tests/suites/helpers.function and tests/suites/*_test.function contain
"#line" directives. This causes the TAGS file to contain references
pointing to the file path named in the "#line" directives, which is
relative to the "tests" directory rather than to the toplevel. Fix
this by telling etags to ignore "#line" directives, which is ok since
we aren't actually running it on any generated code.

mbedtls_ssl_conf_dtls_srtp_protection_profiles stores the pointer to the

Some of the material was originally the PSA specification, and
discusses how different implementations might behave. Replace such
statements by a description of how Mbed TLS behaves.

It's about who has access to the key material in plaintext, not directly
where the operation is performed.

These entries were for different aspects of a new, partially implemented
feature. Therefore we are consolidating them into a single entry for
clarity.

Executed ./scripts/bump_version.sh --version 2.25.0 --so-crypto 6
Increasing the SO version of the crypto library, because the openless
API improvement came with API/ABI incompatibilities. For example
- the size of psa_key_handle_t changed
- the type of a parameter in 18 public functions has changed from
psa_key_handle_t to mbedtls_svc_key_id_t

This algorithm replaces the pre-existing stream cipher algorithms.
The underlying stream cipher is determined by the key type.

If a random driver has a built-in entropy source and doesn't need an
external entropy source, make the driver author declare this
explicitly, rather than it being a less secure default.

The get_random entry point was allowed to return partial data on both
PSA_SUCCESS and PSA_ERROR_INSUFFICIENT_ENTROPY, but there was no
meaningful difference between the two. Keep it simple: PSA_SUCCESS is
success but can be partial, and PSA_ERROR_INSUFFICIENT_ENTROPY is an
error with no output.

Explicitly recommend that the driver accounts for environmental
conditions that can affect the amount of entropy.

A random generation driver does not need to support entropy injection.
This will limit it to platforms where the RNG peripheral is the sole
entropy source and without an RNG seed saved into persistent storage.
