Security
* Support calling PSA functions with buffer arguments that are in memory
shared with an untrusted party. The PSA core now makes copies of all
buffers before passing them to drivers to protect drivers against
modification of buffers during operations.
This feature increases code-size and memory usage. If buffers passed to
PSA functions are all trusted, buffer copying may be disabled by
unsetting MBEDTLS_PSA_COPY_CALLER_BUFFERS.
