Unified eina critical macro to CRI.
Unified eina critical macro to CRI.

Being annoyed by different types of eina critical macros - CRI, CRIT,
 CRITICAL -, I concluded to unify them to one. Discussed on IRC and
 finally, CRI was chosen to meet the consistency with other macros -
 ERR, WRN, INF, DBG - in terms of the number of characters.
If there is any missing bits, please let me know.
