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.

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.

Jinja2 rev 2.10.1 is required for the driver wrappers code gen.
The same is set up in the bionic docker file.

The file psa_crypto_driver_wrappers.c is deleted to be autogenerated.
Updated psa_crypto_driver_wrappers.h, this file only contains the
prototypes for the driver wrappers, we don't expect this to be auto
generated.

Change 'tranlation' -> 'translation' in the name of a
method in `scripts/generate_ssl_debug_headers.py`.

Having an automatically generated header file makes it harder to have
working build scripts. The content of ssl_debug_helpers_generated.h isn't
likely to change often, so we can update it manually.

Running `generate_ssl_debug_helpers.py` generates both
`ssl_debug_helpers_generated.c` and `ssl_debug_helpers_generated.h`.
List the `.h` file as well as the `.c` file in `check-generated-files.sh` so
that `check-generated-files.sh -u` will complain if it isn't up to date.
List it in `Makefile` and `CMakeLists.txt` so that parallel builds know when
to wait until the `.h` file is present. In `Makefile`, declare the `.c` file
as depending on the `.h` file for order. This way, a dependency for either
will wait until the `.h` file is present, and since the `.h` file is
generated after the `.c` file, this guarantees that the `.c` file is
present.
This fixes random failures of `make -j` from a fresh checkout.
