This patch adds a 'back-sock' backend. The intention is to provide a backend for
custom logic which is as flexible and easy to prototype as back-shell, but which
works with a multithreaded slapd and with persistent backend processes.

A man page is included (but I'm not familiar with troff macros so you may wish
to check it).

Any other documentation which lists available backend modules will need
updating. I am aware there's a list of backends in slapd.conf(5) but there may
be others.
