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.

ssl_client2.c used to check that we force a ciphersuite that worked;
that would have prevented testing so I removed it. The library should be
robust even when the application tries something that doesn't work.

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.

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

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

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.

If -f was used as an argument twice to the program, then it would leak
the file resource, due to overwriting it on the second pass

Non-regression for the fix in https://github.com/ARMmbed/mbedtls/pull/5126:
libmbedtls and libmbedx509 did not declare their dependencies on libmbedx509
and libmbedcrypto when built with make.
