avutil: undo FF_API_CRYPTO_CONTEXT deprecation
...
It's been argued that the benefits of the current implementation far outweight
those of making the structs opaque.
This deprecation is not present in any release, so it can be safely removed.

xtea: fix CBC mode when src=dst
...
In CBC mode, when src=dst and we are decrypting a block different
from the first one, we need to save the current block of ciphertext
(which will constitute the initialization vector for the next block)
before we overwrite it.

xtea: Make the count parameter match the documentation
...
Previously it was interpreted as number of bytes, while the
documentation stated that it was the number of 8 byte blocks.
This makes it behave similarly to the existing AES code.
