MDEV-15104 - Optimise MVCC snapshot
With trx_sys_t::rw_trx_ids removal, MVCC snapshot overhead became
slightly higher. That is instead of copying an array we now have to
iterate LF_HASH. All this done under trx_sys.mutex protection.
This patch moves MVCC snapshot out of trx_sys.mutex.
Clean-ups:
Removed MVCC: doesn't make too much sense to keep it in a separate class
anymore.
Refactored ReadView so that it now calls register()/deregister() routines
(it was vice versa before).
ReadView doesn't have friends anymore. :(
Even less trx_sys.mutex references.
