* Support new elf2dol path in Makefile.griffin
* Fix NULL pointer dereference when no core info is available
* Fix double include of different versions of libogc
* Move ngc and wii to Makefile.common
Resulting binary is 60K *smaller*. This is surprising but probably due to
less inlining happening
* gx_gfx: Fix hang on gfx initialization
* Remove sthread_isself on NGC/Wii
It relies on pthread_equal that is not there for either legacy pthreads
or normal pthreads on those platforms
* Wii networking
* Missing includes in split
* Network fixes
* Fix logging of non-format string as a format
* Support for gx netlogger
* Network fix
* Network fixes
* Network info
* gx: Move config files to app directory
Otherwise it clashes between wiiU and vWii version with unpredictable
effects
- Core info cache can now be enabled/disabled on all platforms via a new `Settings > Core > Cache Core Info Files` option
- Core info cache file has been renamed from `.cache` to `core_info.cache` (i.e. it is no longer a 'hidden' file on Unix platforms, so can be deleted easily)
- The core info cache file is now compressed (rzip) to further reduce disk IO
- The presence of a `core_info.refresh` file in the core info directory will force a one-time refresh of the info cache. This file is generated automatically when toggling on the `Cache Core Info Files` option, and we will also add it to core info file packaging such that updating info files (either manually or via the online updater) will force a refresh
- The core info cache no longer contains 'core is locked' and 'firmware missing' data fields; these are 'dynamic' properties that must be determined at runtime
- The 'core is locked' status is now determined on core info intialisation by parsing the core directory listing, rather than by performing indivdual 'lock file exists' checks. This minimises file IO, and greatly improves performance on devices with slow storage
- While parsing the core info cache file, we now avoid unnecessary `strdup()`s when adding entries to the resultant cache list
- Memory leaks (potential and real) have been fixed, and safety checks added
- Build errors have been fixed
