Document the return value of mbedtls_ecdsa_raw_to_der() and
mbedtls_ecdsa_der_to_raw().
Document that mbedtls_ecdsa_raw_to_der() has undefined behavior when the
output buffer parameter is null, even with a size of 0.

mbedtls-3.6 branch misses some crypto client changes that has
been done in the development branch since the LTS release. Therefore
CRYPTO_C guard here is more accurate than CRYPTO_CLIENT.
- entropy.h
In the development branch MBEDTLS_ENTROPY_BLOCK_SIZE is defined
when PSA_WANT_ALG_SHA_[256/512] is defined while in the mbedtls-3.6
branch is guarded by MBEDTLS_MD_CAN_SHA[256/512] which is slightly
different. Since MBEDTLS_ENTROPY_BLOCK_SIZE is used in some tests's
data files, we need to have it defined also if the related test
is skipped. Therefore we add the PSA_WANT_ALG_SHA conditions together
with the MBEDTLS_MD_CAN_SHA ones to mimic the development behavior.

This helps reducing heap memory usage and, if heap memory is
not used anywhere else in an embedded device, it also reduces
code footprint since there is no need for heap management code
in this case.
A new build symbol is added for this purpose, named
MBEDTLS_PSA_STATIC_KEY_SLOTS. It's disabled by default so that
normal usage of Mbed TLS library is not affected.

Move MBEDTLS_ERR_SSL_RECEIVED_NEW_SESSION_TICKET
error code documentation to the documentation of

descriptions because of a limitation in

Add mbedtls_ssl_conf_enable_new_session_tickets() API
to be able to enable and disable the handling of TLS 1.3
NewSessionTicket messages.
The TLS 1.2 equivalent function is named
mbedtls_ssl_conf_session_tickets() thus the most
natural name would have been
mbedtls_ssl_conf_new_session_tickets() but it is
already used on server side thus rather
mbedtls_ssl_conf_enable_new_session_tickets().

For backward compatibility with Mbed TLS <=3.5.x, applications must be able
to make a TLS connection with a peer that supports both TLS 1.2 and TLS 1.3,
regardless of whether they call psa_crypto_init(). Since Mbed TLS 3.6.0,
we enable TLS 1.3 in the default configuration, so we must take care of
calling psa_crypto_init() if needed. This is a change from TLS 1.3 in
previous versions, where enabling MBEDTLS_SSL_PROTO_TLS1_3 was a user
choice and could have additional requirement.
This commit removes the compatibility-breaking requirement from the
documentation.

These macros are not part of any public or internal API, ideally they
would be defined in the source files. The reason to put them in
bignum_core.h to avoid duplication as macros for this purpose are
needed in both bignum.c and bignum_core.c.

The complexity of having functions whose security properties depend on a
runtime argument can be dangerous. Limit misuse by making any such
functions local.

Create a new compilation option for a dynamically resized key store. The
implementation will follow in subsequent commits.
This option is off by default with custom configuration files, which is best
for typical deployments on highly constrained platforms. This option is on
by default with the provided configuration file, which is best for typical

MBEDTLS_PSA_HMAC_DRBG_MD_TYPE was documented and announced as causing the
PSA DRBG to be HMAC_DRBG. However, that was never actually implemented:
CTR_DRBG is prioritized if enabled.
Since there is a simple workaround of disabling MBEDTLS_CTR_DRBG_C if you
want to use HMAC_DRBG, we have decided to accept the actual behavior and fix
the documentation.

The description was misleading: setting the option doesn't “restrict” the
number of slots, that restriction exists anyway. Setting the option merely
determines the value of the limit.

Make it possible, but not officially supported, to switch the CTR_DRBG
module to PSA mode even if MBEDTLS_AES_C is defined. This is not really
useful in practice, but is convenient to test the PSA mode without setting
up drivers.
