The phypUUIDTable_Push and phypUUIDTable_Pull leaked their fd's on normal
return. I also noted that the Read function had a cut-n-paste error from
the write function on a couple of VIR_WARN's
The openSSHSession leaked the sock on the failure path. Additionally that
turns into the internal_socket in the phypOpen code. That was neither saved
nor closed on any path. So I used the connnection_data->sock field to save
the socket for eventual close. Of interest here is that phypExec used the
connection_data->sock field even though it had never been initialized.
