libperf: Add perf_evsel__alloc_id/perf_evsel__free_id functions

Browse Source 
Add perf_evsel__alloc_id()/perf_evsel__free_id() functions to libperf as
internal functions.

Move 'struct perf_sample_id' to internal/evsel.h header and change
'struct perf_sample_id::evsel' to 'struct perf_evsel' and the related
code that touches it.
