perf evsel: Add arch_evsel__hw_name()

The commit 55bcf6ef314ae8ba ("perf: Extend PERF_TYPE_HARDWARE and
PERF_TYPE_HW_CACHE") extends the two types to become PMU aware types for
a hybrid system. However, current evsel__hw_name doesn't take the PMU
type into account. It mistakenly returns the "unknown-hardware" for the
hardware event with a specific PMU type.

Add an arch specific arch_evsel__hw_name() to specially handle the PMU
aware hardware event.

Currently, the extend PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE is only
supported by X86. Only implement the specific arch_evsel__hw_name() for
X86 in the patch.

Nothing is changed for the other archs.

perf tools: Add machine_pid and vcpu to perf_sample

When parsing a sample with a sample ID, copy machine_pid and vcpu from
perf_sample_id to perf_sample.

Note, machine_pid will be zero when unused, so only a non-zero value
represents a guest machine. vcpu should be ignored if machine_pid is zero.

Note also, machine_pid is used with events that have come from injecting a
guest perf.data file, however guest events recorded on the host (i.e. using
perf kvm) have the (QEMU) hypervisor process pid to identify them - refer
machines__find_for_cpumode().

perf tools: Factor out evsel__id_hdr_size()

Factor out evsel__id_hdr_size() so it can be reused.

This is needed by perf inject. When injecting events from a guest perf.data
file, there is a possibility that the sample ID numbers conflict. To
re-write an ID sample, the old one needs to be removed first, which means
determining how big it is with evsel__id_hdr_size() and then subtracting
that from the event size.

- Don't bail out when synthesizing PERF_RECORD_ events for pre-existing
threads when one goes away while parsing its procfs entries.

- Don't sort the task scan result from /proc, its not needed and
introduces bugs when the main thread isn't the first one to be

perf offcpu: Accept allowed sample types only

As offcpu-time event is synthesized at the end, it could not get the
all the sample info. Define OFFCPU_SAMPLE_TYPES for allowed ones and
mask out others in evsel__config() to prevent parse errors.

Because perf sample parsing assumes a specific ordering with the
sample types, setting unsupported one would make it fail to read
data like perf record -d/--data.

perf record ibs: Warn about sampling period skew

Samples without an L3 miss are discarded and counter is reset with
random value (between 1-15 for fetch PMU and 1-127 for op PMU) when IBS
L3 miss filtering is enabled. This causes a sampling period skew but
there is no way to reconstruct aggregated sampling period. So print a
warning at perf record if user sets l3missonly=1.

Ex:

# perf record -c 10000 -C 0 -e ibs_op/l3missonly=1/
WARNING: Hw internally resets sampling period when L3 Miss Filtering is enabled
and tagged operation does not cause L3 Miss. This causes sampling period skew.
