The AVRISP project can now enter PDI mode under both bit-bang and hardware USART connection modes, tested against the XPLAIN board hardware. Still need to complete higher level NVM access code so that the device's memories can be read and written.

PDI NVM enable is fast enough that bare polling is enough without a fixed delay in between each attempt. Make sure the USART transmitter is enabled explicitly when the USART is configured, so that repeated attempts to re-enter PDI mode don't fail due to TXEN not being set.

Fix PDI code - must send NVM enable key least significant byte first, need to make sure Tx and Rx is switched correctly including disabling the output on the Tx line when receiving.

Fix AVRISP PDI protocol - make sure inverted masks have the appropriate parenthesis around them, make sure the BREAK command for the hardware USART has 12 clock cycles exactly. Poll NVM Enable bit in the target's STATUS PDI register with a timeout, as it is not set immediately.

Change over AVRISP project to have both hardware USART and software USART modes for the PDI protocol, when enabled. Fix up PDI initialisation routines.

Fix inverted bit-banged USART logic in the AVRISP project for PDI programming. Add a delay to the clock toggling in the AVRISP project to ensure that the programming speed does not exceed 10MHz under any conditions to satisfy the limits in the datasheet for all target voltages. Fix incorrect pin being used as the DATA in in PDI programming mode.

Make sure that USB_STREAM_TIMEOUT_MS is set in the MassStorageHost ClassDriver demo, so that slow devices don't time out the data pipe. Increase pipe timeout in both MassStorageHost demos to 5 seconds to account for the really slow devices.
Fix TeensyHID bootloader not properly shutting down the USB interface to trigger a disconnection on the host before resetting the AVR.

Document the PDI programming routines implemented so far in the AVRISP project. Add ability to selectively disable ISP programming support in addition to the existing ability to disable PDI programming support.
