Remove all use of global:safe_whereis_name/1
Calls to global:whereis_name/1 have been substituted for calls to
global:safe_whereis_name/1 since the latter is not safe at all.
The reason for not doing this earlier is that setting a global lock
masked out a bug concerning the restart of supervised children. The
bug has now been fixed by a modification of global:whereis_name/1.
(Thanks to Ulf Wiger for code contribution.)
