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.

QEMU commit 46ea94ca9cf ("qmp: query-current-machine with
wakeup-suspend-support") added a new QMP command called
'query-current-machine' that retrieves guest parameters that
can vary in the same machine model (e.g. ACPI support for x86 VMs
depends on the '--no-acpi' option). Currently, this API has a single
flag, 'wakeup-suspend-support', that indicates whether the guest has
the capability of waking up from suspended state.
Introduce a libvirt capability that reflects whether qemu has the
monitor command.

Added in QEMU commit of v3.0.0-rc0~48^2~9 (then fixed by
v3.1.0-rc0~119^2~37) QEMU is replacing '-realtime mlock' with
'-overcommit mem-lock'. Add a capability to tell if we're dealing
new new enough qemu to use the replacement.

The '-realtime mlock' cmd line argument was introduced in QEMU
commit v1.5.0-rc0~190 which matches minimal QEMU version we
require. Therefore, the capability will always be present.
Apparently, nearly none of our xml2argv test cases had the
capability hence slightly bigger change under qemuxml2argvdata/.

There are a few differences, but the one we're interested in is
that PCIe Root Ports are finally available: as a result of this,
our riscv64-virt-headless guest will switch from virtio-mmio to
virtio-pci.

* parsing/formatting this in the caps cache

Note that when compared to the previous commit which made sure that no
disk related tests were touched, in this case it's not as careful.
