Fixed and improved the "*_bind" directives of proxying modules.

Browse Source 
The "proxy_bind", "fastcgi_bind", "uwsgi_bind", "scgi_bind" and
"memcached_bind" directives are now inherited; inherited value
can be reset by the "off" parameter.  Duplicate directives are
now detected.  Parameter value can now contain variables.
