This commit modifies programs/test/selftest to include a check that
none of the standard integer types (unsigned) [short, int, long, long]
uses padding bits, which we currently don't support.

time() is only needed to seed the PRNG non-deterministically. If it isn't
available, do seed it, but pick a static seed.

The added null byte was accounted for twice, once by taking
opt.buffer_size+1 when allocating the buffer and once by taking opt.buffer-1
when filling the buffer. Make opt.buffer_size the size that is actually
read, it's less confusing that way.

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.

MBEDTLS_HAVE_TIME_ALT implies MBEDTLS_HAVE_TIME, so an extra
check for MBEDTLS_HAVE_TIME is not needed.

Remove direct inclusion of mbedtls_config.h and replace with
build_info.h, as is the convention in Mbed TLS 3.0.

Allow programs/test/udp_proxy.c to build when MBEDTLS_HAVE_TIME is
not defined. In this case, do not attempt to seed the pseudo-random
number generator used to sometimes produce corrupt packets and other
erroneous data.

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.

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().

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.

Used to print "cipher:" when it was the cipher part of a program that
had both cipher and PSA. Now it doesn't really make sense. Align the
output to match the PSA version of this program.
