- Applied the patch in `thirdparty/mbedtls/patches/1453.diff` (PR 1453).
Soon to be merged upstream. Check it out at next update.
-- Applied the patch in `thirdparty/mbedtls/patches/padlock.diff`. This disables VIA
- padlock support which defines a symbol `unsupported` which clashes with
- a symbol in libwebsockets.
- Added 2 files `godot_core_mbedtls_platform.{c,h}` providing configuration
for light bundling with core.
