Whenever a file is updated in the index, each tree leading towards it
needs to be invalidated. Provide the supporting function.

The fix introduced in a02fc2cd (2011-05-24; index: correctly parse
invalidated TREE extensions) threw out the rest of the data in the
extension if it found an invalidated entry. This was the result of
incorrect reading of the documentation.

Insted, keep reading the extension, as there may be cached data we can
use.

GIT_EOVERFLOW means something different. Use GIT_ESHORTBUFFER. On the
