c4d6465aa7 tests: testQemuCapsIterate: Pass prefix and version to callback
Right now we're passing a "base" string that contains both,
separated by an underscore. Some changes that we're going to
introduce later will require us to have the version number on its
own, and instead of delegating the task of splitting the two apart
to the callback it make more sense to perform it upfront.

This change results in quite a bit of churn because we're now
using the version number only, without the prefix, to calculate
the dummy microcodeVersion.

f73e62a17c Revert "qemu: add socket datagram capability"
This reverts commit 0cebb6422a.

This capability is not used anywhere and also it is not contained
in any release so it's safe to just remove it.

598ec0db68 qemu: Check for drop-cache capability
QEMU 4.0.0 and newer automatically drops caches at the end of migration.
Let's check for this capability so that we can allow migration when disk
cache is turned on.

6abda7a445 backup: Add two new qemu capabilities
Add two capabilities for testing features required for the upcoming
virDomainBackupBegin: use block-dirty-bitmap-merge as the generic
witness of bitmap support needed for checkpoints (since all of the
bitmap management functionalities were finalized in the same qemu 4.0
release), and the bitmap parameter to nbd-server-add for pull-mode
backup support.  Even though both capabilities are likely to be
present or absent together (that is, it is unlikely to encounter a
qemu that backports only one of the two), it still makes sense to keep
two capabilities as the two uses are orthogonal (full backups don't
require checkpoints, push mode backups don't require NBD bitmap
support, and checkpoints can be used for more than just incremental
backups).

Existing code is not affected by the new capabilities.
