This patch adds support for blkreplay driver to the blockdev options.
Now blkreplay can be used with -blockdev command line option
in the following format:
-blockdev driver=blkreplay,image=file-node-name,node-name=replay-node-name
This option makes possible implementation of the better command
line support for record/replay invocations.
