inv_mod() already returns a specific error code if the value is not
invertible, so no need to check in advance that it is. Also, this is a
preparation for blinding the call to inv_mod(), which is made easier by
avoiding the redundancy (otherwise the call to gcd() would need to be blinded
too).

In the next commit, we'll need to draw a second random value, in order to
blind modular inversion. Having a function for that will avoid repetition.

CTR-DRBG and HMAC-DRBG may used the seed differently depending on its length.

Pass the "certificate policies" extension to the callback supplied to
mbedtls_x509_crt_parse_der_with_ext_cb() if it contains unsupported
policies. This allows the callback to fully replicate the behaviour
of the deprecated MBEDTLS_X509_ALLOW_UNSUPPORTED_CRITICAL_EXTENSION
configuration.

These fields might be shifted accordingly in `ssl_parse_record_header()`
when receiving a connection with CID, so they require a manual update
after calling the generic `mbedtls_ssl_reset_in_out_pointers()`.
This commit also adds a regression test which is run by all.sh.

Another coverity bug - #350039
When this test discovers a key of the wrong type, it still throws it
through the export function in order to check that it too will detect
this as a not permitted action. For the buffer and buffer length
arguments it passes in a local pointer (which will most likely be NULL),
and the sizeof that pointer, as it knows that they will never be used.
Coverity rightly (imho) flagged this as suspicious - if we are going to
pass in incorrect parameters, at least make them obviously incorrect, and
ones that will not potentially cause errors if the code later changes.
There is, for example safety checks for zero length buffer, but less
protection for an insufficiently sized one.

1. When `ssl_server2` export key functionality fails,
don't exit the server, but reset it, to have the
server recover for next connection.
2. Add text filters for `export keys functionality` test in ssl-opt.sh
to check for additional output, to verify if the export suceeded.
This was discovered in the `ssl-opt.sh` script, where the server exited,
before the test tried to kill the server priocess, resulting in a
`kill: No such process` message.

The purpose of random.c file is to contain the helper
functions to generate random numbers that have been
in helpers.function so far.
The purpose of random.h is to contain the interface
exposed by random.c thus helper function prototypes.
