[PATCH 0/5] Authenc key parsing consolidation

[Mathias Krause <mathias.krause@secunet.com>]

This series removes the code duplication of authenc key parsing by
introducing a common helper function crypto_authenc_extractkeys() in
patch 1. Patches 2 to 5 change all remaining places to use the new
helper. Patches 3 and 4 also fix potential memory corruptions by
ensuring the supplied keys won't overflow there respective buffers.

I was unable to test patches 3 to 5 as I don't have the needed hardware
for these devices -- not even a cross compiler for those architectures.

In case patches 3 and 4 are enqueued for stable, patch 1 needs to be as
well, as it's a prerequisite for those.

Please apply!
