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.
Task #4909
Update the Ubuntu containers for the commit and formatting checks to
Ubuntu 20.04.
The latest version of the checkout action requires git v2.18 in order to
checkout the code as a git repo, which is required for these workflows.
With older versions of git the action will download the code as a
tarball and lack the .git directory.
Many places were still referencing the old Suricata page.
Used git grep with replace to update them. Checked that new links work.
Left old references when they were only documentation examples (for
output or unittests).
Task#4915
There is currently a build failure with macos-latest (recently updated)
to 11 in the libhtp test suite code. Not sure if there are other
build issues in libhtp or Suricata at this time.
Add library install test to Fedora 33 build. In this case the
shared library is disable so the test makes sure it is not
installed.
Also make sure the library and headers are not installed until
explicitly installed.
Add similar to test to an Ubuntu 24.04 build without disable-shared
and check that the shared library is installed.
