Get a fragmap for a specific segment of a logical volume using the provided offset and size.
A fragmap is a bitmap that records the allocation status of clusters. A value of "1" indicates
that a cluster is allocated, whereas "0" signifies that a cluster is unallocated.

The channel passed to blob IO operations is useful for tracking
operations within the blobstore and the bs_dev that the blobstore
resides on. Esnap clone blobs perform reads from other bs_devs and
require per-thread, per-bs_dev channels.
This commit augments struct spdk_bs_channel with a tree containing
channels for the external snapshot bs_devs. The tree is indexed by blob
ID. These "esnap channels" are lazily created on the first read from an
external snapshot via each bs_channel. They are removed as bs_channels
are destroyed and blobs are closed.

This is the beginning of support for external snapshots. An external
snapshot is a read-only blobstore device (struct spdk_bs_dev) that can
be used as a blob's back device. Normally a blob will have no back
device (a normal blob), a zeroes back device (a thin provisioned blob),
or a blob back device (a clone blob). When a blob has an external
snapshot ("esnap") as its back device, it is called an esnap clone.
With this patch, esnap clones can be created but they are not yet
useful. Subsequent patches in the series will plumb the IO path, enable
various features, and allow lvol bdevs to be esnap clones.

The goal of a platform driver is to execute chained accel operations in
the most efficient way possible. A driver is aware of the hardware
available on a platform and can execute several operations as a single
one. For instance, if we want to do DMA and then encrypt the data, the
driver can do both at the same time, if the hardware is capable of doing
that.
Platform drivers aren't required to support all operations. If a given
operation cannot be executed, the driver should notify accel to continue
processing a sequence, via spdk_accel_sequence_continue(), and that
operation will processed by a module assigned to its opcode.
It is required however, that all platform drivers support memory
domains, including the "virtual" accel domain. A method for allocating
those buffers will be added in the following patches.
This patch only adds methods to register and select platorm drivers, but
doesn't change the way a sequnce is executed (i.e. it doesn't use the
driver to execute it).

The gpt bdev module has an off-by-one error. When it
calculates the size of the partition, it simply does
"end - start", when really it should be "end - start + 1".
We cannot just fix it by changing the math here, any
consumers of the partition may have put down metadata
on the partition based on the old size.
So instead add a new SPDK partition type. SPDK will keep
the existing off-by-one behavior when it finds the old
partition type, but will use the correct math when finding
the new partition type.
Fixes issue #2801.
