6d576c9646 Call setbuf when reading or writing files: programs 
After opening a file containing sensitive data, call mbedtls_setbuf() to
disable buffering. This way, we don't expose sensitive data to a memory
disclosure vulnerability in a buffer outside our control.

This commit adds a call to mbedtls_setbuf() after each call to fopen(),
but only in sample programs that were calling mbedtls_platform_zeroize().
Don't bother protecting stdio buffers in programs where application buffers
weren't protected.

0ff241a1ea Remove largely useless bit of test log to silence GCC 12 
GCC 12 emits a warning because it thinks `buffer1` is used after having been
freed. The code is correct C because we're only using the value of
`(uintptr_t)buffer1`, not `buffer1`. However, we aren't using the value for
anything useful: it doesn't really matter if an alloc-free-alloc sequence
returns the same address twice. So don't print that bit of information, and
this way we don't need to save the old address.

Fixes #5974.

certificate chains exposing an RSA key with

f071024bf8 Do not include time.h without MBEDTLS_HAVE_TIME 
MBEDTLS_HAVE_TIME is documented as: "System has time.h and time()."

If that is not defined, do not attempt to include time.h.

A particular problem is platform-time.h, which should only be included if
MBEDTLS_HAVE_TIME is defined, which makes everything messier. Maybe it
should be refactored to have the check inside the header.

A valid ctr_drbg context is now a prerequisite for using dummy_random()

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.
