improve proxy error path properly release everything when during client_close if the request was managed by a proxy.

always mark requests as done when their code is != 20

set REQUEST_PROXY only when proxy_init is successful

fix comment

shuffle the code a bit to improve readability

fix and sync gg usage

note who requested what

bail out of client_read if we've already decide what to do libevent2 can still somehowe call client_read even in code paths that never enable reading from the evbuffer. Can't reproduce on the libevent in base on OpenBSD. It's a bit ugly, but it's a small workaround for something that otherwise *always* make gmid crash when linked against libevent2. (client_read works under the assumption that c->host != NULL, matched_proxy crashes otherwise.)

tweak comment

tweak a sentence

some Pa -> Ar; while here drop two `The' from the start of the sentence

document `require client ca' for proxies

add missing prototype

add `require client ca' for proxy blocks refactor the code that calls validate_against_ca into an helper function to reuse it in both apply_require_ca and (optionally) in apply_reverse_proxy.

ignore .d too
