cmsis-dap: add initial cmsis-dap support
This is based on work from: https://github.com/TheShed/OpenOCD-CMSIS-DAP/tree/cmsis-dap Main changes include moving over to using HIDAPI rather than libusb-1.0 and cleaning up to merge into master. Support for reset using srst has also been added. It has been tested on all the mbed boards as well as the Freedom board from Freescale. These boards only implement SWD mode, however JTAG mode has been tested with a Keil ULINK2 and a stm32 target - but requires a lot more work.
