I think we will find other
uses for the nvme_bdev_io events anyways.

hold the returned array by rdma_get_devices().
RDMA device has PD, context, ref. count, and removed flag. If context
is missing in rdma_get_devices(), set the removed flag to true. Then,
if the ref count becomes zero, free the PD and the RDMA device.
The ref. count of a RDMA device is incremented when spdk_rdma_get_pd()
is called and decremented when spdk_rdma_put_pd() is called.
To simplify synchronization, sort the returned array by
rdma_get_devices().
To avoid resource leakage, add destructor function and free all PDs
and related data at termination.

There may be for_each operations outstanding on an
io_device when it is unregistered. Currently we just
return when this happens, not unregistering the
device but also not notifying the caller that this
happened (since it returns void, and the callback
function doesn't have a status parameter either).
We could just push this responsibility to the caller,
to never unregister an io_device if it knows it has
outstanding for_each calls waiting to complete. But
I think we can simplify this a lot by just handling
this inside of the thread library. Mark that the
device is pending registration, and unregister it
(on the original requesting thread!) when the
for_each count gets back to zero. Also don't
allow any new for_each operations either.
Note this requires a bit of refactoring on the
thread unit tests, since it is now possible to
unregister a device with outstanding for_each
operations.
Fixes issue #2631.

When decoupling a snapshot from its parent, we need to clear its parent.
So we should remove the xattr BLOB_SNAPSHOT. Modifying the xattrs of a blob
only works if its metadata are not in read-only mode.
By default, a snapshot is in read-only mode so this operation fails. When we
later want to delete the snapshot, we will see that it has a parent, so we will
try to remove the snapshot from its parent's clones list. This will cause a
crash.
The fix is to remove the BLOB_SNAPSHOT xattr only after setting the snapshot's
metadata in rw mode.
