mod_proxy_connect: Don't issue AH02447 on sockets hangups, let the read
determine whether it is a normal close or a real error. PR 57168.

Abort the client or backend connection on polling errors, but don't forcibly
abort the client side at the end (the core filters will do that otherwise
when necessary), so that lingering close and SSL shutdown can occur on normal
close.

Fix a potential crash with response headers' size above 8K.

The code changes to mod_authnz_fcgi keep the handle_headers()
function in sync between the two modules.  mod_authnz_fcgi
does not have this issue because it allocated a separate byte
for terminating '\0'.
