gcrypt: Use predefined pthread locking functions instead of custom hooks

Browse Source 
Starting with libgcrypt 1.6, it seems that custom locking functions are not
supported anymore. Instead, the user has to select from one of the pre-defined
set of locking functions.

Given that we have a proper threading abstraction API with optional profiling
on all platforms, this is somewhat annoying. However, there does not seem to be
a way to use custom functions, and we have no other choice than using the
provided macro magic to support all libgcrypt versions.

Fixes #630.
