Jiewei Qian 13d20527ff metadata: use os.walk to speedup metadata file discovery 
os.walk is more efficient than the current handwritten traversal.

Measured the time to scan reduced from 30s+ to 8s on p920 on
chromium/src.

`followlinks=True` is set to preserve behavior that os.path.isdir
returns True for symlink to directories, and the current traversal code
will descend into those.

Validation for Chromium's Third Party Metadata Files

This directory contains the code to validate Chromium third party metadata files, i.e. README.chromium files.

Prerequisites

  1. Have the Chromium source code checked out on disk
  2. Ensure you've run gclient runhooks on your source checkout

Run

metadata/scan.py can be used to search for and validate all Chromium third party metadata files within a repository. For example, if your chromium/src checkout is at ~/my/path/to/chromium/src, run the following command from the root directory of depot_tools:

vpython3 --vpython-spec=.vpython3 metadata/scan.py ~/my/path/to/chromium/src
