Adapted from the section in Mbed Crypto, with the addition of specific
compiler versions. Only mention Python 3; Python 2 may still work but
it is no longer supported upstream so we will not maintain
compatibility anymore.
The .pl version is now a compat wrapper around the .py script. Better call the
.py script directly.

A number of clean-up improvements following review.
* removal of redundant `` quotes
* removal of non-portable echo "\n", in favour of additional echo commands
* change to use of uname to detemine if the platform is Linux or not
* revised formatting of output
* change to dpkg-query from dpkg to find installed libasan variants

For this test it is good to have a handshake messages length as big as
possible, so for the server the certificate verification mode is
changed from default NONE to REQUIRED. It requires the client to send
certificate date to the server during handshake

This commit adds additional information to the output_env.sh script of:
* Linux distribution version (if available)
* GDB version (if available)
It also makes some information clearer:
* the type of OpenSSL/GNUTLS version (legacy/default/next)
* and whether certain versions are not installed, or not configured
And it simplifies the error messages for absent tools.

Create and provide a structure with default options so that the caller won't have
to pass all of the parameters each time the handshake is called. In the future
this can be improved so that the options are passed as a string, just like in
ssl-opt.sh.

The ssl-opt.sh test cases using session resumption tend to fail occasionally
on the CI due to a race condition in how ssl_server2 and ssl_client2 handle
the reconnection cycle.
The server does the following in order:
- S1 send application data
- S2 send a close_notify alert
- S3 close the client socket
- S4 wait for a "new connection" (actually a new datagram)
- S5 start a handshake
The client does the following in order:
- C1 wait for and read application data from the server
- C2 send a close_notify alert
- C3 close the server socket
- C4 reset session data and re-open a server socket
- C5 start a handshake
If the client has been able to send the close_notify (C2) and if has been
delivered to the server before if closes the client socket (S3), when the
server reaches S4, the datagram that we start the new connection will be the
ClientHello and everything will be fine.
However if S3 wins the race and happens before the close_notify is delivered,
in S4 the close_notify is what will be seen as the first datagram in a new
connection, and then in S5 this will rightfully be rejected as not being a
valid ClientHello and the server will close the connection (and go wait for
another one). The client will then fail to read from the socket and exit
non-zero and the ssl-opt.sh harness will correctly report this as a failure.
In order to avoid this race condition in test using ssl_client2 and
ssl_server2, this commits introduces a new command-line option
skip_close_notify to ssl_client2 and uses it in all ssl-opt.sh tests that use
session resumption with DTLS and ssl_server2.
This works because ssl_server2 knows how many messages it expects in each
direction and in what order, and closes the connection after that rather than
relying on close_notify (which is also why there was a race in the first
place).
Tests that use another server (in practice there are two of them, using
OpenSSL as a server) wouldn't work with skip_close_notify, as the server won't
close the connection until the client sends a close_notify, but for the same
reason they don't need it (there is no race between receiving close_notify and
closing as the former is the cause of the later).
An alternative approach would be to make ssl_server2 keep the connection open
until it receives a close_notify. Unfortunately it creates problems for tests
where we simulate a lossy network, as the close_notify could be lost (and the
client can't retransmit it). We could modify udp_proxy with an option to never
drop alert messages, but when TLS 1.3 comes that would no longer work as the
type of messages will be encrypted.

On a valid RSA public key, mbedtls_rsa_export should succeed if you
ask for the public fields, but fail if you ask for private fields. The
code was expecting to succeed when asking for private fields, so
failed on every valid RSA public key.
