[PATCH v5 0/8] Add support for Firefox's gecko profile format

[Anup Sharma]

This patch series adds support for Firefox's gecko profile format.
The format is documented here [1].

I have incorporated several changes based on feedback from the
previous version of the patch.

Changes in v5:
- Reorganized the patch series to ensure that each patch works independently.
- Renamed the file to perf-gecko.py.
- Added command exection support for the script. The script can now be
  executed as "perf script report perf-gecko > output.json."
- Simplified the usage information; previously it was "perf script
  perf-gecko.py > output.json," now it is "perf script report
  perf-gecko > output.json."
- Merged the test and command execution patches into this series,
  which were previously in a separate series.

Committer Testing:
- Tested with a perf.data file generated for single and multiple cpu
  cores enabled.
- Uploaded the stdout into profiler.firefox.com and verified the
  output.
- Verified the output with the output generated by the existing
  script as mentioned here [2].

Method:
- perf record -F 99 -a -g -- sleep 5
- perf script report perf-gecko > output.json
- upload output.json to profiler.firefox.com
