bind/connect cleanup.

Rename the existing xbind/xconnect to xbindany/xconnectany, to make room
for new xbind/xconnect that are more like 'x' versions of the regular
bind and connect. Move explicit bind/connect callers over to
xbind/xconnect.

Of the affected commands, only netcat is actually used by Android. It
was the most recent patch to netcat that made the lack of a more
traditional xbind/xconnect apparent.
