Compiler will be used for experimentation purpose since it's both easier
to develop in python and it accepts ftrace, making it very easy to write
complicated-experimental changes that we aren't sure are worth it yet
for the on-device C++/perfetto compiler.
This 'new' compiler accepts ftrace/systrace files as input,
then generates an in-memory sqlite3 database (using the trace_analyzer
source code), and finally code-generates a TraceFile.pb protobuf.
(Also refactor trace_analyzer into a library, and update it to
parse systrace.html files)
Limitations: currently does not accept perfetto_trace.pb files due to
'ofs' fields missing (see bug#135555191)
Test: py.test-3 frameworks/base/startop/scripts
Test: ./compiler.py -i tmp_sargo/textcache -t tmp_sargo/trace.html -o tmp/output.pb
Test: ./compiler.py -i tmp_sargo/textcache -t tmp_sargo/trace.html -o tmp/output.pb -f '^/data'
Test: ./trace_analyzer music_run.trace tmp_dbs/12345.db
