Rename time and index parameter to avoid name conflict.

Browse source 
As noted in #557, several functions use 'index' resp. 'time'
as parameter names in their declaration and/or definition, causing name
conflicts with the functions in the C standard library of the same
name some compilers warn about.

This commit renames the arguments accordingly.

The PK and RSA modules use different types for passing hash length and
without these checks the type cast could lead to data loss. Found by Guido
Vranken.
* Avoid shadowing of time and index functions through mbed TLS function
arguments. Found by inestlerode. Fixes #557.
