8ff510ac26 Rename ECC Family Macros According to PSA Spec
Rename PSA_ECC_CURVE_xxx to PSA_ECC_FAMILY_xxx, also rename
PSA_KEY_TYPE_GET_CURVE to PSA_KEY_TYPE_ECC_GET_FAMILY and rename
psa_ecc_curve_t to psa_ecc_family_t. Old defines are provided in
include/crypto_compat.h for backward compatibility.

700ee44545 Add missing copyright dates to scripts and sources
To find any files with a missing copyright declaration, use the following script:

# ========================
#!/bin/sh

# Find files with copyright declarations, and list their file extensions
exts=$(grep -Ril --exclude-dir .git --exclude-dir 3rdparty\
                 --exclude-dir programs/fuzz 'Copyright.*Arm' | sed '
  s/.*\///
  s/.*\./*./
  s/.*/-name "&"/
' | sort -u | sed -n '
  :l
    N
    $!bl
  s/\n/ -o /gp
')

# Find files with file extensions that ususally include copyright extensions,
# but don't include a copyright declaration themselves.
eval "find\
  '(' -path './.git' -o -path './3rdparty' -o -path './programs/fuzz' ')' -prune\
  -o ! -path './tests/data_files/format_pkcs12.fmt'\
     ! -path './programs/psa/psa_constant_names_generated.c'\
     '(' $exts ')' -print" | xargs grep -Li 'Copyright.*Arm'

f65ed6f254 Change key types to a 16-bit encoding
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.

dcaefae849 Parametrize Diffie-Hellman keys by a group identifier
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.

3f775264d3 psa_constant_names: adding support for signed types
psa_constant_names now works correctly with signed values, such as
psa_status_t may have.

1b879843d1 psa_constant_names: factor unsigned support into its own function
This is in preparation for adding support for signed types (namely,
psa_status_t).

265a171c52 Error out if a value is out of range
psa_status_t is currently a signed type where only non-negative values
are used, which makes things a bit awkward. For now, non-negative
values trigger an error. This code will need to be revised if we
switch to using negative values as error codes.

608e091d9a Add pre Visual Studio 2015 support to psa_constant_names
snprintf was only added in Visual Studio 2015. This adds support
for building using Visual Studio versions prior to 2015.

This implementation of snprintf has been taken from platform.c

029b5d648d New utility program psa/psa_constant_names
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.
