Add API gpgme_op_random_value.

* src/genrandom.c (getrandom_size_t): New.
(gpgme_op_random_value): New.
* src/gpgme.def: Add new function.
* src/libgpgme.vers: Ditto.
* src/gpgme.h.in: Add prototype.

* tests/run-genrandom.c: Add an option to use the new function.

The implementation is not optimized but sufficient for our use case.
Possible improvements for this and gpgme_op_random_bytes are a cache
for random bytes in the context so that we do not need to get out to
gpgme for just a few random bytes.
