[channels.c channels.h clientloop.c]
Add an "ABANDONED" channel state and use for mux sessions that are
disconnected via the ~. escape sequence. Channels in this state will
be able to close if the server responds, but do not count as active channels.
This means that if you ~. all of the mux clients when using ControlPersist
on a broken network, the backgrounded mux master will exit when the
Control Persist time expires rather than hanging around indefinitely.
bz#1917, also reported and tested by tedu@. ok djm@ markus@.
