Add function to get user information by UID

Browse Source 
Moving to a uid_t to store the user information makes a lot
of sense. When doing this, we need a function to get information
about a user from the uid_t

As well as creating the function g_getuser_info_by_uid() we also
rename g_getuser_info() to g_getuser_info_by_name() and make the
parameter ordering more usual.
