It is possible for a user to disable attribute-based filtering when
committing by doing one of the following:

 * Create .git/info/attributes unapplying all possible transforming
   attributes.
 * Use git hash-object and git update-index to stage files manually.

Doing the former requires keeping an up-to-date list of all attributes which
can transform files when committing or checking out. Doing the latter is
difficult, error-prone and slow when done from scripts.

Instead, similarly to git hash-object, --no-filter can be added to git add
to enable temporarily disabling filtering in an easy to use way.

These patches:

 * Add new flag ADD_CACHE_RAW to add_to_index()
 * Add new flag HASH_RAW to index_fd()
 * Make git hash-object use the new HASH_RAW flag for consistency
 * Add tests for the new git-add option.

Andrej Shadura (2):
  add: add option --no-filters to disable attribute-based filtering
  hash-object: use the new HASH_RAW flag instead of setting path to NULL
