fsdev: - Removed fsdevGetDefaultFileSystem and default-fs handling - Refactored CWD support to have (dynamically allocated) per-device CWDs (CWD support as a whole can be turned off with __nx_fsdev_support_cwd) - Optimized calls by passing pointer to device through r->deviceData - Use the per-thread path buffer directly as the argument to FS functions - Removed redundant cross-device check in fsdev_rename - Fixed string comparison logic in fsdevFindDevice - fsdev_fixpath now accepts an input device in order to skip device lookup (extensively used along with r->deviceData) - Mounting a filesystem now automatically sets the default device if there wasn't any previous default device (or if it's stdnull) - fsdevMountSdmc no longer sets cwd to the folder containing the executable - this logic was moved to a new internal function called on startup by default (and it is now disabled for NSOs) - Other miscellaneous optimizations romfsdev: - Cleaned up romfsMount* functions, removed unused/unnecessary logic - Changed romfsMount* functions to return real result codes - Renamed romfsMount to romfsMountSelf and improved documentation - Removed romfsInitFromFile and romfsInitFromStorage (use Mount instead) - Added documentation for romfsInit and romfsExit
