Keep module compatibility with mbedtls 2.x (old LTS branch).
A patch has been added to allow compiling after removing all the `psa_*`
files from the library folder (will look into upstreaming it).
Note: mbedTLS 3.6 finally enabled TLSv1.3 by default, but it requires
some module changes, and to enable PSA crypto (new "standard" API
specification), so it might be best done in a separate commit/PR.
We had a slightly older version of it for UWP, as the wincrypt API isn't allowed there.
We removed this with UWP in #81416, but since this was enabled inconditionally before,
this actually changed behavior for Windows compared to Godot 4.1 and earlier.
This change is also needed to properly supported Windows Store.
The UWP platform port was never ported to the Godot 4.0+ API,
and it's now accumulating bitrot as it doesn't compile, and thus
we no longer propagate platform changes in it.
So we finally remove to acknowledge this state. There's still some
interest in reviving the UWP port eventually, especially as support
for Direct3D 12 will soon be merged, but when that happens it will
be easiest to redo it from scratch.
Keep applying the windows entropy patch (UWP support).
Remove no longer needed padlock patch.
Update thirdparty README to reflect changes, and new source inclusion
criteria.
For some weird reason 'git apply' does not error out when it does nothing,
so I missed that I did not apply the patch properly in #36823...
This broke the UWP 32-bit x86 build.
Fixes CVE-2019-18222.
`include/mbedtls/version.h` was modified to include the forgotten
version bump to 2.16.4, fixed upstream by ARMmbed/mbedtls#2992.
Godot core needs MD5/SHA256/AES/Base64 which used to be provided by
separate libraries.
Since we bundle mbedtls in most cases, and we can easily only include
the needed sources if we so desire, let's use it.
To simplify library changes in the future, and better isolate header
dependencies all functions have been wrapped around inside a class in
`core/math/crypto_base.h`.
If the mbedtls module is disabled, we only bundle the needed source
files independently of the `builtin_mbedtls` option.
If the module is enabled, the `builtin_mbedtls` option works as usual.
Also remove some unused headers from StreamPeerMbedTLS which were
causing build issues.
