Alter the descriptions to match what the cpu_cycles actually is

With current perf framework, this patch adds support and documentation
for more perf events, including cache misses, cache references, cpu cycles,
and instructions.

Add to some details for the existing enum

This function is not used anywhere. Moreover, the code that would
use lives in virperf.c and therefore has access to the FD anyway.
Well, for instance virPerfReadEvent is doing just that.

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
for MBM.

Now that we have @flags we can support changing perf events just
in active or inactive configuration regardless of the other.
Previously, calling virDomainSetPerfEvents set events in both
active and inactive configuration at once. Even though we allow
users to set perf events that are to be enabled once domain is
started up. The virDomainGetPerfEvents API was flawed too. It
returned just runtime info.

This patch implement a set of interfaces for perf event. Based on
these interfaces, we can implement internal driver API for perf,
and get the results of perf conuter you care about.
