erts: Make erlang:purge_module/1 safe
Problem: erlang:purge_module/1 is not safe in the sense
that very bad things may happen if the code to be purged
is still referred to by live processes.
Introduce erts_internal:purge_module which is the same as the old
erlang:purge_module BIF (except it returns false if no such old module).
Implement erlang:purge_module in Erlang and let it invoke
erts_code_purger for safe purging where all clogging processes
first are killed.
