Updated forward declaration
Add rx queue to I2C driver even though it is not used by CSP.
This makes it possible to use the I2C driver with CSP callback and using the blockin I2C driver API at the same time
Added pointer alignment check in csp_buffer_free to avoid dereferencing unaligned pointers
Updated KISS example to new kiss interface and USART driver
Fixed bug in simple.c example
Added build description to kiss example
Added safety check to CRC32
Merge branch 'master' of https://github.com/GomSpace/libcsp
Added experimental support for small fragmentation protocol
Build change: Removed the 'freertos/' part in all #include <freertos/FreeRTOS.h>

This means that you will need to change the include path for FreeRTOS in your main wscript to include the specific folder for the include files.
The reason for the change is in order to make compatability with "Atmel Software Framework" where the freertos includes
does not reside in a 'freertos' subfolder, and hence the foldername in the include directive must go...
Export includes from CSP, this helps when freertos is defined
Removed string warnings if freertos v8.0 is used
Merge branch 'master' of https://github.com/GomSpace/libcsp
Fix SFP compilation on AVR8
Create mtu.md
Update mtu.md
Use csp_malloc instead of malloc
First version of cmp clock functions
Forgot to add csp_clock.h
Added posix clock.c
