7d4582e5f0 Update the altitude KF to use the updated measurements appropriately and check 
in the relevant matlab code to check it and genererate it.  Produces quite
smooth traces.

c957172f8f In the case of swapping in userspace due to the buffer being blocked during 
ISR, make sure the latency is less than 50 us to avoid framesync errors.  Still
seeing a few nonsense packets on Overo side but fairly few.  Probably need to
add CRC to whole packet now and call it done.

1930d092eb In the case where the overo scheduler cannot swap buffers (userspace loading 
it) then set a flag so as soon as the buffer is loaded then we schedule it.

f04c58b0f4 Make the overo transaction occur based on the rising edge of the NSS line. 
This fixes most of the frame sync problems.  However, it's a bit hacky as
there is currently hardware information inside a module.

3026527801 Now the desired altitude is relative to when the switch was flipped so that the 
baro altitude module can use a smoothed altitude estimate for the starting
point.

5b2376dbee Remove the semaphore for buffer swapping and make this occur during the receive 
ISR.  This leads to a possible condition where a copy is taking place in
userspace and then a buffer swap interrupts it.  However, the copy should
always finish before the SPI DMA slave catches up to that place in memory at 10
MHz.

This fixes a common condition where the userspace task (low priority) was not
swapping buffers in time from user space and logs were corrupted.

179e66b754 Refactor how new packets are scheduled to avoid trying to start a transaction 
from an ISR.  This was causing lock ups.  It's a bit higher latency probably
(trivially slow) but if we aren't keeping up with the Overo transactions then
using a proper DMA double buffer will be required.
