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.
some functions were being checked but their IFDEF not being handled,
others (getpwnam and getgrnam) were isolated in a code that is now
Windows, then no need to check them as well as these are POSIX.
