Process escapes from multiplex slave sessions

This hooks up the escape filter to multiplex slave sessions and makes
the escape state per-session.

Doesn't seem to be working for me in 5.5p1 on Linux. If I send ~. to a
multiplex slave session, it just locks up and stops working. Other
escape sequences seem to work though.

Created attachment 1854
  --> https://bugzilla.mindrot.org/attachment.cgi?id=1854
patch

This "fixes" it, although I'm far from sure that it's the
correct
fix... it does serve to highlight the issue though.

The client never exits because the control socket never gets closed
from the master side.
