2e22ecbd09 Add guide to implementing new cryptographic mechanisms 
Add a check list with what typically needs to be done when adding a new
algorithm, key type or operation. There are a few explanations but this is
primarily intended as a list of places to look and not as a detailed
explanation of exactly what to do.

41618da50e Clarify backward compatibility requirement 
There are two somewhat distinct aspects here: if it compiled, it still
compiles; and if it worked functionally, it still works. They're related in
that if application code currently compiles but cannot possibly work, we
could reasonably make it not compile anymore.

335cbf61da Remove temporary documents 
The dependencies-xxx.md documents where merely a support for study,
now distilled to strategy.md, psa-limitation.md, and tasks-xx.md
and/or github issues.

The tasks-g1.md document has now been fully converted to a list of
github issues.

These documents would quickly become out-of-date and there's little
point in updating them, so it's better to remove them. They're still in
the github history if anyone wants to have a look.

220bda7f76 Rename a function parameter to avoid confusion 
Don't use “output” for an input of the KDF. It's correct in context (it's
the output of a function that copies the input of the KDF from core-owned
memory to driver-owned memory) but confusing.

a2b41598d6 Draft specification for key derivation 
Pass all the initial inputs in a single structure. It's impossible to pass
the inputs as soon as the application makes them available because the core
cannot know which driver to call until it receives the SECRET input.

Do support hiding the key material inside a secure element if the relevant
driver has all the requisite entry points.

Do cooked key derivation (i.e. derivation of non-raw keys) and key agreement
separately.
