REORG: http: move the code to different files The current proto_http.c file is huge and contains different processing domains making it very difficult to work on an alternative representation. This commit moves some parts to other files : - ACL registration code => http_acl.c This code only creates some ACL mappings and doesn't know anything about HTTP nor about the representation. This code could even have moved to acl.c but it was not worth polluting it again. - HTTP sample conversion => http_conv.c This code doesn't depend on the internal representation but definitely manipulates some HTTP elements, such as dates. It also has access to captures. - HTTP sample fetching => http_fetch.c This code does depend entirely on the internal representation but is totally independent on the analysers. Placing it into a different file will ease the transition to the new representation and the creation of a wrapper if required. An include file was created due to CHECK_HTTP_MESSAGE_FIRST() being used at various places. - HTTP action registration => http_act.c This code doesn't directly interact with the messages nor the transaction but it does so via some exported http functions like http_replace_req_line() or http_set_status() so it will be easier to change only this after the conversion. - a few very generic parts were found and moved to http.{c,h} as relevant. It is worth noting that the functions moved to these new files are not referenced anywhere outside of the files and are only called as registered callbacks, so these files do not even require associated include files.

REORG: include: update all files to use haproxy/api.h or api-t.h if needed All files that were including one of the following include files have been updated to only include haproxy/api.h or haproxy/api-t.h once instead: - common/config.h - common/compat.h - common/compiler.h - common/defaults.h - common/initcall.h - common/tools.h The choice is simple: if the file only requires type definitions, it includes api-t.h, otherwise it includes the full api.h. In addition, in these files, explicit includes for inttypes.h and limits.h were dropped since these are now covered by api.h and api-t.h. No other change was performed, given that this patch is large and affects 201 files. At least one (tools.h) was already freestanding and didn't get the new one added.

REORG: include: split common/htx.h into haproxy/htx{,-t}.h Most of the file was a large set of HTX elements manipulation functions and few types, so splitting them allowed to further reduce dependencies and shrink the build time. Doing so revealed that a few files (h2.c, mux_pt.c) needed haproxy/buf.h and were previously getting it through htx.h. They were fixed.

#include <haproxy/htx.h>
REORG: include: move arg.h to haproxy/arg{,-t}.h Almost no change was needed; chunk.h was replaced with buf-t.h. It dpeends on types/vars.h and types/protocol_buffers.h.

#include <haproxy/arg-t.h>
MEDIUM: http_fetch: Remove code relying on HTTP legacy mode Since the legacy HTTP mode is disbabled, all HTTP sample fetches work on HTX streams. So it is safe to remove all code relying on HTTP legacy mode. Among other things, the function smp_prefetch_http() was removed with the associated macros CHECK_HTTP_MESSAGE_FIRST() and CHECK_HTTP_MESSAGE_FIRST_PERM().

#include <types/channel.h>
MEDIUM: checks/http-fetch: Support htx prefetch from a check for HTTP samples Some HTTP sample fetches will be accessible from the context of a http-check health check. Thus, the prefetch function responsible to return the HTX message has been update to handle a check, in addition to a channel. Both cannot be used at the same time. So there is no ambiguity.

REORG: include: move sample.h to haproxy/sample{,-t}.h This one is particularly tricky to move because everyone uses it and it depends on a lot of other types. For example it cannot include arg-t.h and must absolutely only rely on forward declarations to avoid dependency loops between vars -> sample_data -> arg. In order to address this one, it would be nice to split the sample_data part out of sample.h.
