Given that most software is not MT (for good reasons) I won't like to
implement this unconditionally; it might be better to add a configure
flag and build 2 vesions of the library - gpgme-config can then be
used to figure out the needed one.
Or should we provide an additional object file to shortcut the locking

There are not many places which need to be changed. gpgme_wait()
needs to be changed of course, the fail_on_pending_request macro and
the stuff which fires up the backend.

As long as an object is only used by one thread it should be save.
gpgme_cancel() should work from all threads.
