simpleperf: fix report_sample_test.
When running cmd_report_sample.* tests, it may call
ReportSampleCmd()->Run() more than once. If we shutdown
protobuf library in one call, using protobuf in the
following calls will encounter failures.
Bug: http://b/37996565
Test: run CtsSimpleperfTestCases.

simpleperf: fix unknown binary in samples.
1. Wrong ip addresses in callchain can map to unknown binary. They
should be omitted.
2. When unknown binary is really hitted in samples, which is unlikely
to happen, make sure report-sample cmd will not skip the file id of
unknown binary.
3. Add corresponding test.

simpleperf: dump only needed symbols in file feature section.
Instead of dumping all symbols in the hit elf files, dump only
needed symbols can save a lot of space. To do so, read perf.data
after recording to collect hit file and symbol information.
Bug: http://b/32340274
Test: test using `simpleperf record --dump-symbols` manually.
Test: run simpleperf_unit_test.

simpleperf: use file records in protobuf output.
Dump file name and symbol name for each CallChainEntry
takes too much space. So instead we store file_id and
symbol_id for each CallChainEntry, and store file
records separately.
In CallChainEntry, replace ip with vaddr_in_file, because
vaddr_in_file is more useful in finding instructions in
elf file.

simpleperf: add python report interface on linux.
1. Build libsimpleperf_report.so on host, which exports functions
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: add vaddr_in_file sort key in report command.
Currently report command can't report more details than function name.
After adding vaddr_in_file sort key, it can report the place of the
instruction being sampled. vaddr_in_file is the instruction's virtual
address in elf file, which matches output generated by objdump.
