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
