2bdec64fbf jsonrpc: modify API to pass request to handler
This will enable asynchronous request handling in a future patch, and it
also removes the need for the RPC handlers to know about request id and
the JSON-RPC rules about notification-only requests.

57d174ff67 bdev: add spdk_bdev_open/close
Retire the old claim/unclaim semantics in favor of
open/close.  Clients must now open a bdev to get
an spdk_bdev_desc, then pass this desc to get an
I/O channel.

This allows multiple clients to open a bdev,
although only one may open a bdev with write
access.

7f6c737a25 bdev: add virtual to base bdev relationships
Each virtual bdev now has a pointer to its base
bdev, and a base bdev has a pointers to any virtual
bdevs built on top of it.

Also add a new set of leaf iterators, to get only
bdevs that have no virtual bdevs built on top of
them.  These iterators are now used by the bdevio and
bdevperf utilities, in advance of the claim/unclaim
semantics getting removed in a future patch.

9f770dae7e bdev/error: make sure error_disk is not NULL
If the user specifies the name of a bdev that is not an error injection
bdev, bdev_inject_error would cause a NULL pointer dereference.

bac4c02bc4 bdev: change name and product_name to char *
Dynamically allocate bdev names to remove the arbitrary 16-character
name length limit.

All of the existing product_names are constant strings, so those can
just use string literals instead of a copy per bdev.

b9bcc3531e bdev: make enum spdk_bdev_io_status private
The user should not see the bdev_io status directly; the NVMe and SCSI
error code wrappers provide the ability to translate to the desired
format regardless of what kind of error is stored inside the bdev_io.

Replace the spdk_bdev_io_completion_cb status parameter with a bool
simply indiciating whether the I/O completed successfully.
