e892dcb033 bmp085: create semaphore prior to configuring irq
Since the EXTI and NVIC init routines automatically enable the IRQ when it
is configured, it is possible for the EOC interrupt to fire immediately
upon configuring the IRQ.

Since the handler for the EOC interrupt (EXTI15_10_IRQHandler) does a
xSemaphoreGiveFromISR, it is important to have the semaphore initialized
prior to enabling the interrupt.

Also, added missing include for altitude module.

41da33c920 irq_stack: provide a proper IRQ stack for FreeRTOS
The MSP (IRQ stack) was trampling across the data segment.  This was
especially disastrous in the USB interrupts since they allocate and
fill buffers on the stack.

The root of this trampling was that no RAM was being reserved for the
MSP and a hard-coded value of (0x20000400) was used as the initial MSP
base address.  This resulted in the first 1K bytes of the .data segment
overlapping with the IRQ stack.  As can be expected, all sorts of badness
resulted when interrupts were firing and trampling over variables.

This change reserves the first _isr_stack_size bytes at the beginning of
RAM for the MSP.  If an ISR call chain runs off of the end of the MSP,
a Hard Fault will be generated as the (now invalid) sp is accessed.

There are two stack pointers in the Cortex-M3 CPU.  These are MSP (Main
Stack Pointer) and PSP (Process Stack Pointer).

Which stack is in use at any given time is determined by the following table:

   Mode      CONTROL[ASPSEL]    Stack
   ----      ---------------    -----
   Thread    0                  MSP
   Thread    1                  PSP
   Handler   x                  MSP

Out of reset, the CPU is in Thread mode using the MSP.  The initial value
of the MSP is automatically loaded from address 0 (lowest word in boot
region -- typically FLASH) immediately prior to jumping to the reset vector.

When running at interrupt level, the Cortex-M3 always uses the MSP and the
ASPSEL bit is forced to zero.

FreeRTOS allocates a separate stack for each task upon task creation.  These
task stacks are allocated from the heap.  FreeRTOS sets the active stack to
the PSP whenever running in a task context (both in privileged mode and user
mode).

e3556a3f31 OP-48 Flight/UAVObjects Add access mode field in the metadata. This field can be used to disable local UAVObject updates in the flight or GCS software. It is transparent to any modules and plug-ins, the access control is done by the UAVObjectManager. This functionality is needed for the HITL simulation since certain objects that are normally updated by the flight software (e.g. AttitudeActual, Airspeed etc) will now need to be updated by the GCS. The modules reading those objects do not need to know if the object is updated by the GCS or by the flight software, when HITL is enabled it is transparent to the modules.
NOTE: Delete any metaobjects that you may have saved in the SD card (delete all .obj files).

514d46f5b6 freertos: fix RTOS API calls from interrupt level
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.

e05f4cf068 uavobjects: Added support for generating python classes
The uavobjectgenerator can now generate python classes for each
UAVObject definition.  This is useful for writing simple test
applications in python that can exercise the UAVObject handling
code on the embedded boards.

This is a work in progress so the structure of the generated
classes is likely to change.

0e3a5550ba gdb: Add pre/post hooks to fix step, next, finish
The gdb commands step, next and finish on the M3 core would
never make forward progress since there is almost always an
interrupt pending.  This is a known problem on the M3, and is
fixed by adding pre and post command hooks which mask and unmask
all ISRs on the M3 core.

Step, next and finish now work as expected, but care should be
taken when using these commands across any part of the code that
actually _needs_ the interrupts in order to make forward progress.

42c4c9b343 Lower priority of HIDTest task
Commit @583 uncomments the HIDTest task creation.  HIDTest task is configured to run at
priority 4 (== tskIDLE_PRIORITY + 4) which is higher priority than the "System" task at
priority 3 (== tskIDLE_PRIORITY + 3).

The HIDTest task never blocks so it prevents the system task (and any other task of priority
less than 4) from ever running.

This commit does not fix the root problem of HIDTest never blocking, but rather lowers
its priority to be equal to the system task so that they share the CPU.  This is a
temporary workaround.
