simpleperf: dump file feature section.
For `record --dump-symbols` option, change from dumping
DsoRecord and SymbolRecord to dumping file feature section.
It is to avoid reading symbols from elf files during recording,
which takes a lot of time. And we don't want to mix optional
data (the symbol tables) with necessary data (the profiling records).

simpleperf: add python report interface on linux.

to access samples.
2. Add simpleperf_report_lib.py to wrap libsimpleperf_report.so.
3. Write report_sample.py to test simpleperf_report_lib.py. The
output format of report_sample.py matches the need of building
FlameGraph.

simpleperf: support hotplug events in record cmd.
1. When a cpu is down, read records from event files on that cpu,
then close those event files.
2. When a cpu is up, open event files on that cpu, and create
mapped buffer for those event files to dump records.
3. Instead of creating a mapped buffer for each event type on each
cpu, we can just create a mapped buffer for all event types on
each cpu.
4. When new event files are created, store a EventIdRecord record in
perf.data to notify record_file_reader.cpp.

Simpleperf: Add SPLIT and SPLIT_END records to handle big records.
Previously we split KernelSymbolRecord because it is > 65535. Then
I found TracingDataRecord can also be > 65535. So it is better to
handle big records when reading and writing perf.data.
record_file_writer.cpp splits a big record into multiple SPLIT
records followed by a SPLIT_END record, and record_file_reader.cpp
restores the big record when reading SPLIT and SPLIT_END records.
Also Add RecordHeader to represent record having size > 65535.

improved. Add Better support in finding symbols for kernel modules.

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.
