c27feefea1 libperf: Do not export perf_evsel__init()/perf_evlist__init() 
There's no point in exporting perf_evsel__init()/perf_evlist__init(),
it's called from perf_evsel__new()/perf_evlist__new() respectively.

It's used only from perf where perf_evsel()/perf_evlist() is embedded
perf's evsel/evlist.

70c20369ee libperf: Add perf_evsel__alloc_id/perf_evsel__free_id functions 
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.

Export only perf_evsel__enable()/disable(), keeping the
perf_evsel__apply_filter() one private for the moment.

1fc632cef4 libperf: Move perf_event_attr field from perf's evsel to libperf's perf_evsel 
Move the perf_event_attr struct fron 'struct evsel' to 'struct perf_evsel'.

Committer notes:

Fixed up these:

 tools/perf/arch/arm/util/auxtrace.c
 tools/perf/arch/arm/util/cs-etm.c
 tools/perf/arch/arm64/util/arm-spe.c
 tools/perf/arch/s390/util/auxtrace.c
 tools/perf/util/cs-etm.c

Also

  cc1: warnings being treated as errors
  tests/sample-parsing.c: In function 'do_test':
  tests/sample-parsing.c:162: error: missing initializer
  tests/sample-parsing.c:162: error: (near initialization for 'evsel.core.cpus')

   	struct evsel evsel = {
   		.needs_swap = false,
  -		.core.attr = {
  -			.sample_type = sample_type,
  -			.read_format = read_format,
  +		.core = {
  +			. attr = {
  +				.sample_type = sample_type,
  +				.read_format = read_format,
  +			},

  [perfbuilder@a70e4eeb5549 /]$ gcc --version |& head -1
  gcc (GCC) 4.4.7

Also we don't need to include perf_event.h in
tools/perf/lib/include/perf/evsel.h, forward declaring 'struct
perf_event_attr' is enough. And this even fixes the build in some
systems where things are used somewhere down the include path from
perf_event.h without defining __always_inline.
