Bug description: Warning about empty IV in ECB mode
Description:
------------
In ECB mode iv is ignored so there should not be any warning when passing
and empty iv string. This was also reported earlier in bugs #43143 and
#46010 which were supposedly fixed.
Reproduce code:
---------------
$td = mcrypt_module_open('tripledes', '', 'ecb', '');
mcrypt_generic_init($td, 'mysecretkey', '');
Expected result:
----------------
No warning. In fact a 'Notice' when a non-empty iv is given in ECB mode
mentioning that it will be ignored would be better.
Actual result:
--------------
Warning: mcrypt_generic_init() [function.mcrypt-generic-init]: Iv size
incorrect; supplied length: 0, needed: 8
