This PR synchronises the core with irixxxx's fork (https://github.com/irixxxx/picodrive). After merging, irixxxx's fork should become our new upstream.
The changes include many fixes and optimisations. Perhaps more importantly, now that we are in lock-step with irixxxx's fork, future updates will be trivial to pull into the libretro repo.
Many, many thanks to @irixxxx for all the long hours of work that were required to make this possible, and for the seemingly endless list of improvements that have been made to the picodrive code.
