By default, exclude macros whose numerical value is not a valid member
of the semantic type (e.g. PSA_ALG_xxx_BASE is not itself an
algorithm, only an intermediate value used to construct others). But
do include them with include_intermediate=True, which
generate_psa_constants.py does.

Python should not be required for the build when the no_test target is
used. This commit adds the generated file to the source tree and the
check-generated-files script, and removes the generation from (c)make.
Fixes#3524

As a result, the copyright of contributors other than Arm is now
acknowledged, and the years of publishing are no longer tracked in the
source files.
Also remove the now-redundant lines declaring that the files are part of
MbedTLS.

This commit modifies the generate_psa_constants.py script to take as
input argument the location of where to write the
psa_constant_names_generated.c file.
For make-based build system, this commit does not change anything.
For CMake build system, this commit modifies the generation location of
that file to be inside the build directory and include it from there in
psa_constant_names.c

All key types now have an encoding on 32 bits where the bottom 16 bits
are zero. Change to using 16 bits only.
Keep 32 bits for key types in storage, but move the significant
half-word from the top to the bottom.
Likewise, change EC curve and DH group families from 32 bits out of
which the top 8 and bottom 16 bits are zero, to 8 bits only.
Reorder psa_core_key_attributes_t to avoid padding.
Filter out non-ASCII characters in automatically processed headers.
Do this in a way that minimizes the code change: keep manipulating
strings, but strip off non-ASCII characters when reading lines, which
should only remove characters in comments that we don't parse anyway.
Use PEP 257 indented docstring style, mostly: always with """, with the
terminating """ on a separate line if the docstring is more than one
line, and with all lines indented to the opening """.
This commit does not change the text to keep the first paragraph single-line.
* Rename internal methods and fields to start with an underscore.
* Rename global constants to uppercase.
* Change methods that don't use self to be class methods or static
methods as appropriate.
No behavior change in this commit.
Parametrize finite-field Diffie-Hellman key types with a DH group
identifier, in the same way elliptic curve keys are parametrized with
an EC curve identifier.
Define the DH groups from the TLS registry (these are the groups from
RFC 7919).
Replicate the macro definitions and the metadata tests from elliptic
curve identifiers to DH group identifiers.
Define PSA_DH_GROUP_CUSTOM as an implementation-specific extension for
which domain parameters are used to specify the group.
test_psa_constant_names.py was originally written before the split of
crypto.h into crypto_values.h and more, so it now needs to read
crypto_values.h as well.
In both generate_psa_constants.py and test_psa_constant_names.py, read
crypto_extra.h as well. We don't currently define any value there, but
it's plausible that we will one day.
Some parts of the library, and crypto drivers, need to see key types,
algorithms, policies, etc. but not API functions. Move portable
integral types and macros to build and analyze values of these types
to a separate headers crypto_types.h and crypto_values.h.
No functional changes, code was only moved from crypto.h to the new headers.
OFB and CFB are streaming modes. XTS is a not a cipher mode but it
doesn't use a separate padding step. This leaves only CBC as a block
cipher mode that needs a padding step.
Since CBC is the only mode that uses a separate padding step, and is
likely to remain the only mode in the future, encode the padding mode
directly in the algorithm constant, rather than building up an
algorithm value from a chaining mode and a padding mode. This greatly
simplifies the interface as well as some parts of the implementation.
Print the symbolic name corresponding to a numerical value.
Supported types: status values, algorithms, elliptic curves,
key types, key usage masks.
The program is partly generated from parsing psa/crypto.h with a few
hard-coded assumptions. This isn't ideal but it works and requires
little machinery.
