LibCrypto+LibTLS: Generalise the use of IV length

Browse source 
This is in preparation for the upcoming Galois/Counter mode, which
conventionally has 12 bytes of IV as opposed to CBC's 16 bytes.

...Also fixes a lot of style issues, since the author finally found the
project's clang config file in the repository root :^)
