Ticket: 8518
Keywords that work for HTTP2 headers match now as soon as possible
A push promise is now considered like a headers frame with regards
to the progress (no dedicated "reserved" progress/state)
http.protocol and http.stat_msg keywords are now registered at
earliest progress, since these are synthetic like "HTTP/2" and
not really seen on the wire.
http.request_line and http.response_line match only on data,
and not on headers, since we must wait the end of headers
to be sure to have the full line
http2.size_update now matches at headers progress as it should
http2.frametype, http2.errorcode, http2.priority now match like
http2.window, when the tx is complete from both sides, as a
half-closed client may still send priority, rst_stream
or window_update frames
Rename DetectAppLayerInspectEngineRegister2 to
DetectAppLayerInspectEngineRegister as there is no other variant of
this function, and the versioning with lack of supporting
documentation can lead to confusion.
The old DetectAppLayerMpmRegister has not been around since 4.1.x.
Rename the v2 of this function to a versionless function as there is no
documentation referring to what the 2 means.
Currently, it seems easier to upload the diagram images to git than to
try to make the image generation script work with out of the tree builds
and other corner cases.
This means, however, that one must activelly remember to update msc
diagram files, run the script and re-add new png files, if those ever
need to be updated. To raise awareness to that, a watermark was added
to the diagram images.
Also removed configuration steps that added mscgen as dependency
(locally and for workflow builds and readthedocs).
Moved devguide dir into userguide dir.
Since the devguide is now incorporated as the last chapter of the
userguide, removed build and configuration files from the devguide
dir, as these are no longer needed.
