Reverted modifications to USBInterrupt.h that were intefering with correct host mode operation.

Fixed SUSPI interrupt not being cleared during device mode enumeration, causing accidental mis-fires on re-enumeration.

Fixed JTAG_DEBUG_POINT() and JTAG_DEBUG_BREAK() macros not compiling under pure C99 standards mode.
