All of the initial work was done by Simon. Jakub cleaned up the
formatting issues, resolved the padding of bignum to match specs
and be interoperable with OpenSSH (and few more minor details).
Closes: #194.

For some reason, the mingw64 builds were failing on these inputs quite reliably
as the passed value was interpretted as a value larger than UINT32_MAX.
This was not caught before because the value is casted from size_t to uint32_t
implicitly so the MSBs were not affecting the result.

On mingw we are frequently getting a failure like this:
[ ERROR ] --- 451 is not within the range 1-450
This means the 50ms sleep did not manage to elapse the 50ms in the timeout
structure. Extending the range to 460 will give use more wiggle room if the
clock is not as it should be.

The global openssl configuration file automatically loads a pkcs11
provider, but it does it before we set up the token, which makes
the pkcs11 tests failing.
The workaround is to not load the global configuration, which is
delaying the loading of the pkcs11 provider to the time of first
use.
Consequently, this will require separate integration end-to-end
test that will verify the libssh works correctly with the pkcs11
provider loaded early.

.. to satisfy restricted environment or fuzzers
We are encountering weird issues in the oss-fuzz that the file disappears during
coverage build so I assume some corpus sneaked in, that contains some commands
that end up being executed as part of the coverage run causing it randomly
failing.
The solution I propose is to build fuzzers without ability to call arbitrary
commands on the filesystem (such as `rm -rf /`) as this is not the point the
fuzzers should be testing.
This is controlled by the WITH_EXEC CMake option (enabled by default).

Legacy code in 'ssh_set_callbacks' will fallback to
'ssh_legacy_log_callback' (if the current log cb is
NULL) setting the user data to the current session.
However, if any other session is created afterwards,
it won't update the user data with the new session,
potentially leading to a use-after-free.
Fixes#238.
