When establishing an outbound connection for TLS distribution, let's
hold on to the failure reasons and use them as exit reasons. These
exit reasons are normally invisible, but they can be seen in the logs
after calling net_kernel:verbose(1).
While there are trace messages in the code already, those require
recompiling the module with a special flag, which is more cumbersome
than changing the net_kernel verbosity level at run time.

If ssl:ssl_accept/2 returns an error related to options, it's most
likely something we want to log. In particular, if the specified
certificate file doesn't exist, this is where the error ends up, so we
shouldn't just throw the error away.

alert records needs to be thrown from
ssl_handshake:premaster_secret/[2/3] so that operations will end up in
the catch clause of the invokation of certify_client_key_exchange/3 in
ssl_connection.erl, and hence terminate gracefully and not continue to try
and calculate the master secret with invalid inputs and crash.

For comparison with file time stamps os:timestamp makes more sense
and is present in 17 as well as 18.

The PEM cache is now validated by a background process, instead of
always keeping it if it is small enough and clearing it otherwhiss.
That strategy required that small caches where cleared by API function
if a file changes on disk.
However document the clearing API function as it can still be usefull.

A selfsigned trusted anchor should not be in the certifcate chain passed to
the certificate path validation.

Check that the certificate chain ends with a trusted ROOT CA e.i. a
self-signed certificate, but provide an option partial_chain to
enable the application to define an intermediat CA as trusted.
TLS RFC says:
"unknown_ca
A valid certificate chain or partial chain was received, but the
certificate was not accepted because the CA certificate could not
be located or couldn't be matched with a known, trusted CA. This
message is always fatal."
and also states:
"certificate_list
This is a sequence (chain) of certificates. The sender's
certificate MUST come first in the list. Each following
certificate MUST directly certify the one preceding it. Because
certificate validation requires that root keys be distributed
independently, the self-signed certificate that specifies the root
certificate authority MAY be omitted from the chain, under the
assumption that the remote end must already possess it in order to
validate it in any case."
X509 RFC says:
"The selection of a trust anchor is a matter of policy: it could be
the top CA in a hierarchical PKI, the CA that issued the verifier's
own certificate(s), or any other CA in a network PKI. The path
validation procedure is the same regardless of the choice of trust
anchor. In addition, different applications may rely on different
trust anchors, or may accept paths that begin with any of a set of
trust anchors."

When dealing with older certificates that does not indicate its signer
with a certificate extension, we must search the database for the issure.
Finding the issuer is not enough, we need to verify the signature
with the key in the found issuer cert.

Use generated certs instead of hard coded

FROM TLS 1.2 RFC:
The interaction of the certificate_types and
supported_signature_algorithms fields is somewhat complicated.
certificate_types has been present in TLS since SSLv3, but was
somewhat underspecified. Much of its functionality is superseded by
supported_signature_algorithms. The following rules apply:
- Any certificates provided by the client MUST be signed using a
hash/signature algorithm pair found in
supported_signature_algorithms.
- The end-entity certificate provided by the client MUST contain a
key that is compatible with certificate_types. If the key is a
signature key, it MUST be usable with some hash/signature
algorithm pair in supported_signature_algorithms.
- For historical reasons, the names of some client certificate types
include the algorithm used to sign the certificate. For example,
in earlier versions of TLS, rsa_fixed_dh meant a certificate
signed with RSA and containing a static DH key. In TLS 1.2, this
functionality has been obsoleted by the
supported_signature_algorithms, and the certificate type no longer
restricts the algorithm used to sign the certificate. For
example, if the server sends dss_fixed_dh certificate type and
{{sha1, dsa}, {sha1, rsa}} signature types, the client MAY reply
with a certificate containing a static DH key, signed with RSA-
SHA1.
