65038b0840
This change does the following:
- Always use {,new_}http_archive rather than git_repository
- Make liberal use of strip_prefix
- Clarify licenses() in BUILD files
- On POSIX include headers like a normal C/C++ program
This change accomplishes the following:
- Reduce download size >100MB: The biggest culprit is grpc which has
tens of thousands of commits in its GitHub repository.
- Reduce disk size >200MB: On disk, grpc takes up 250MB when cloned even
though the tarball of the git repo is 3.2MB. By never using git
externals, we save on network.
- Consume less cpu: Cloning git repositories is much slower than
downloading and extracting a tarball.
