Cure size_t abuse, curse some recent code

Add lots of unique tags to error log messages

Fix compiler warning

Slightly reorganize previously unused dump method. Add AJP packet log method on top of dump method.

axe some useless or debug-inhibiting error checking

fix function name in log text

Fix some compiler warnings: - suggest braces around empty body in an 'if' statement - comparison of unsigned expression >= 0 is always true - comparison of unsigned expression < 0 is always false Please review carefully.

Use the new APLOG_USE_MODULE/AP_DECLARE_MODULE macros everywhere to take advantage of per-module loglevels

* modules/proxy/ajp_msg.c (ajp_msg_dump, ajp_msg_check_header, asj_msg_copy): Fix format string warnings on x86_64.

At support for ProxyIOBufferSize in AJP.

Make sure the error signature is logged as double hex byte.

update license header text

small cleanup of EBCDIC support in mod_proxy_ajp

* Actually we are adding 3 bytes to the string (two for the length in front and a \0 at the end) and not 2. So adjust the length check.

Update the copyright year in all .c, .h and .xml files

No functional Change: Removing trailing whitespace. This also means that "blank" lines consisting of just spaces or tabs are now really blank lines

* Fix PR37100 (SEGV in mod_proxy_ajp), by sending the data up the filter chain immediately instead of spooling it completely before passing it to the filter chain. It contains a bandaid to handle intentional flushes from Tomcat side. Further explanation in code and report. ajp.h: Add ajp_msg_reuse prototype mod_proxy_ajp.c: Adjust logic of ap_proxy_ajp_request ajp_msg.c: Add ajp_msg_reuse ajp_header.c: Adjusting logic of ajp_read_header

Update copyright year to 2005 and standardize on current copyright owner line.

Rewrite Cookies and other headers in mod_proxy_ajp as configured with ProxyPassReverse and ProxyPassReverseCookiePath. * modules/proxy/proxy_ajp.c (ap_proxy_ajp_request): Update call to ajp_parse_header(). * modules/proxy/ajp.h (ajp_msg_get_string): constify argument. (ajp_parse_header): Add conf argument. * modules/proxy/proxy_util.c (ap_proxy_location_reverse_map): Promoted from mod_proxy_http. (ap_proxy_cookie_reverse_map): Promoted from mod_proxy_http; renamed from proxy_cookie_reverse_map. * modules/proxy/ajp_msg.c (ajp_msg_get_string): constify argument. * modules/proxy/proxy_http.c (ap_proxy_location_reverse_map, proxy_cookie_reverse_map: Removed. (process_proxy_header): Update header mapping table to reference the now public functions. * modules/proxy/ajp_header.c (ajp_unmarshal_response): And conf argument. Reverse map cookies and other headers. (ajp_parse_header): Update call to ajp_unmarshal_response(). * modules/proxy/mod_proxy.h (ap_proxy_location_reverse_map, ap_proxy_cookie_reverse_map): Declare functions that have been promoted to be public. (ap_proxy_header_reverse_map_fn): Typedef for the signature of the above two functions (currently used in mod_proxy_http).

Use plain apr/apr-util for ajp.

* modules/proxy/ajp_msg.c (ajp_msg_dump): Cast apr_size_t to unsigned long to avoid the warning with %lx for 32-bit size_t too.

Fix format string warnings in proxy_ajp on 64-bit platforms: * modules/proxy/ajp_header.c (ajp_send_data_msg): Use APR_SIZE_T_FMT. * modules/proxy/ajp_link.c (ajp_ilink_receive): Don't pass \n to ap_log_error; do use APR_SIZE_T_FMT. * modules/proxy/ajp_msg.c (ajp_msg_dump, ajp_msg_check_header, ajp_msg_copy): Use APR_SIZE_T_FMT. (ajp_log_overflow): New function. (ajp_msg_{append,peek,get}_*): Use it. * modules/proxy/proxy_ajp.c (ap_proxy_ajp_request): Use APR_SIZE_T_FMT.
