* boot-9.scm (top-repl): don't flush all ports at exit.

Browse source 
(error-catching-loop): likewise.
* boot-9.scm (scm-style-repl): -read: don't call
consume-trailing-whitespace if val is eof object.  Allows
exiting repl with single control-D.
* boot-9.scm (error-catching-loop): don't force output within
error catching loop after quit received.
(top-repl): flush all ports when the repl terminates.
* boot-9.scm (error-catching-loop): flush all ports before
primitive exit if non-interactive.
force-output on current-error-port if interactive.
* boot-9.scm (reopen-file): deleted.
* popen.scm (open-output-pipe, open-input-pipe): moved from
boot-9.scm.
* popen.scm: new file.
