These new names are much more clear and are aligned with other
functions such as spdk_blob_close.
Keep the old names around for now but deprecate them. We will
remove them in next release.

This allows a channel's request_set resources to be
used for queuing I/O requests. This is needed
for upcoming thin provisioning functionality,
where we must queue I/O requests that need to
allocate a cluster, if another cluster allocation
is in progress.

This clarifies that the read/write/etc. operation is

clarification will be important in some upcoming
patches which will batch similar operations on a
blob (as part of splitting a user request into smaller
operations if it spans a cluster boundary).

Unmap does not guarantee that erased blocks will return all zeroes.
using write_zeroes when unmapping metadata gives the
desired behavior for a blob.
Only metadata pages will be cleared with write_zeroes in this patch;
blob data clusters will still call unmap. This behavior may be made
configurable in a later patch (to allow the user to request zeroing of
clusters rather than just unmapping).

Fixes condition where blobstore was prematurely calling the
application callback on spdk_bs_unload(), if the application
tries to do something too quickly bad things happen.
To avoid application changes with how the g_devlist_mutex is
held, it is no longer held while calling
_spdk_io_device_attempt_free() because the app unload CB is
called from that function and may want to call
spdk_io_device_unregister() from its unload CB. So the lock
is now held and releases strictly around the list its
protecting which allows the CB from _spdk_io_device_attempt_free()
to be called without issue.

Most of the work here revolves around having to split

we need to allocate a separate iov array, and then
issue each sub-I/O serially, copying the relevant
