Also introduce new supported RAW image file formats, PEF and SRW.
RAW image file formats are not defined in PTP 1.2 specification except
for DNG. They are mostly built on top of TIFF or TIFF/EP. (Fuji's RAF
is the exception).
In this CL, image file formats are classified newly as below:
DNG: dng
TIFF: cr2, nrw, arw, rw2, orf, pef, srw
TIFF/EP: nef
Unknown Image Formats(FORMAT_DEFINED): wbmap, webp, raf
I referred to the following documents for defining MTP formats of RAW
images:

audio/ogg has been the official mimetype for ogg vorbis audio for
a while now, so we should support it.

To do this we need to move the logic for determining media type to MediaProvider
Make some things in MediaFile public so they can be used from MediaProvider

Note: dependent on external/flac for libFLAC
Implemented and tested:
* FLAC container
* mono and stereo
* standard sample rates
* standard bit depths
* sniffer
* media scanner
* Vorbis comment metadata including album art
* random access seeking with "torture test"
* web browser integration for audio/flac (not audio/x-flac), but
note that most web servers don't correctly report the MIME type
Not implemented:
* 24-bit to 16-bit dither or noise shaping in AudioFlinger
* 96 kHz to 44.1 or 48 kHz downsampling low pass filter in AudioFlinger
* replay gain is better done in AudioFlinger
* multi-channel, would need AudioFlinger support
* Ogg container, does not seem to be very popular yet

The native media scanner no longer filters files based on file extension.
Audio, video, image and playlist files are handled as before, but non-media
files are now inserted into the "files" table, which was originally added
to support MTP.

MTP file transfers happen in two stages. The SendObjectInfo command sends
some information about the file and reserves an ObjectHandle for the new file.
The file transfer is then performed using the SendObject command.
To support this in the media provider, MtpDatabase.beginSendObject receives
the information from SendObjectInfo and creates an row for it in the MTP objects
table for the new file. After the file transfer has completed, then
MtpDatabase.endSendObject is called. In endSendObject, we run the media scanner
on the new file, which will add a row to the images, audio, video
or audio playlist table.
To avoid the media scanner creating a second row for the file in the MTP objects
table, we pass the ObjectHandle created in beginSendObject to the media scanner,
which then passes it to the media provider via the content values when it
performs its insert.

Uses a new "MTP objects" table in the media provider to support basic
enumeration of the external storage file system.
Support for accessing audio, video and image metadata in the existing
media provider tables will be added in a later commit.
The C++ MtpDatabase class is now abstract, to support a proxy subclass that
calls through JNI to the Java MtpDatabase class in the media provider.
