svn rev #21120: branches/mskrb-integ/src/lib/crypto/

[lhoward@MIT.EDU]

Commit By: lhoward
Log Message: 
Refactor code such that an AEAD provider does not need to implement the
older, non-IOV SPIs. Instead, the older APIs will implement their
behaviour on top of the AEAD SPIs, using the wrapper functions in
aead.c.
