mbedtls/CMakeLists.txt
Jaeden Amero 8dd1690993 Merge remote-tracking branch 'tls/development' into development 
Resolve conflicts by performing the following operations:
- Reject changes related to building a crypto submodule, since Mbed
  Crypto is the crypto submodule.
- Reject X.509, NET, and SSL changes.
- Reject changes to README, as Mbed Crypto is a different project from
  Mbed TLS, with a different README.
- Avoid adding mention of ssl-opt.sh in a comment near some modified
  code in include/CMakeLists.txt (around where ENABLE_TESTING as added).
- Align config.pl in Mbed TLS with config.pl in Mbed Crypto where PSA
  options are concerned, to make future merging easier. There is no
  reason for the two to be different in this regard, now that Mbed TLS
  always depends on Mbed Crypto. Remaining differences are only the
  PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER option and the absence of X.509,
  NET, and SSL related options in Mbed Crypto's config.pl.
- Align config.h in Mbed Crypto with Mbed TLS's copy, with a few notable
  exceptions:
  - Leave CMAC on by default.
  - Leave storage on by default (including ITS emulation).
  - Avoid documenting the PSA Crypto API as is in beta stage in
    documentation for MBEDTLS_PSA_CRYPTO_C.
  The only remaining differences are a lack of X.509, NET, and SSL
  options in Mbed Crypto's config.h, as well as an additional
  Mbed-Crypto-specific PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER option.
  Documentation for the check params feature and related macros is also
  updated to match Mbed TLS's description.
- Reject tests/data_files/Makefile changes to generate DER versions of
  CRTs and keys, as none of those are used by Mbed Crypto tests.
- Add the "no PEM and no filesystem" test to all.sh, without ssl-opt.sh
  run, as Mbed Crypto doesn't have ssl-opt.sh. Also remove use of PSA
  Crypto storage and ITS emulation, since those depend on filesystem
  support.
- Reject addition of test when no ciphersuites have MAC to all.sh, as
  the option being tested, MBEDTLS_SSL_SOME_MODES_USE_MAC, is not
  present in Mbed Crypto.
- Use baremetal config in all.sh, as Mbed Crypto's baremetal
  configuration does exclude the net module (as it doesn't exist in Mbed
  Crypto)
- Reject cmake_subproject_build changes, continuing to link only
  libmbedcrypto.
- Reject changes to visualc and associated templates. Mbed Crypto
  doesn't need additional logic to handle submodule-sourced headers.
- Avoid adding fuzzers from Mbed TLS. The only relevant fuzzers are the
  privkey and pubkey fuzzers, but non-trivial work would be required to
  integrate those into Mbed Crypto (more than is comfortable in a merge
  commit).
- Reject addition of Docker wrappers for compat.sh and ssl-opt.sh, as
  those are not present in Mbed Crypto.
- Remove calls to SSL-related scripts from basic-in-docker.sh

Fix test errors by performing the following:
- Avoid using a link that Doxygen can't seem to resolve in Mbed Crypto,
  but can resolve in Mbed TLS. In documentation for
  MBEDTLS_CHECK_PARAMS, don't attempt to link to MBEDTLS_PARAM_FAILED.
