SVN users can continue using the projects directly, they *just* need
to change the SVN repository location of every project to GitHub.

It can't get simpler than that.

There are plenty of good documentation
(https://git-scm.com/book/en/v2) that teaches everything one needs to
know about git (but was afraid to ask).

Using the umbrella project, the sub-modules will make it trivial to
bisect. Using SVN view for individual projects will make it
*identical* to bisect as it was.

Git imerge is an amazing tool, but it's not production quality yet, I
think. Though, this is really an orthogonal issue, since SVN-bound
people can still use the SVN view and merge their own patches
