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.

libperf: Adopt simplified perf_evsel__open() function from tools/perf
...
Add a perf_evsel__open() function to libperf.
It's a simplified version of evsel__open() without the fallback
mechanism.
We can try to merge it in the future to libperf, but it has many
details, lets start simple, requiring the latest kernel, perf should
continue using its evsel__open() version, continuing to support running
on older kernels when possible.

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.
