* Add support for other engine binaries in game configs (#1414).
* Add engine bin path for CRC bin lookup and filter out addons from GAMEBIN.
* MAX_PATH -> PLATFORM_MAX_PATH.
* Fix library lookup on Linux.
Before this, there was a bad assumption that, like on Windows, POSIX module
handle pointers were within the module's address space (and thus usable
with dladdr). That's not true!
Instead, to get a usable address on all platforms, we'll do a lookup of the
CreateInterface function that exists in all modules. This also has the
(arguable) benefit of further locking this implementation to modules owned
by the game.
To get a valid address inside the module now on both p
