This was occuring when the source texture was larger than the destination
texture, but the source rect was <= dest rect, so the copy is valid.

Sorts out references that cause some modules to be kept around after
backend shutdown.

Should also solve the issue with errors being thrown due to the config
being loaded after device creation, leading to the incorrect device being
used in a multi-adapter system.

We don't create a device below feature level 11_0 anyway, so no point
checking, we can just assume support.

Resources are already aligned to an address larger than any of our
requirements, anyway.

These were completely broken due to lack of c_str(). We also output
warnings now as well (these can be useful).

Moves render target restoring to RestoreAPIState, this also means no need
to manually restore after allocating in a buffer that caused execution,
because the manager restores it for us.

Remove a method that wasn't used from D3DUtil.cpp, and fixes a few errors
in EFB poke drawing.
