Only a 'struct perf_cmp_map' forward allocation is necessary, fix the
places that need the header but were getting it indirectly, by luck,
from env.h.

Now that evlist.h isn't included by any other header, we can check where
it is really needed, i.e. we can remove it and be sure that it isn't
being obtained indirectly.

Even more, to have a "perf_record_" prefix, so that they match the
PERF_RECORD_ enum they map to.

Move the PERF_RECORD_AUXTRACE_INFO event definition to libperf's
event.h.
In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used
events to their generic '__u*' versions.

'perf record' and 'perf report --dump-raw-trace' supported in this
release.
Example usage:
# perf record -e arm_spe/ts_enable=1,pa_enable=1/ dd if=/dev/zero of=/dev/null count=10000
# perf report --dump-raw-trace
Note that the perf.data file is portable, so the report can be run on
another architecture host if necessary.
Output will contain raw SPE data and its textual representation, such
as:
0x5c8 [0x30]: PERF_RECORD_AUXTRACE size: 0x200000 offset: 0 ref: 0x1891ad0e idx: 1 tid: 2227 cpu: 1

Other release notes:
- applies to acme's perf/{core,urgent} branches, likely elsewhere
- Report is self-contained within the tool.
Record requires enabling the kernel SPE driver by
setting CONFIG_ARM_SPE_PMU.
- The intel-bts implementation was used as a starting point; its
min/default/max buffer sizes and power of 2 pages granularity need to be
revisited for ARM SPE
- Recording across multiple SPE clusters/domains not supported
- Snapshot support (record -S), and conversion to native perf events
(e.g., via 'perf inject --itrace'), are also not supported
- Technically both cs-etm and spe can be used simultaneously, however
disabled for simplicity in this release
