The pattern is shown in logcat and should match the text in iorap.

When using device, the python modules for host are not loaded to be
compatiable in tradefed.

The time in timestamp is second, while the trace duration is
millisecond. Using timedelta to fix this ambiguity.

The basic idea is add timestamp for MmFilemapAddToPageCache.
Treat the first receiving MmFilemapAddToPageCache timestamp as
the start time. The end time is the sum of start time and duration.
Any MmFilemapAddToPageCache after end time is filtered out.

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)

Parse ACTIVITY_FIRST_PREVIEW_FRAME_RECEIVED_ms,ACTIVITY_FIRST_PREVIEW_FRAME_RENDERED_ms
from logcat when running Camera app.
Also updates the scripts to support multiple metrics output (previously
only one allowed). Adding future per-app metrics is also possible by
just adding 1 file with 1 function call with a regex pattern.

Input: either pinlist.meta or a text file.
Output: either text file or iorap.TraceFile protobuf.
Also supports looking inside zip files to find out entry offset
automatically.

Script measures app startup times with/without iorapd-based
prefetching against a cold (or warm) baseline.
mlock/fadvise readahead options now use iorapd to exercise
real code to do prefetching.
