MTP playlists now correspond to playlists in the media provider
(like those created by the Music app).

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.

Rename existing test database to MtpSqliteDatabase
This is the first step in transitioning to using the media provider database

This restricts the driver to the client's permissions when copying files
to avoid potential security problems.

This change includes work in progress on a C++ library for both host and device
MTP and PTP support.
Currently the makefile builds two test programs:
mtptest - a command line test program that implements a small subset of device side MTP.
Requires a kernel driver that has not been checked in yet.
ptptest - a host tool to test USB host support for detecting and communicating with
digital cameras over PTP. Runs on Linux host.
Later this will be reformulated as a native library that will be used in the media process.
