* Replace `int` with `s32` as return type for syscalls. * Renamed `SC_Something.*` files with the proper lv2 name `sys_something.*`. * Moving away from the lv2, those functions and folders that doesn't correspond to lv2 functions. E.g. module functions from sys_io, sysPrxForUser, cellGcmSys. * Splitted some files (memory -> memory+mmapper) and merged other ones (event+event_flag ->event, spu+spu_thread -> spu), according to common sense, PSDevWiki docs, and checking firmware files. * Removed external functions from `SysCalls.h`. NOTE: What should we do about: cellGcmCallback? It's not a lv2 syscall but it appears on the sc_table and it is actually called in games. Is this some kind of hack?
