Merge 48023786cf63fc4ca90d0c3876d0d578c07d2f68: 'Generate SDK Repository XML.' Do not merge.

When the "sdk_repo" modified is used during the SDK build,
this also generates the repository.xml and addon.xml files
for the new SDK repository packages and places them in
the DIST_DIR.

Example usage:
  make -j 16 PRODUCT-sdk-sdk showcommands sdk_repo dist DIST_DIR=/dist/sdk
  make -j 16 PRODUCT-google_sdk-sdk_addon showcommands sdk_repo dist DIST_DIR=/dist/addon

Also merges 3ea87ca65fa449e981c5a5dfc6ca6a215be0f5aa
  'Fix XMLNS detection in SDK Repo XSD files.'
  to prevent a merge conflict later on.
