238032505f util: Introduce virCryptoGenerateRandom
Move the logic from qemuDomainGenerateRandomKey into this new
function, altering the comments, variable names, and error messages
to keep things more generic.

NB: Although perhaps more reasonable to add soemthing to virrandom.c.
    The virrandom.c was included in the setuid_rpc_client, so I chose
    placement in vircrypto.

1ce9c08ab3 util: Introduce encryption APIs
Introduce virCryptoHaveCipher and virCryptoEncryptData to handle
performing encryption.

 virCryptoHaveCipher:
   Boolean function to determine whether the requested cipher algorithm
   is available. It's expected this API will be called prior to
   virCryptoEncryptdata. It will return true/false.

 virCryptoEncryptData:
   Based on the requested cipher type, call the specific encryption
   API to encrypt the data.

Currently the only algorithm support is the AES 256 CBC encryption.

Adjust tests for the API's

701b0f1867 qemu: parse: Handle suffixes for -m memory
According to QEMU docs, the '-m' option for specifying RAM is by default
in MiB, and a suffix of "M" or "G" may be passed for values in MiB and
GiB respectively. This commit adds support and a test for the same.

71d2c172ed qemu: bulk stats: Don't access possibly blocked storage
If the stats for a block device can't be acquired from qemu we've
fallen back to loading them from the file on the disk in libvirt.

If qemu is not cooperating due to being stuck on an inaccessible NFS
share we would then attempt to read the files and get stuck too with
the VM object locked. All other APIs would eventually get stuck waiting
on the VM lock.

Avoid this problem by skipping the block stats if the VM is online but
the monitor did not provide any stats.

90b9995d1d perf: add support to perf event for MBM
Some Intel processor families (e.g. the Intel Xeon processor E5 v3
family) introduced some RDT (Resource Director Technology) features
to monitor or control shared resource. Among these features, MBM
(Memory Bandwidth Monitoring), which is build on the CMT (Cache
Monitoring Technology) infrastructure, provides OS/VMM a way to
monitor bandwidth from one level of cache to another.

With current perf framework, this patch adds support to perf event
