FUNCTION : int AddErrorInBuffer(void* p_lastError)
**************************************************

AUTHOR : AMazy

USE :
Store errors in a circular buffer so we can have an history of errors generation.
This function is called in the macros "SetError" of each task

PARAM :
int* p_lastError : a pointer on an error code (only 16 bits are used)

NOTE :
This function shall always be called inside a critical section.
