Update mock/stub usage to remove deprecation warnings
Remove unused stub_libzmq method

This method has the old usage of mock/stub! but was generating no warnings.  A
search through the code demonstrates it is not used anywhere, so remove.
Track pid in Context and Socket finalizers

If a socket is created prior to fork then the reference to the socket (and the
context) will carry forward to the child process.  When the child process exits
it will try to finalize the socket from the parent and a segfault results:

  Assertion failed: ok (mailbox.cpp:84)
  Abort trap: 6

Looks like they ran into the same thing on the perl wrapper and they fixed the
issue by tracking the pid where the socket/context is created.  Only the
original process will finalize the object.  See:
https://github.com/lestrrat/ZeroMQ-Perl/issues/42

In some experiments this works mostly but causes something to hang
sporadically.  Perhaps if the child exits prior to the parent the child is
still waiting for the parent to finalize the socket and context... I don't
know and ran out of time to investigate.
