Max Reitz 16789db3de blkdebug: Add @iotype error option 
This new error option allows users of blkdebug to inject errors only on
certain kinds of I/O operations.  Users usually want to make a very
specific operation fail, not just any; but right now they simply hope
that the event that triggers the error injection is followed up with
that very operation.  That may not be true, however, because the block
layer is changing (including blkdebug, which may increase the number of
types of I/O operations on which to inject errors).

The new option's default has been chosen to keep backwards
compatibility.

Note that similar to the internal representation, we could choose to
expose this option as a list of I/O types.  But there is no practical
use for this, because as described above, users usually know exactly
which kind of operation they want to make fail, so there is no need to
specify multiple I/O types at once.  In addition, exposing this option
as a list would require non-trivial changes to qemu_opts_absorb_qdict().
