dirstate-v2: Store a hash of ignore patterns (.hgignore)

Later, this help extend `read_dir` caching to directories that contain ignored
files (but no unknown files). Such cache must be invalidated when ignore patterns
change since a formerly-ignored file might become unknown.

This helps the default configuration of `hg status` where unknown files must
be listed, but ignored files are not.
