Added a new write_stat() call to the file descriptor operations (plus syscall).

Browse Source 
Renamed sys_read_stat() to sys_read_path_stat() - sys_read_stat() is now
the fd operation (same for the corresponding write call).
Removed the sys_write_attr_stat() call because it is no longer needed.
Added stat(), fstat(), and other POSIX calls to the kernel - many are still
missing (mainly from stdio).
Added symbols (but no implementation) for unistd.h's process id functions.
Adapted libroot calls that used sys_read_stat() before to the new architecture.
module.c and bus_man.c now use stat() directly instead of the sys_read_path_stat()
call.
