When we close a CLI and it had fd# 0 and/or fd#1, reopen these as /dev/null so the will not be reused for the CLI pipe to the child on next restart, otherwise stdout/stderr output from the manager would get sent there and confuse the clients CLI reader. Don't double free a pointer to the CLI buffer. Accept non-zero results from cli_readres() errors are non-fatal. Use stderr more consistently for manager debugging. git-svn-id: http://www.varnish-cache.org/svn/trunk/varnish-cache@749 d4fa192b-c00b-0410-8231-f00ffab90ce4
