In change Ic5b3fb75309893caae1a4f4b56068a543847f1f7, we added partial
support for the MTP properties:
MTP_PROPERTY_AUDIO_WAVE_CODE,
MTP_PROPERTY_BITRATE_TYPE
MTP_PROPERTY_AUDIO_BITRATE
MTP_PROPERTY_NUMBER_OF_CHANNELS
MTP_PROPERTY_SAMPLE_RATE
However we were not returning any values for these properties in the result
of the MTP GetObjectPropList command. Strangely, this triggers a nasty bug
in Windows 7 that results in data loss. When copying a directory containing
several MP3 files from one location on the device to another, Windows will
copy only some of the files to the new location, but delete all of the originals.
Finishing the implementation of these new object properties for some unknown
reason stops this bad behavior in Windows 7.

Implemented reading and writing state to retain information
across boots, API to retrieve state from it, improved location
manager interaction to monitor both coarse and fine access
and only note operations when location data is being delivered
back to app (not when it is just registering to get the data at
some time in the future).
Also implement tracking of read/write ops on contacts and the
call log. This involved tweaking the content provider protocol
to pass over the name of the calling package, and some
infrastructure in the ContentProvider transport to note incoming
calls with the app ops service. The contacts provider and call
log provider turn this on for themselves.
This also implements some of the mechanics of being able to ignore
incoming provider calls... all that is left are some new APIs for
the real content provider implementation to be involved with
providing the correct behavior for query() (return an empty
cursor with the right columns) and insert() (need to figure out
what URI to return).

Added new API to enable cancelation of SQLite and content provider
queries by means of a CancelationSignal object. The application
creates a CancelationSignal object and passes it as an argument
to the query. The cancelation signal can then be used to cancel
the query while it is executing.
If the cancelation signal is raised before the query is executed,
then it is immediately terminated.

Make sure previous MtpThread has exited before starting another to avoid
EBUSY opening MTP kernel driver.
