This adds the X509 attributes notBefore and notAfter to sslinfo
as well as pg_stat_ssl to allow verifying and identifying the
validity period of the current client certificate. OpenSSL has
APIs for extracting notAfter and notBefore, but they are only
supported in recent versions so we have to calculate the dates
by hand in order to make this work for the older versions of
OpenSSL that we still support.

There are a lot of Perl scripts in the tree, mostly code generation
and TAP tests. Occasionally, these scripts produce warnings. These
are probably always mistakes on the developer side (true positives).
Typical examples are warnings from genbki.pl or related when you make
a mess in the catalog files during development, or warnings from tests
when they massage a config file that looks different on different
hosts, or mistakes during merges (e.g., duplicate subroutine
definitions), or just mistakes that weren't noticed because there is a
lot of output in a verbose build.
This changes all warnings into fatal errors, by replacing
use warnings;
by
use warnings FATAL => 'all';
in all Perl files.

Run pgindent, pgperltidy, and reformat-dat-files.
This set of diffs is a bit larger than typical. We've updated to
pg_bsd_indent 2.1.2, which properly indents variable declarations that
have multi-line initialization expressions (the continuation lines are
now indented one tab stop). We've also updated to perltidy version
20230309 and changed some of its settings, which reduces its desire to
add whitespace to lines to make assignments etc. line up. Going
forward, that should make for fewer random-seeming changes to existing
code.

The sslcertmode option controls whether the server is allowed and/or
required to request a certificate from the client. There are three
modes:
- "allow" is the default and follows the current behavior, where a
configured client certificate is sent if the server requests one
(via one of its default locations or sslcert). With the current
implementation, will happen whenever TLS is negotiated.
- "disable" causes the client to refuse to send a client certificate
even if sslcert is configured or if a client certificate is available in
one of its default locations.
- "require" causes the client to fail if a client certificate is never
sent and the server opens a connection anyway. This doesn't add any
additional security, since there is no guarantee that the server is
validating the certificate correctly, but it may helpful to troubleshoot
more complicated TLS setups.
sslcertmode=require requires SSL_CTX_set_cert_cb(), available since
OpenSSL 1.0.2. Note that LibreSSL does not include it.
Using a connection parameter different than require_auth has come up as
the simplest design because certificate authentication does not rely
directly on any of the AUTH_REQ_* codes, and one may want to require a
certificate to be sent in combination of a given authentication method,
like SCRAM-SHA-256.
TAP tests are added in src/test/ssl/, some of them relying on sslinfo to
check if a certificate has been set. These are compatible across all
the versions of OpenSSL supported on HEAD (currently down to 1.0.1).

To avoid duplicating the PG_TEST_EXTRA logic in Makefiles into the upcoming
meson based build definition, move the checks into the the tests
themselves. That also has the advantage of making skipped tests visible.

The SSL TAP tests were tightly coupled to the OpenSSL implementation,
making it hard to add support for additional SSL/TLS backends. This
refactoring makes the test avoid depending on specific implementations
The SSLServer Perl module is renamed SSL::Server, which in turn use
SSL::Backend::X where X is the backend pointed to by with_ssl. Each
backend will implement its own module responsible for setting up keys,
certs and to resolve sslkey values to their implementation specific
value (file paths or vault nicknames etc). Further, switch_server_cert
now takes a set of named parameters rather than a fixed set which used
defaults. The modules also come with POD documentation.
There are a few testcases which still use OpenSSL specifics, but it's
not entirely clear how to abstract those until we have another library
implemented.
Original patch by me, with lots of rework by Andrew Dunstan to turn it
into better Perl.

This issue is environment-sensitive, where the SSL tests could fail in
various way by feeding on defaults provided by sslcert, sslkey,
sslrootkey, sslrootcert, sslcrl and sslcrldir coming from a local setup,
as of ~/.postgresql/ by default. Horiguchi-san has reported two
failures, but more advanced testing from me (aka inclusion of garbage
SSL configuration in ~/.postgresql/ for all the configuration
parameters) has showed dozens of failures that can be triggered in the
whole test suite.
History has showed that we are not good when it comes to address such
issues, fixing them locally like in dd87799, and such problems keep
appearing. This commit strengthens the entire test suite to put an end
to this set of problems by embedding invalid default values in all the
connection strings used in the tests. The invalid values are prefixed
in each connection string, relying on the follow-up values passed in the
connection string to enforce any invalid value previously set. Note
that two tests related to CRLs are required to fail with certain pre-set
configurations, but we can rely on enforcing an empty value instead
after the invalid set of values.

Rather than doing manual book keeping to plan the number of tests to run
in each TAP suite, conclude each run with done_testing() summing up the
the number of tests that ran. This removes the need for maintaning and
updating the plan count at the expense of an accurate count of remaining
during the test suite runtime.
This patch has been discussed a number of times, often in the context of
other patches which updates tests, so a larger number of discussions can
be found in the archives.

The connection strings in the SSL client tests were using the host
set up from Cluster.pm which is a temporary pathname. When SNI is
enabled we pass the host to OpenSSL in order to set the server name
indication ClientHello extension via SSL_set_tlsext_host_name.
OpenSSL doesn't validate the hostname apart from checking the max
length, but LibreSSL checks for RFC 5890 conformance which results
in errors during testing as the pathname from Cluster.pm is not a
valid hostname.
Fix by setting the host explicitly to localhost, as that's closer
to the intent of the test.
Backpatch through 14 where SNI support came in.

The temporary path generated in commit c113d8ad5 cannot be passed as-is in
the connection string on Windows since the path delimiting backslashes will
be treated as escape characters. Fix by converting backslash to slash as in

Commit c113d8ad50 moved the copying of certificates into a temporary path
for the duration of the tests, instead of using the source tree. This broke
the tests on msys as the absolute path wasn't adapted for the msys platform.
Ensure to convert the path with perl2host before copying and passing in the
connection string.
While there also make certificate copying error handling uniform across all
the test suites.

This adds rudimentary coverage of the sslinfo extension into the SSL
test harness. The output is validated by comparing with pg_stat_ssl
to provide some level of test stability should the underlying certs
be slightly altered. A new cert is added to provide an extension to
test against.
