Detect whether libtraceevent is installed and if so build against
it. If not installed, warn and build a subset of perf that works
without libtraceevent. With nothing using the now out-of-date
tools/lib/traceevent remove it.

Discussed on LKML here:
https://lore.kernel.org/lkml/CAP-5=fWxAjEia-Qbm0RVzKOxyiod8rUOBieqaGK=DtQboDe3Qw@mail.gmail.com/

Builds upon:
https://lore.kernel.org/lkml/20221116224631.207631-1-irogers@google.com/

Based on discussion of the v1 patch set:
https://lore.kernel.org/lkml/20221117224952.358639-1-irogers@google.com/
v2 conditionally compiles a subset of perf that doesn't require
libtraceevent to avoid having to have libtraceevent installed on a
system.

The changes build upon the fix in:
https://lore.kernel.org/lkml/20221129192924.1580537-1-irogers@google.com/

Ian Rogers (4):
  perf util: Make header guard consistent with tool
  perf util: Add host_is_bigendian to util.h
  perf build: Use libtraceevent from the system
  tools lib traceevent: Remove libtraceevent
