mod_proxy_{connect,wstunnel}: follow up to r1657636. Since rv is not used as an apr_status_t in the loop (it's logging is done by proxy_{connect,wstunnel}_transfer() when necessary/relevent), use a boolean instead to avoid the ugly ORs between APR error codes.

mod_proxy_connect/wstunnel: If both client and backend sides get readable at the same time, don't lose errors occuring while forwarding on the first side when none occurs next on the other side, and abort.

mod_proxy_connect: fix duplicated AH introduced by r1635645.

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 some compiler warnings.

Don't keepalive the connection to the client if the backend closes the connection. PR: 54474 Submitted by: Pavel Mateja <pavel netsafe cz>

* modules/proxy/mod_proxy_connect.c (proxy_connect_handler): Fix use of APLOGNO().

Fix handling of ProxyBlock if a forward proxy is configured, and fix mod_proxy_connect to avoid an inappropriate DNS lookup: * modules/proxy/proxy_util.c (ap_proxy_checkproxyblock): Take hostname argument, make address argument optional. Check names against hostname arg, omit if addr not given. (ap_proxy_determine_connection): Adjust for the above; pass hostname from URI not the next hop. * modules/proxy/mod_proxy_ftp.c (proxy_ftp_handler): Adjust for ap_proxy_checkproxyblock change. * modules/proxy/mod_proxy_connect.c (proxy_connect_handler): Adjust similarly, and avoid the DNS lookup on the request-URI hostname if a proxy is used. * include/ap_mmn.h: Bump MMN.

Add lots of unique tags to error log messages

great proxy logging cleanup: * remove "proxy:", "FCGI", etc. prefixes and pid which are now included in the error log format * propagate frontend request's logconfig to backend request * use ap_log_rerror where possible * remove obsolete APLOG_NOERRNO

Cleanup effort in prep for GA push: Trim trailing whitespace... no func change

mod_proxy_http, mod_proxy_connect: Add 'proxy-status' and 'proxy-source-port' request notes for logging PR: 30195

Introduce new function ap_get_conn_socket() to access the socket of a connection

Introduce ap_(get|set)_core_module_config() functions/macros and use them everywhere. We know that the core module has module_index 0. Therefore we can save some pointer operations in ap_get_module_config(cv, &core_module) and ap_set_module_config(cv, &core_module, val). As these are called rather often, this may actually have some (small) measurable effect.

- Be less verbose at levels INFO and DEBUG in mod_proxy* and mod_ssl - Add some trace logging to core and http

Move error-checking to where it should be Updating r571414 (patch for PR 40756) following rpluem comment

Fix potential proxy segfault PR 40756. Patch adapted from 2.0 patch by Trevin Beattie

Replace ap_get_server_version with ap_get_server_banner() and ap_get_server_description(). High-level summary: The full server version information is now included in the error log at startup as well as server status reports, irrespective of the setting of the ServerTokens directive. Third-party modules must now use ap_get_server_banner() or ap_get_server_description() in place of ap_get_server_version().
