simpleperf: add META_INFO feature section in perf.data. META_INFO section can be used to pass some small information in perf.data. Add simpleperf_version in META_INFO section for debugging. Bug: http://b/37960318 Test: run simpleperf_unit_test. Change-Id: If17a147bbc77b5af063fbf77e02ca81430afb8a5

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). Bug: http://b/32340274 Test: run simpleperf_unit_test. Test: run simpleperf runtest.py. Change-Id: I0a387de243afac93486fc885f223a58060ec07f4

simpleperf: dump tracing data when needed. When monitoring tracepoint events, dump tracing data to perf.data can enable reporting on a different machine. Bug: 27403614 Change-Id: Ie1af624717a245cacbeb44b4c1bcd499fc9ad8db

Simpleperf: remove dependency on global current_arch. When running unit tests on arm64 devices: [OK] ReportCommandTest.dwarf_callgraph [OK] record_cmd.dwarf_callchain_sampling. ERROR: can't unwind data recorded on a different architecture. It is because ReportCommandtest.dwarf_callgraph opens a perf.data recorded on x86_64, and changes current_arch. It causes a problem when the test record_cmd.dwarf_callchain_sampling calls libbacktrace built on aarch64. Athough it doesn't make the test fail, we should fix this.

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. Bug: 26214604 Change-Id: I40812ee5f4f6051103d40459edf4b4a2d7a80313

Simpleperf: Don't load whole perf.data into memory. perf.data can be too large to be loaded into memory. To avoid this, use fread() instead of mmap() to read perf.data, and always use RecordCache to sort records. Fix unit tests failure caused by previous change.
