4f4af6e2ef windows: Fix Release x64 configuration
Inherit PlatformToolset from the project configuration. This allow the
project to configure PlatformToolset, and aligns the Release x64 build
with other build types.

a4308b29a4 Remove unused TLS, NET, and X.509 files
We've removed all software that depends on or uses the TLS, NET, and
X.509 modules. This means TLS, NET, and X.509 are unused and can be
removed. Remove TLS, NET, and X.509.

21cb3c34a3 Remove ssl_cert_test sample app
Remove the ssl_cert_test sample application, as it uses
hardcoded certificates that moved, and is redundant with the x509

5e80d91dbf Remove psa_crypto_storage_backend.h
Since there is now a single storage backend, we don't need a backend
interface. Make the functions that were declared in
psa_crypto_storage_backend.h and are now both defined and used in
psa_crypto_storage.c static, except for psa_is_key_present_in_storage
which is used by the gray-box tests and is now declared in
psa_crypto_storage.h.

088b77f39c Merge psa_crypto_storage_its into psa_crypto_storage
Since the ITS API has stabilized and we don't plan to make use of more
than ITS, we don't need an abstraction layer between key storage and
key storage over ITS. Merge the ITS code into the generic storage
module.

e435f23019 Remove psa_crypto_storage_file
Now that we have ITS over files, we no longer need a direct backend
for key storage over files. Remove psa_crypto_storage_file and its
tests.

Switch MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C and MBEDTLS_PSA_ITS_FILE_C on
by default. This preserves functionality and test coverage in the
default configuration, but forgets any key previously stored using the
file backend.

601bd53b80 Fix up ITS header files for internal use in crypto
Merge storage_common.h and internal_trusted_storage.h into a single
file for convenience.

Remove #include of <psa/error.h> which crypto doesn't have yet and
include <psa/crypto_types.h> and <psa/crypto_values.h> instead.

Drop __cplusplus support which we don't need.

Tweak style (whitespace, line breaks, comment formatting) to satisfy
check-names.sh and check-files.sh.

03c60de0e0 query_config: Move to programs/test
As the SSL programs, like ssl_client2 and ssl_server2, are dependent on
SSL and therefore about to be removed, the only consumer of query_config
is the query_compile_time_config test. As such, it makes sense to move
query_config to be next to what uses it.

bea98b4581 Remove Diffie-Hellman examples
These examples rely on the NET module, which we want to remove. In
theory we could remove just the dependency, but we decided to remove the
whole example because:

 - They showcase some bad crypto: custom, undocumented protocol (not
   obviously broken though, apart from authenticating only one side);
   hard-coded limit of 512-bit size for the DH modulus (2048 is the
   recommended minimum these days); direct use of the shared secret as a
   key (instead of applying a KDF); encryption with ECB, custom
   parameters and the client not having the ability to verify them.
 - The programs use the DH API in the same way that TLS does, so they
   have limited demonstration value.
 - The programs only show finite-field DH, which is not used all that
   much these days. What people want to see is mostly ECDH.

75976895c6 Split crypto_driver.h into one for each driver type
Split crypto_driver.h into 4:
* crypto_driver_common.h for common definitions, not meant to be
  included directly by driver code.
* crypto_accel_driver.h for drivers that work with transparent
  key material.
* crypto_se_driver.h for drivers that work with opaque key
  material.
* crypto_entropy_driver.h for drivers of entropy sources.

There is no code change in this commit, I only moved some code around.

f3b731e817 Move integral types and associated macros to their own header
Some parts of the library, and crypto drivers, need to see key types,
algorithms, policies, etc. but not API functions. Move portable
integral types and macros to build and analyze values of these types
to a separate headers crypto_types.h and crypto_values.h.

No functional changes, code was only moved from crypto.h to the new headers.

961849f6d1 Implement slot allocation
Implement psa_allocate_key, psa_open_key, psa_create_key,
psa_close_key.

Add support for keys designated to handles to psa_get_key_slot, and
thereby to the whole API.

Allocated and non-allocated keys can coexist. This is a temporary
stage in order to transition from the use of direct slot numbers to
allocated handles only. Once all the tests and sample programs have
been migrated to use handles, the implementation will be simplified
and made more robust with support for handles only.

db2b8db715 psa: Add storage implementation for files
Add new functions, psa_load_persistent_key(),
psa_free_persistent_key_data(), and psa_save_persistent_key(), for
managing persistent keys. These functions load to or save from our
internal representation of key slots. Serialization is a concern of the
storage backend implementation and doesn't abstraction-leak into the
lifetime management code.

An initial implementation for files is provided. Additional storage
backends can implement this interface for other storage types.

dca3a5d884 Rename aead_chacha20_poly1305 to chachapoly
While the old name is explicit and aligned with the RFC, it's also very long,
so with the mbedtls_ prefix prepended we get a 31-char prefix to each
identifier, which quickly conflicts with our 80-column policy.

The new name is shorter, it's what a lot of people use when speaking about
that construction anyway, and hopefully should not introduce confusion at
it seems unlikely that variants other than 20/1305 be standardised in the
foreseeable future.
