7a8d7d75df qemu: monitor: Introduce qemuMonitorBitmapRemove
The non-transaction wrapper is useful for code paths which want to
delete individual bitmaps or for cleanup after a failed job where we
want to attempt to delete every bitmap individually to prevent a failure
from cleaning up the rest.

1c2314b938 qemu: Update to new design of 'block-export-add'
qemu decided to modify the arguments of 'block-export-add' to include an
array of bitmaps rather than a single bitmap.

Since we've added the code prior to qemu setting the interface in stone
and thus it will be changed incompatibly and we already have tests for
the new interface we need to update the code and qemu capabilities data
at the same time.

Use a array of bitmaps as the 'bitmaps' argument instead of 'bitmap' and
bump qemu capabilities for the upcoming 5.2.0 release to
v5.1.0-2827-g2c6605389c

bac02e396d qemu: monitor: Add helper for generating data for block bitmap merging
Introduce qemuMonitorTransactionBitmapMergeSourceAddBitmap which adds
the appropriate entry into a virJSONValue array to be used with
qemuMonitorTransactionBitmapMerge. Bitmap merging supports two possible
formats and this new helper implements the more universal one specifying
also the source node name.

In addition use the new helper in the testQemuMonitorJSONTransaction
test.

4b658bfe4b qemumonitorjsontest: Validate more commands against schema
The DO_TEST() macro in qemumonitorjsontest.c was not passing the
schema through, which meant that we were not validating any of those
tests for correct usage according to the schema.

In the process of mechanically altering tests to pass the schema
through, use VIR_AUTOPTR on all of the affected test instances. The
next patch will do some further cleanups that it exposes.

Tested by using this hack, where the test mistakenly passed pre-patch,
but correctly diagnosed the garbage post-patch:
