This is essentially just a search and replace to change SRWBackend to
RWBackend* and SRWBackendList to PRWBackends, a vector of a raw
pointers. In the next few commits vector<unique_ptr<RWBackend>>
will be used for life time management.
There are a lot of diffs from the global search and replace. Only a few manual
edits had to be done.
