PR 55475: Detect incomplete body in HTTP input filter and return APR_INCOMPLETE

I see no getpid() or other requirement for process.h here. (the include of process.h was added in r1025496)

Added header include for getpid() prototype on Win32.

core, mod_deflate, mod_sed: Reduce memory usage by reusing bucket brigades in several places

Remove all references to CORE_PRIVATE.

* Do not split the brigade if the flush bucket is the last bucket in the brigade. PR: 23567 Submitted by: Stefan Fritsch <sf sfritsch.de> Reviewed by: rpluem

update license header text

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

Clarify (I hope) the comment better :)

* If a subrequest has a broken backend also set no_cache for the main request and ensure that the chunk filter does not sent the last chunk marker in this case. modules/http/chunk_filter.c: Memorize HTTP_BAD_GATEWAY error buckets that had been seen in filter context to ensure that we do not sent the last chunk marker in this case. modules/proxy/proxy_util.c : Set no_cache also for main request if we are a subrequest. Thanks to Joe Orton and André Malo for the "invented unique pointer" trick.

* If the mod_proxy backend connection broke in the middle of the response, then - Do not cache it. - Signal the client that something went wrong by closing the connection and not sending the last-chunk marker if the response was T-E chunked. server/core_filters.c : Close the connection to the client by setting c->keepalive to AP_CONN_CLOSE. modules/http/chunk_filter.c : Do not send last-chunk marker in the case the backend broke. modules/proxy/mod_proxy_http.c: Signal that the backend connection broke. modules/cache/mod_disk_cache.c: Respect r->no_cache for discarding the response Submitted by: Roy T.

No functional change: remove "internal" tab spacing/formatting.

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

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

* modules/http/mod_core.h: Prototype ap_http_chunk_filter. * modules/http/chunk_filter.c (ap_http_chunk_filter): Rename from chunk_filter. * modules/http/http_core.c (chunk_filter): Remove the original copy. (register_hooks): Register ap_http_chunk_filter.

Initial pass at refactoring some files to eliminate our 150K C source behemoths. * Makefile.in: Change order of dependencies to bring in exports.o first so that we have every symbol 'used' before the linker starts processing. * build/rules.mk.in: Add a 'program-install' target which just copies httpd. * server/Makefile.in, modules/http/config2.m4: Add in new file targets. * NWGNUmakefile, libhttpd.dsp: Blind updates for Netware and Win32.
