Factor out the back ends' plug log functions.

Browse Source 
I'm about to want to make a change to all those functions at once, and
since they're almost identical, it seemed easiest to pull them out
into a common helper. The new source file be_misc.c is intended to
contain helper code common to all network back ends (crypto and
non-crypto, in particular), and initially it contains a
backend_socket_log() function which is the common part of ssh_log(),
telnet_log(), rlogin_log() etc.
