  index: allow read of index w/ illegal entries Allow `git_index_read` to handle reading existing indexes with illegal entries. Allow the low-level `git_index_add` to add properly formed `git_index_entry`s even if they contain paths that would be illegal for the current filesystem (eg, `AUX`). Continue to disallow `git_index_add_bypath` from adding entries that are illegal universally illegal (eg, `.git`, `foo/../bar`).
