Deprecate AES_ige_encrypt() and AES_bi_ige_encrypt()
These undocumented functions were never integrated into the EVP layer
and implement the AES Infinite Garble Extension (IGE) mode and AES
Bi-directional IGE mode. These modes were never formally standardised
and usage of these functions is believed to be very small. In particular
AES_bi_ige_encrypt() has a known bug. It accepts 2 AES keys, but only
one is ever used. The security implications are believed to be minimal,
but this issue was never fixed for backwards compatibility reasons.
