Greatly reduce code complexity while providing better support, at
least according to @netstar efl_net_dialer_http works better than
traditional ecore_con_url on BSD.
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.
now that it's runtime dlopen'ed etc. ecore-con "always" has url
support via curl so ecore-file needs to assume that this can always
work and this just use ecore-con-url anyway.
