598e92991a Rework PSA_AEAD_NONCE_LENGTH to reduce expansion
Due to repeated calls to PSA_AEAD_NONCE_LENGTH, which in turn calls
PSA_ALG_AEAD_WITH_DEFAULT_LENGTH_TAG several times, some macros updated
in this PR expanded to over 6000 characters, more than the 4095 that ISO
C99 compilers are guaranteed to support.

eb1a301321 Update documentation references to the AEAD macros
Where a change was necessary, the new documentation was copied from the
PSA Crypto API spec exactly, with the exception of PSA_AEAD_TAG_LENGTH,
which needed some adjustment.

228abc5773 Define EC curve family constants
Define constants for ECC curve families and DH group families. These
constants have 0x0000 in the lower 16 bits of the key type.

Support these constants in the implementation and in the PSA metadata
tests.

Switch the slot management and secure element driver HAL tests to the
new curve encodings. This requires SE driver code to become slightly
more clever when figuring out the bit-size of an imported EC key since
it now needs to take the data size into account.

Switch some documentation to the new encodings.

Remove the macro PSA_ECC_CURVE_BITS which can no longer be implemented.

025fccdc32 Change the encoding of EC curves and DH groups to include the size
Change the representation of psa_ecc_curve_t and psa_dh_group_t from
the IETF 16-bit encoding to a custom 24-bit encoding where the upper 8
bits represent a curve family and the lower 16 bits are the key size
in bits. Families are based on naming and mathematical similarity,
with sufficiently precise families that no two curves in a family have
the same bit size (for example SECP-R1 and SECP-R2 are two different
families).

As a consequence, the lower 16 bits of a key type value are always
either the key size or 0.

72c8c5b352 Merge remote-tracking branch 'upstream-crypto/development' into psa-api-1.0-beta-merge_development_20190801
Conflict resolution:
* `scripts/config.pl`:
  Take the exclusion of `MBEDTLS_PSA_CRYPTO_SE_C` from the API branch.
  Take the removal of `MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C` (obsolete) from
  the development branch.
* `tests/scripts/all.sh`:
  Multiple instances of factoring a sequence of `config.pl` calls into
  a mere `config.pl baremetal` in the development branch, and a change in
  the composition of `baremetal` in the API branch. In each case, take the
  version from development.
* `tests/suites/test_suite_psa_crypto_slot_management.function`:
  A function became non-static in development and disappeared in the API
  branch. Keep the version from the API branch. Functions need to be
  non-static if they're defined but unused in some configurations,
  which is not the case for any function in this file at the moment.
* `tests/suites/test_suite_psa_crypto.function`:
  Consecutive changes in the two branches, reconciled.

d58a00d5b7 psa: Avoid use of relative include paths
Relative include paths should be avoided. The build system will
determine where to pull in includes from. Specifically, `#include
"../mbedtls/config.h"` shouldn't be used. Use `#include
"mbedtls/config.h` instead, so that the submodule-building makefiles can
change which directory to use to get mbedtls include files from.

Fixes #141

56e2dc8010 Use "sufficient buffer size" in buffer size macros
Don't use "safe buffer size", because this it's somewhat misleading to
make it about safety: a buffer size that's too small will lead to a
runtime error, not to undefined behavior.

24f10f85e2 Remove domain parameters from the official API
Move psa_get_key_domain_parameters() and
psa_set_key_domain_parameters() out of the official API and declare
them to be implementation-specific extensions.

Expand the documentation of psa_set_key_domain_parameters() a bit to
explain how domain parameters are used.

Remove all mentions of domain parameters from the documentation of API
functions. This leaves DH and DSA effectively unusable.
