Setup skeleton code (basic daemon).
Added a missing comment.
Introducing an initial implementation of HoTT telemetry support.
Added a note on the inclusion of libraries for UART access in the Makefile.
Merge remote-tracking branch 'upstream/master' into hott
General code cleanup.
Make the reading and sending of data independant of the message type.

This will allow us to cleanly support various sensor types by having a
byte array interface for send_data() and read_data().
Shorten the post read delay slightly.
Tried cleaning up console messaging a bit.
Messaging cleanup.
Fix some memory corruption bugs.
Trying to get single wire working. Not quite there yet.
Single wire now working once moving away from UART5.
Cleanup a bit.
Code formatting cleanup.

Fixed code style with Tools/fix_code_style.sh
Addressed compiler warnings and handle non-supported devices properly.
Push single wire operations into stm32_serial.c and added a test to verify HoTT telemetry setup.
