This reverts commit aab707ab70.
A different solution to the submodule problem is being considered in #104573.
Revert to the previous behavior that developers are familiar with for now.
The meaning of the ignore option for submodules did change since our
initial Git setup was done: back then it was affecting both diff and
stage families of Git command. Unfortunately, the actual behavior did
violate what documentation was stating (the documentation was stating
that the option only affects diff family of commands). This got fixed
in Git some time after our initial setup and it was the behavior of the
commands changed, not the documentation. This lead to a situation when
we can no longer see that submodules are modified and staged, and it is
very easy to stage the submodules.
For the clarity: diff and status are both "status" family, show and
diff are "diff" family.
Hence this change: since there is no built-in zero-configuration way
of forbidding Git from staging submodules lets make it visible and
clear what the state of submodules is.
We still need to inform people to not stage submodules, for which
we can offer some configuration tips and scripts but doing so is
outside of the scope of this change at it requires some additional
research. Current goal is simple: make it visible and clear what is
going to be committed to Git.
This is a response to an increased frequency of incidents when the
submodules are getting modified and committed without authors even
noticing this (which is also a bit annoying to recover from).

This way we can point submodules to different branches.
There are two side-effects to this:
- Git 1.8.2 becomes the minimal required version now
to support this feature.
- Not sure how doing local changes in submodules followed
by `make update` will behave. We don't use explicit rebase
now.
Perhaps this is not so bad, since it was already quite
dangerous thing to do.
While SCons building system was serving us really good for ages it's no longer
having much attention by the developers and started to become quite a difficult
task to maintain.
What's even worse -- there started to be quite serious divergence between SCons
and CMake which was only accumulating over the releases now. The fact that none
of the active developers are really using SCons and that our main studio is also
using CMake spotting bugs in the SCons builds became quite a difficult task and
we aren't always spotting them in time.
Meanwhile CMake became really mature building system which is available on every
platform we support and arguably it's also easier and more robust to use.
This commit includes:
- Removal of actual SCons building system
- Removal of SCons git submodule
- Removal of documentation which is stored in the sources and covers SCons
- Tweaks to the buildbot master to stop using SCons submodule
(this change requires deploying to the server)
- Tweaks to the install dependencies script to skip installing or mentioning
SCons building system
- Tweaks to various helper scripts to avoid mention of SCons folders/files
as well

Uses relative paths to repositories, so this is expected
to work fine for any protocol we support (git, ssh and http).
Uses ignore=all for all the submodules, so updating them
to latest remote hash does not tags blender repository
as changes. But it is still possible to make changes to
submodules and commit them from their path.
