Using `bs_allocate_and_copy_cluster()` instead of a zero-length write
makes it possible to inflate/decouple snapshots, as the writes would
fail with -EPERM, because the snapshots are marked as read-only.
Additionally, zero-length non-vector requests are now completed
immediately. It makes it consistent with the vector path (which already
does that) and allows us to use the zero-length reads as a context for
cluster copy.
Fixes#2028.

Move the definition of structure spdk_io_channel into

This patch adds mechanism to simulate power failure in
blobstore unit tests at any given moment in time.
This point in time is measured by number of IO operations
occured after triggering power failure with the number
of IO operations given as a parameter. Number of IO
operations parameter can be defined as any type IOs,
writes, reads, unmaps, writes zero or flushes.

Unit tests that use this will still immediately execute
the messages by default. But upcoming changes to
queue persists will need to leverage testing asynchronous
behavior so these changes enable that.
While here, fix some bugs where _bs_flush_scheduler()
did not fully flush the queue of scheduled ops.

This requires exposing struct spdk_io_channel in the
public header - mark it as internal with Doxygen
comments to make it extra clear that applications
should not use the data structure directly.
This is a very hot function in the main I/O path,
so making this function inline has a significant
performance benefit. A bdevperf microbenchmark
using null bdevs shows a 11% improvement.

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).

Most of the work here revolves around having to split
an I/O that spans a cluster boundary. In this case
we need to allocate a separate iov array, and then
issue each sub-I/O serially, copying the relevant
subset of the original iov array.
