bluetooth: allow media_rw_data_file
Allow bluetooth to handle media_rw_data_file file descriptors
sent to it from other processes. Without this, bluetooth
picture / video sharing is broken.
Steps to reproduce:
1. Take few pictures
2. launch gallery and choose a picture/video and click on share and choose
available BT device and share
Other info from bug report:
- Bluetooth process queries media content provider for a file descriptor,
with an Uri like "content://media/external/images/media/69"
- Media server resolves the uri to a file on the filesystem, in the case of
Gallery at "/storage/emulated/0/DCIM/Camera/IMG_20140128_141656.jpg"
- Media server returns the FD over binder to bluetooth
- Bluetooth is unable to read the file backed by the file descriptor.
