Fix context locking

Some parts of OPENSSL_CTX intialisation can get quite complex (e.g. RAND).
This can lead to complex interactions where different parts of the library
try to initialise while other parts are still initialising. This can lead
to deadlocks because both parts want to obtain the init lock.

We separate out the init lock so that it is only used to manage the
dynamic list of indexes. Each part of the library gets its own
initialisation lock.

Fixes #9454
