Remove make_cleanup_restore_target_terminal

This removes make_cleanup_restore_target_terminal and generally
C++-ifies target terminal handling.  It changes all target_terminal_*
functions to be static members of a new target_terminal class and
changes the cleanup to be a scoped_* class.
make_cleanup_override_quit_handler is also removed in favor of simply
using scoped_restore.

Note that there are some files in this patch that I could not compile.
Considering that some of the rewrites were automated, and that none of
these files involed cleanups, I feel that this is relatively safe.

Regression tested by the buildbot.
