ff43ff6e78 Remove stability waiver from USE_PSA 
It was initially motivated by the fact that the PSA Crypto APIs
themselves were not stable. In the meantime, PSA Crypto has reached
1.0.0 so this no longer applies.

If we want user to be able to fully benefit from PSA in order to
isolate long-term secrets, they need to be able to use the new APIs with
confidence. There is no reason to think those APIs are any more likely
to change than any of our other APIs, and if they do, we'll follow the
normal process (deprecated in favour of a new variant).

For reference, the APIs in question are:

mbedtls_pk_setup_opaque() // to use PSA-held ECDSA/RSA keys in TLS

mbedtls_ssl_conf_psk_opaque()   // for PSA-held PSKs in TLS
mbedtls_ssl_set_hs_psk_opaque() // for PSA-held PSKs in TLS

mbedtls_cipher_setup_psa() (deprecated in 3.2)
mbedtls_pk_wrap_as_opaque() (documented internal, to be removed in 3.2)

54eb0686b3 New function psa_crypto_driver_key_derivation_get_input_type 
The new function psa_crypto_driver_key_derivation_get_input_type() allows
drivers to retrieve the effective type of each input step, and thus to call
the correct get-data function. This is simpler than the previous scheme
which required a somewhat contrived dance with get_key() and get_bytes() for
inputs that can be passed either as a key or as a byte buffer at the
application's choice.

We hadn't updated the storage specification in a while. There have been no
changes to the storage layout, but the details of the contents of some

describe it fully, avoiding references to previous versions.

1b52d09494 Document test strategy for USE_PSA_CRYPTO 
Note: removed `mbedtls_x509write_crt_set_subject_key()` from the list of
things that should be tested, as it's taking public key rather than a
keypair.

0d0a104b2d Add study for TLS/X.509 dependencies on crypto 
This is an updated version of the study that was done a few years ago.

The script `syms` was used to list symbols form libmbedtls.a /
libmbedx509.a that are defined externally. It was run with config.py
full minus MBEDTLS_USE_PSA_CRYPTO minus
MBEDTLS_SSL_PROTO_TLS1_3_EXPERIMENTAL.

66491c7d08 Edit docs to explain not changing curve order 
TLS1.3 MVP would benefit from a different curve group preference order
in order to not cause a HelloRetryRequest (which are not yet handled),
however changing the curve group preference order would affect both
TLS1.2 and TLS1.3, which is undesirable for something rare that can
be worked around.

Also, remove the section about design considerations for now. It's

include considerations about possible paths for the future, which would
better be separated from user documentation (separating the certain that
is now, from the uncertain that might or might not be later).

The import-and-save and load-and-check parts of the tests don't have to be

Introduce the terms “forward compatibility” and “backward compatibility” and
relate them to import-and-save and load-and-check actions.

These are clarifications of intent that do not represent an intended change
in the strategy or intended coverage.

f00f152444 Add output size parameter to signature functions 
The functions mbedtls_pk_sign(), mbedtls_pk_sign_restartable(),
mbedtls_ecdsa_write_signature() and mbedtls_ecdsa_write_signature_restartable()
now take an extra parameter indicating the size of the output buffer for the
signature.

No change to RSA because for RSA, the output size is trivial to calculate.

39957503c5 Remove secp256k1 from the default X.509 and TLS profiles 
For TLS, secp256k1 is deprecated by RFC 8422 §5.1.1. For X.509,
secp256k1 is not deprecated, but it isn't used in practice, especially
in the context of TLS where there isn't much point in having an X.509
certificate which most peers do not support. So remove it from the
default profile. We can add it back later if there is demand.

Meld the migration guide for the removal of
MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_CERTIFICATES into the migration guide for
the strengthening of TLS and X.509 defaults, which is more general. The
information in the SHA-1 section was largely already present in the
strengthening section. It is now less straightforward to figure out how to
enable SHA-1 in certificates, but that's a good thing, since no one should
still be doing this in 2021.

b1940a76ad In TLS, order curves by resource usage, not size 
TLS used to prefer larger curves, under the idea that a larger curve has a
higher security strength and is therefore harder to attack. However, brute
force attacks are not a practical concern, so this was not particularly
meaningful. If a curve is considered secure enough to be allowed, then we
might as well use it.

So order curves by resource usage. The exact definition of what this means
is purposefully left open. It may include criteria such as performance and
memory usage. Risk of side channels could be a factor as well, although it
didn't affect the current choice.

The current list happens to exactly correspond to the numbers reported by
one run of the benchmark program for "full handshake/s" on my machine.

6a2fb61896 Rename library/ecp_alt.h to ecp_internal_alt.h 
library/ecp_alt.h (declaring individual functions of the ECP module that can
be substituted, included when building the library with
MBEDTLS_ECP_INTERNAL_ALT enabled) clashes with ecp_alt.h (not provided,
declaring types of the ECP module when the whole implementation is
substituted, included when building the library with MBEDTLS_ECP_ALT enabled).
Depending on the search path during build, this can make MBEDTLS_ECP_ALT
unusable.

Rename library/ecp_alt.h to follow the naming convention of other alt headers:
MBEDTLS_XXX_ALT corresponds to xxx_alt.h.
