Detect the capability via the query-qmp-schema for blockdev-add
to find the 'password-secret' parameter that will allow the iSCSI
code to use the master secret object to encrypt the secret for an

line thus obsfuscating the passphrase.

'share-rw' for the disk device configures qemu to allow concurrent
access to the backing storage.

The capability is checked in various supported disk frontend buses since
it does not make sense to partially backport it.

This capability says if qemu is capable of specifying distances
between NUMA nodes on the command line. Unfortunately, there's no
real way to check this and thus we have to go with version check.

Starting from qemu 2.11, the `-device vmcoreinfo` will create a fw_cfg
entry for a guest to store dump details, necessary to process kernel
dump with KASLR enabled and providing additional kernel details.

In essence, it is similar to -fw_cfg name=etc/vmcoreinfo,file=X but in
this case it is not backed by a file, but collected by QEMU itself.

Since the device is a singleton and shouldn't use additional hardware
resources, it is presented as a <feature> element in the libvirt
domain XML.

The device is arm/x86 only for now (targets that support fw_cfg+dma).

All APIs which expect a list of CPU models supported by hypervisors were
switched from char **models and int models to just accept a pointer to
virDomainCapsCPUModels object stored in domain capabilities. This avoids
the need to transform virDomainCapsCPUModelsPtr into a NULL-terminated
list of model names and also allows the various cpu driver APIs to
access additional details (such as its usability) about each CPU model.

Using the query-qmp-schema introspection - look for the 'vxhs'
blockdevOptions type.

NB: This is a "best effort" type situation as there is not a
    mechanism to determine whether the running QEMU has been
    built with '--enable-vxhs'. All we can do is check if the
    option to use vxhs for a blockdev-add exists in the command
    infrastructure which does not take that into account when
    building its table of commands and options.

The switch contains considerable amount of changes:

  virQEMUCapsRememberCached() is removed because this is now handled
  by virFileCacheSave().

  virQEMUCapsInitCached() is removed because this is now handled by
  virFileCacheLoad().

  virQEMUCapsNewForBinary() is split into two functions,
  virQEMUCapsNewData() which creates new data if there is nothing
  cached and virQEMUCapsLoadFile() which loads the cached data.
  This is now handled by virFileCacheNewData().

  virQEMUCapsCacheValidate() is removed because this is now handled by
  virFileCacheValidate().

  virQEMUCapsCacheFree() is removed because it's no longer required.

  Add virCapsPtr into virQEMUCapsCachePriv because for each call of
