Tomas Vondra	d70b17636d	amcheck: Move common routines into a separate module ... Before performing checks on an index, we need to take some safety measures that apply to all index AMs. This includes: * verifying that the index can be checked - Only selected AMs are supported by amcheck (right now only B-Tree). The index has to be valid and not a temporary index from another session. * changing (and then restoring) user's security context * obtaining proper locks on the index (and table, if needed) * discarding GUC changes from the index functions Until now this was implemented in the B-Tree amcheck module, but it's something every AM will have to do. So relocate the code into a new module verify_common for reuse. The shared steps are implemented by amcheck_lock_relation_and_check(), receiving the AM-specific verification as a callback. Custom parameters may be supplied using a pointer.
