8bb96d96cd Fix buffer size calculation 
Make sure that buf always has enough room for what it will contain. Before,
this was not the case if the buffer was smaller than the default response,
leading to memory corruption in ssl_server2.

51a7679a8e Ensure context is passed in to dummy_rand 
In fuzz_privkey, we switched over to using dummy_rand(), which uses
ctr_drbg internally, and thus requires an initialised ctr_drbg_context
to be passed in via p_rng when calling mbedtls_pk_parse_key().

00738bf65e Ensure ctr_drbg is initialised every time 
ctr_drbg is a local variable and thus needs initialisation every time
LLVMFuzzerTestOneInput() is called, the rest of the variables inside the
if(initialised) block are all static.

Add extra validation to attempt to catch this issue in future.

c82504e22c Clean up output from cipher_aead_demo

had both cipher and PSA. Now it doesn't really make sense. Align the
output to match the PSA version of this program.
