PR #3959 has proven that by adding a prefix
(LIBTESTDRIVER1/libtestdriver1_ in this commit) to
all MBEDTLS/PSA_* and mbedtls/psa_* symbols of a copy
of the Mbed TLS library, we can build a library that
can be linked with the Mbed TLS library.
This commit leverages this to build a PSA test driver
library based on the Mbed TLS library code.
The cryptographic features supported by the test
library are defined by:
. a minimal configuration (in the sense of config.h),
see config_test_driver.h
. PSA_WANT_* and PSA_ACCEL_* defined macros.
The PSA_WANT_* macros have to be the same as the ones
used to build the Mbed TLS library the test driver
library is supposed to be linked to as the PSA_WANT_*
macros are used in the definition of structures and
macros that are shared by the PSA crypto core,
Mbed TLS drivers and the driver test library.
The PSA_ACCEL_* macros are intended to define the
cryptographic features that have to be removed
from the Mbed TLS library and thus supported by the
test library in test scenarios. The PSA_ACCEL_* macros
to build the test library are thus mirrored from the
ones to build the Mbed TLS library by extended the
crypto_config.h: see
crypto_config_test_driver_entension.h.

Modeled after the include chain of the primitive operation contexts.
Also moved the HMAC context structure to the builtin composites file,
since that is where it conceptually belongs. This is a preparatory
step for implementing driver dispatch of MAC multipart operations.

This is a preparatory step in order to be able to organize the include
chain from crypto_struct in such a way that the MAC operation structure
for the PSA 'software' driver can make use of the hash operation structure.
Conceptually:
* Primitives:
* Hash
* Cipher
* Composites:
* AEAD (can use cipher)
* MAC (can use cipher and/or hash)

MSVC doesn't like multiple compilation units with the same name.

This header file will contain declarations of functions that are not
part of the public ABI/API, and must not be called from other modules,
but can be called from unit tests.

Drivers (both built-in and external) need to declare their context
structures in a way such that they are accessible by the
to-be-autogenerated crypto_driver_contexts.h file. That file lives in
include/psa, which means all builtin driver context structure
declarations also need to live in include/psa.

Apparently there's a goal to make the PSA Crypto core free from
dynamic memory allocations. Therefore, all driver context structures
need to be known at compile time in order for the core to know their
final size.
This change defines & implements for hashing operations how the context
structures get defined.

When using pthread mutexes (MBEDTLS_THREADING_C and
MBEDTLS_THREADING_PTHREAD enabled), and when test hooks are
enabled (MBEDTLS_TEST_HOOKS), set up wrappers around the
mbedtls_mutex_xxx abstraction. In this commit, the wrapper functions
don't do anything yet.

Move the declaration of the functions needed to use the test
implementation of mbedtls_psa_external_get_random() to a new header
file. Before, they were declared in
tests/include/test/psa_crypto_helpers.h, but this header file can't be
included in sample programs because it also includes headers from the
library directory which is not on the include path for sample
programs.
This fixes the build of the sample programs when
MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG and MBEDTLS_USE_PSA_CRYPTO are
enabled.
Move the implementation of the functions to a separate .c file as
well. This isn't strictly necessary, but makes the structure of the
source code easier to understand.

Make it clear that this is an abstraction of the random generator
abstraction, and not an abstraction of the PSA random generator.
mbedtls_psa_get_random and MBEDTLS_PSA_RANDOM_STATE are public-facing
definitions and will be moved in a subsequent commit.

The driver interfaces described in crypto_accel_driver.h and
crypto_entropy_driver.h are no longer being worked on. We do not
intend to finish the design of these interfaces or to implement them
in Mbed TLS. They have been superseded by the unified driver
interface (docs/proposed/psa-driver-interface.md), which is being
actively worked on both to finalize the specification and to implement
it in Mbed TLS.
The partially implemented dynamic secure element interface is staying
for now.

Moved from doing the dependency checks for MBEDTLS_PSA_BUILTIN to

This commit introduces a new file library/ssl_tls13_key.c
which will subsequently be populated with functionality relating
to the TLS 1.3 key schedule.
Those functions are expected to be internal and are documented
in the internal header library/ssl_tls13_keys.h.
The first function to be implemented is the key expansion
function `HKDF-Expand-Label`. See the documentation in
library/ssl_tls13_keys.h for more information.
