- 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

Added support for SPI slave configurations to the pios SPI layer.
Converted the board specific configuration for the PIOS SPI layer to
use const static initializers rather than #defines (see pios_board.c).
SPI interface between the OP board and the AHRS is now operational at
a basic level, capable of moving simple single byte messages between
boards. Multi-byte, CRC protected messages will be added on top of this.

Split the floss-jtag.cfg file into separate versions
for OP and AHRS.
Push AHRS onto non-default ports for gdb, tcl and
telnet.
Update the AHRS gdb setup script to point at the new
gdb port.
Add (commented out) example sytax to support distinguishing
between multiple floss-jtag boards that don't have serial
numbers. Uses the usb bus address of each device as the
selector. See this patch posted to the openocd mailing list
for how to add this functionality to openocd:

nmeaProcess was attempting to null-terminate the
NMEA sentence but was not considering that the
preceeding loop may have looped beyond the end
of the packet buffer.

Both EVents and ERrors were mistakenly being mapped to the
EVent IRQ channel.

This commit fixes all existing warnings.
All basic compiler warnings will now be treated as errors.

This fixes the COM interface over USB HID to the point where
it can establish and maintain solid communications with the UAVObject
Browser in the GCS.
Tested only on Linux. The USB HID interface is still disabled for now
until it is tested successfully by a wider group.
Edit telemetry.c and set ALLOW_HID_TELEMETRY to 1 to enable telemetry
over the USB HID interface and report your results in the forum.

This module reads from the BMP085 pressure sensor. It periodically
updates the pressure (kPa) and temperature (C) as well as the
calculated altitude (m).

FreeRTOS has a strict requirement that even interrupt-safe API calls (ie.
those ending in "FromISR") can only be called from ISRs that are at lesser
or equal priorities to configMAX_SYSCALL_INTERRUPT_PRIORITY. See the
"configKERNEL_INTERRUPT_PRIORITY and configMAX_SYSCALL_INTERRUPT_PRIORITY"
section at:
http://www.freertos.org/a00110.html
The interrupt numbers used on the Cortex-M3 CPU has a somewhat backward
representation of the interrupt numbers so 255 = lowest priority and
0 = highest priority.
The calculation is further complicated by the STM32 implementation only using
the upper 4 bits of the priority value. Only 0x00, 0x10, 0x20, ..., 0xE0, 0xF0
represent useful interrupt priorities.
FreeRTOS requires that MAX_SYSCALL and KERNEL interrupt priorities are expressed
as raw unshifted 8-bit values to be programmed directly into the BASEPRI register.
The priority values passed to the NVIC initialization, however, are expected
to be 4-bit values and are shifted up by 4 within NVIC_Init() for you.
The end result is that we need this arrangement:
[highest priority]
NVIC_0 (Non-maskable-interrupt)
NVIC_1
NVIC_2
[Must NOT call FreeRTOS APIs above here]
configMAX_SYSCALL_INTERRUPT_PRIORITY (now at 48 = 0x30 = NVIC_3)
PIOS_IRQ_PRIO_HIGHEST (cur. NVIC_4)
PIOS_IRQ_PRIO_HIGH (cur. NVIC_5)
PIOS_IRQ_PRIO_MID (cur. NVIC_8)
PIOS_IRQ_PRIO_LOW (cur. NVIC_12)
configKERNEL_INTERRUPT_PRIORITY (240 = 0xF0 = NVIC_15)
[lowest priority]
The previous config had configMAX_SYSCALL_INTERRUPT_PRIORITY set at
191 (0xBF) which is effectively NVIC_11. This was allowing all of
the MID, HIGH and HIGHEST interrupt handlers to preempt the OS in
its critical sections. Since some of these ISRs were calling
FreeRTOS APIs, this would result in corrupting internal data structures
within the OS.
It should be ok to move the configKERNEL_INTERRUPT_PRIORITY to a higher
priority as long as it is less than configMAX_SYSCALL_INTERRUPT_PRIORITY.
