Add apache license and cla.

Intention is to rewrite the cla as a license-sounding text.
And perhaps include some of the cla grants in the license.

Remove 'notwithstanding the above' from section 5, and clarify that you
should state different terms when making the Contribution.
The latter is yet another smallish way intended as perhaps giving more
strenght to *these* terms the contribution is under (and no others,
even if that's unavoidable imo.)

The 'nothwistanding' phrase is interestingly speculated as making room
for CLA, and its removal as opening the door to have the CLA-holding entity
bound in some way. I actually don't entirely think so, but I have some
time and coffee.

The inclusion of Submissions clause without this phrase has been formerly
in copyleft-next:
https://github.com/richardfontana/copyleft-next/commit/bdd4e3d326ecb0ea674fabdac6d5f8dff3adf575

And later my fork:

Add submissions under later versions.
This is probably unnecessary, but the potential to harm is for
corner cases I guess (I might be wrong). Could review later.

Modify CLA to replace Foundation -> Licensor.
Also a few tweaks to the names, and add warnings.

Give titles to the sections which didn't have one.

Annotate sections.

The warranty section seems compatible with FOSS provisions. (it contains
the term 'conditions' which I don't remember in warranty sections, but
probably that's just me. The intent is clearly to absolve you.)

The obligatory notification section is problematic. I don't really
know how to take it though. Does it clearly break an OSD criterion?
