* shared_info.h (shared_info::initialize): Remove argument.

* cygheap.h (cygheap_user::init): New declaration.
* uinfo.cc (cygheap_user::init): New.
(internal_getlogin): Move functionality to cygheap_user::init.  Open the
process token to update the group sid.
* shared.cc (user_shared_initialize): Get the user information from
cygheap->user.
(shared_info::initialize): Remove argument.  Call cygheap->user.init instead of
cygheap->user.set_name.
(memory_init): Do not get the user name and do not pass it to
shared_info::initialize.
* registry.cc (get_registry_hive_path): Make csid a cygpsid.
(load_registry_hive): Ditto.
