Not all of the writes to this field are protected by a mutex.
There is no also no protection in place to stop another thread from overwriting
the current transaction

The endpoint and version were factorized out into the main session.
Update the session struct comment to reflect these new fields, as was
previously missed.

Add config bits for server name indication, early data and record size
limit, which all cause the serialized session to be structured
differently.

This config option decides whether the session stores the entire
certificate or just a digest of it, but was missing from the
serialization config bitflag.

Having a non-const `key` parameter was anotherf defect of
mbedtls_ecp_write_key(). Take this opportunity to fix it.
Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>
Same as mbedtls_ecp_write_key(), but doesn't require the caller to figure out
the length of the output and possibly distinguish between Weierstrass and
Montgomery curves.

This commit also fixes pk_psa_wrap_sign_ext() setting the RSA padding
mode so that mbedtls_pk_get_psa_attributes() correctly guesses
the PSA alg to be used.

The `flags` field in `psa_key_attributes_t` was a general mechanism that
only ever got used for a single flag: to indicate that the `slot_number`
field has been set. We have switched to a dedicated indicator for that, so
we can now remove `flags`.
Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>
In `psa_key_attributes_t`, keep track of whether `slot_number` has been set
through a dedicated field, rather than using a flag.
This paves the way to removing `flags`, which is not used for anything else.

The `psa_core_key_attributes_t` structure is no longer used. Remove it.
Switch `psa_key_attributes_t` back to a simple struct, now containing
the fields that were formerly inside its `psa_core_key_attributes_t core`
member. This repairs the build with non-C11 compilers.

Access the fields of `psa_key_attributes_t` directly rather than through the
`core` field. This makes the `core` field obsolete.
This commit is fully automated:

Now that a key slot contains the full `psa_key_attributes_t, the temporary
local variables holding a copy of core attributes read from the slot are no
longer needed.

Switch `psa_key_slot_t` to the full `psa_key_attributes_t`, now that this
structure only has psa_core_key_attributes_t`.
To minimize the diff without breaking the build much, temporarily make
`psa_key_attributes_t` contain either the `core` field or all the fields.
This allows both things like `slot->attr.core.type` and `slot->attr.type`
to exist. The build breaks with compilers that don't support anonymous
unions and structs, which are only standard C since C11.

Move the `slot_number` field of `psa_key_attributes_t` to
`psa_core_key_attributes_t`. This makes ``psa_core_key_attributes_t` core`
the sole field of `psa_key_attributes_t`. This paves the way to unifying
the two structures.
