Add CRC code.
Add KVH UART tester.
Update Makefile to include CRC code and enable IMU.
Move crc table initialization to source file.
Enable external crystal oscillator and update imu_debug() to receive full
packet.
IMU port should be 921kbaud, not 460k.
Merge branch 'master' of https://code.google.com/p/atrias into medulla_imu
Upgrade kvh_comm script.
Flush buffer properly.
This code works sometimes. It literally changes behavior at compile time.

Something's horribly wrong. :(
Receive packets from IMU at 10 Hz and display on debug port.
Fix includes.
Print CRC table in test.
Wait for entire packet.
Increase IMU buffer length.
Fix debug output for IMU Medulla.
Fix CRC function debug printout.

So CRC works, after all.
Add CRC field to IMU EtherCAT frame.
Use correct index for UDINT.
Use correct subindex numbers.
