dfd06ee710 avutil/twofish: Fixed decryption
The previous implementation swapped the two halves of the plaintext. The
existing tests only decrypted data with a plaintext of all zeroes, which is
not affected by swapping the halves. Tests which detect the old buggy behavior
have been added.

07d4fe3a87 avutil: use EINVAL instead of -1 for the return code of crypto related init functions
These functions return an error typically when the key size is an
incorrect number. AVERROR(EINVAL) is more specific than -1.
