[PATCH v2 1/3] Add public function read_blob_data_from_index_path()

From
LFLukas Fleischer <git@cryptocrack.de>

In-Reply-To
<1365787573-597-1-git-send-email-git@cryptocrack.de>
* Make the read_index_data() function public, rename it to
  read_blob_data_from_index_path() and move it from attr.c to
  read-cache.c.
* Add a use_index parameter to specify a custom index_state since we are
  no longer enable to access the static use_index variable from attr.c.
This allows for reusing the function in convert.c later.
