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. Change-Id: I81aab279975b600b59d99013ab97f9adf0b58da7 Signed-off-by: Mike Lockwood <lockwood@android.com>
