2d27c54d48 com_msg: Create new message based COM layer for bootloaders
The main purpose of this new COM implementation is that it is
much simpler, and requires less code space.  This takes a bit
of the pressure off of the CC bootloader which was right at
the limit of available code space in the bootloader partition.

This is not intended to ever be used by the application.

This driver also formalizes the assumptions in the bootloader's
usage of the COM layer.  All messages are assumed to arrive
in atomic chunks from the HID layer.

e22bc0c51b copyright: remove incorrect attribution in boilerplate text
These files do not contain content from the ID in the header.
This name seems to have been cut/pasted all over throughout
the openpilot source tree and should be removed from any files
that should not rightfully be attributed to this person.

481a13609e com: remove all references to PIOS_COM_ReceiveBufferUsed()
The PIOS_COM_ReceiveBufferUsed() function call is no longer
necessary since the same semantics can be achieved using calls
to PIOS_COM_ReceiveBuffer().

5f8760a55c com: Move buffering out of USART/HID layer and into COM layer
This allows the spektrum and sbus receiver drivers to bind
directly to the usart layer using a properly exported API
rather than overriding the interrupt handler.

Bytes are now pushed directly from the usart layer into the
com layer without any buffering.  The com layer performs all
of the buffering.

A further benefit from this approach is that we can put all
blocking/non-blocking behaviour into the COM layer and not
in the underlying drivers.

Misc related changes:
 - Remove obsolete .handler field from irq configs
 - Adapt all users of PIOS_COM_* functions to new API
 - Fixup callers of PIOS_USB_HID_Init()

71e491e3c1 com: mark tx buffer as const throughout API
The com layer transmit functions should provide guarantees
that they will not modify the buffer that you're transmitting.
Declaring the parameter as a pointer to const keeps the underlying
implementations honest.

771a56ca9d com/usart: generalize com driver API
- Created a pluggable COM layer
- Converted COM + USART init into static initializers
  rather than typedefs
- Generalized the USB HID COM API to match the USART
  API.
- Changed USART and COM layers to be data driven rather
  than #ifdef'ing/switching on the specifics of each port

0a9be2dedd USB HID now working and integrated into PIOS_COM.
You can now send and receive packets (up to 63 bytes) just like using the USART port with PIOS_COM.
HID packet length will soon be increased to support maximum UAVTalk message length.

f52a719c1d Updated all PIOS function names to new standard.
New standard to be used is PIOS_Module_Function().
Likewise with OpenPilot, OP_Module_Function() is to be used.
