1. Update the code:
     roll_dep.py \
       -r <libvpx OWNER> \
       --log-limit 20 \
       --roll-to <libvpx hash> \
       src/third_party/libvpx/source/libvpx

   Use the generated commit message for the roll.

2. Generate .gni and config files.

     cd third_party/libvpx
     ./generate_gni.sh

   Update 'Version' and 'CPEPrefix' in this file if necessary.

3. Amend the commit created by the first step:

     git commit -a --amend

4. Upload the change to Gerrit:

Tools needed to build libvpx:

- generate_gni.sh

Generate config and .gni files that contain the source list for each platform.
Configuration for the build is taken from vpx_config.h for each platform.

- lint_config.sh

A tool to verify vpx_config.h and vpx_config.asm are matched. This also
prints the final configuration after checking.
