simpleperf: fix callchains generated by the kernel.
The kernel stores return addrs in the callchain, but we
want the addrs of call instructions along the callchain.
So adjust callchains generated by the kernel.
Also avoid using const_cast<> in record.cpp by constructing
Record classes with non const buffers.
Bug: None.
Test: `python report_html.py --add_disassembly`.
Test: run simpleperf_unit_test.

simpleperf: exclude kernel callchains when needed.
Exclude kernel callchains when users only monitor events in user space.
After this change, when users use `record -e cpu-cycles:u --trace-offcpu`,
the samples of the implicitly added sched:sched_switch event won't contain
any kernel callchain.

Fix static-analyzer memory leak warnings.

of memory pointed to by 'r2'
system/extras/simpleperf/record_test.cpp:77:3: warning: Potential leak

system/extras/simpleperf/record_test.cpp:77:3: warning: Potential leak

Bug: None.
Test: Now builds without those warnings, and
`simpleperf_unit_test -t system/extras/simpleperf/testdata` passes.

simpleperf: keep binary in class Record.
It removes memory copy and heap allocation/deallocation in
Record::BinaryFormat(), and is a preparation to remove memory
copy and heap allocation in Record constructor.

simpleperf: add report-sample command.
1. Add report-sample command to report each sample with symbol information.
2. Add --dump-symbols option to record command to collect dso and symbol
information in perf.data.

simpleperf: support reporting more than one event type.
When sampling kernel trace points, it is like to sample more than
one even type. Like `simpleperf record -e kmem:mm_page_alloc,kmem:mm_page_free`.
1. change record command to dump event_id for all records.
2. change report command and record reader to support multiple
event attrs.
3. hide record_cache inside EventSelectionSet.
4. add test to report multiple event types.

Simpleperf: adjust sort strategy in RecordCache.
In order to report correctly, We should keep the order of self created
records when reading perf.data. So adjust sort strategy in RecordCache
to avoid reordering it.

Simpleperf: do stack unwinding while recording.
Dumping user's stack consumes lots of disk space, which makes long period recording
impossible. This patch does stack unwinding before writing to perf.data, so it doesn't
need to save user's stack. Previous behavior is still supported with --post-unwind option.
A record cache is used for online record processing.
