Merge r1387603, r1388029, r1420124, r1421288, r1421912, r1422943, r1422980, r1430575, r1439404 from trunk:

wtf are we doing merging in these from the parent??
These are server specific!


OK, enable/allow previous broken, bad behavior iff the user
really, really wants it. And warn that b-m isn't recommended
in those cases.

rjung's suggestions...

inherit inherit


Use inherit_set to let the global server set
the default for all vhosts.

Otherwise inherit would need to be disabled
redundantly in each vhost.


restrict inherit control to those fields that "require" it...

Redfine - we are just worried about balancers and workers, so have the directive clear about that.

Naming


ProxyPassInherit directive
