Put local variables in a struct

This way we can have a single call to mbedtls_zeroize, which
saves a few bytes of code size.

Additionally, on my PC, I notice a significant speed improvement
(x86_64 build with MBEDTLS_AESNI_C disabled, gcc 5.4.0 -O3). I don't
have an explanation for that (I expected no measurable difference).
