Added new interface for FunctionFS. This allows most of
the driver code to exist in userspace. The driver will
automatically use FunctionFS if it is enabled for that
device, otherwise it will default to the kernel driver.
The intention is to eventually deprecate the kernel driver.

Test: New automated tests for MtpFfsHandle, AsyncIO.
Manual testing on each device.
Previously we did not sanity check incoming MTP packets,
which could result in crashes due to reading off the edge of a packet.
Now all MTP packet getter functions return a boolean result
(true for OK, false for reading off the edge of the packet)
and we now return errors for malformed packets.

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.
