xmllint pre-commit hook

This is a pre-commit hook feeding all files through xmllint. 'xmllint' command is assumed to exists in command path (please use alias if you don't want to have command in a path, or modify the hook).

Operation

format-xmllint overwrites malformed files with reformated file.

check-xmllint hook runs xmllint --format and fails if any modified file doesn't match xmllint --format output. We don't advise to use that option.
