Since there are a number of function pointers in X509_STORE that might
lead to user code, it makes sense for them to be able to lock the
store while they do their work.

OpenSSL 1.1.0-pre5 has made some additional structs opaque. Python's ssl
module requires access to some of the struct members. Three new getters
are added:

int X509_OBJECT_get_type(X509_OBJECT *a);
STACK_OF(X509_OBJECT) *X509_STORE_get0_objects(X509_STORE *v);
X509_VERIFY_PARAM *X509_STORE_get0_param(X509_STORE *ctx);
