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.

In order to be able to test extensions with SSL connections, allow
configure_test_server_for_ssl to create any extensions passed as
an array. Each extension is created in all the test databases.

The five modules in our TAP test framework all had names in the top
level namespace. This is unwise because, even though we're not
exporting them to CPAN, the names can leak, for example if they are
exported by the RPM build process. We therefore move the modules to the
PostgreSQL::Test namespace. In the process PostgresNode is renamed to
Cluster, and TestLib is renamed to Utils. PostgresVersion becomes simply
PostgreSQL::Version, to avoid possible confusion about what it's the
version of.

Also "make reformat-dat-files".
The only change worthy of note is that pgindent messed up the formatting
of launcher.c's struct LogicalRepWorkerId, which led me to notice that
that struct wasn't used at all anymore, so I just took it out.

test_connect_ok() and test_connect_fails() have always been part of the
SSL tests, and check if a connection to the backend should work or not,
and there are sanity checks done on specific error patterns dropped by
libpq if the connection fails.
This was fundamentally wrong on two aspects. First, SSLServer.pm works
mostly on setting up and changing the SSL configuration of a
PostgresNode, and has really nothing to do with the client. Second,
the situation became worse in light of b34ca595, where the SSL tests
would finish by using a psql command that may not come from the same
installation as the node set up.
This commit moves those client routines into PostgresNode, making easier
the refactoring of SSLServer to become more SSL-implementation aware.
This can also be reused by the ldap, kerberos and authentication test
suites for connection checks, and a follow-up patch should extend those
interfaces to match with backend log patterns.

Currently we only recognize the Common Name (CN) of a certificate's
subject to be matched against the user name. Thus certificates with
subjects '/OU=eng/CN=fred' and '/OU=sales/CN=fred' will have the same
connection rights. This patch provides an option to match the whole
Distinguished Name (DN) instead of just the CN. On any hba line using
client certificate identity, there is an option 'clientname' which can
have values of 'DN' or 'CN'. The default is 'CN', the current procedure.
The DN is matched against the RFC2253 formatted DN, which looks like
'CN=fred,OU=eng'.
This facility of probably best used in conjunction with an ident map.

Add another method to specify CRLs, hashed directory method, for both
server and client side. This offers a means for server or libpq to
load only CRLs that are required to verify a certificate. The CRL
directory is specifed by separate GUC variables or connection options
ssl_crl_dir and sslcrldir, alongside the existing ssl_crl_file and
sslcrl, so both methods can be used at the same time.

Reuse cautionary language from src/test/ssl/README in
src/test/kerberos/README. SLRUs have had access to six-character
segments names since commit 73c986adde5d73a5e2555da9b5c8facedb146dcd,
and recovery stopped calling HeapTupleHeaderAdvanceLatestRemovedXid() in
commit 558a9165e081d1936573e5a7d576f5febd7fb55a. The other corrections
are more self-evident.

Instead of hard-wiring the netmask as /32, allow it to be specified
where we specify the server address. This will ease changing the
test to use IPv6, when/if somebody wants to do that.
Also remove the hard-wired pg_hba.conf entries for IPv6 (::1/128).
These have never had any usefulness, because the client side
of the tests has always explicitly connected to $SERVERHOSTADDR
which has always been set to IPv4 (127.0.0.1). All they accomplish
is to break the test on non-IPv6-supporting hosts, and besides
that they violate the express intent of the code to minimize the
server's range of allowed connections.
This could be back-patched, perhaps, but for now I don't see
a need to.

Support is out of scope from all the major vendors for these versions
(for example RHEL5 uses a version based on 0.9.8, and RHEL6 uses 1.0.1),
and it created some extra maintenance work. Upstream has stopped
support of 0.9.8 in December 2015 and of 1.0.0 in February 2016.
Since b1abfec, note that the default SSL protocol version set with
ssl_min_protocol_version is TLSv1.2, whose support was added in OpenSSL
1.0.1, so there is no point to enforce ssl_min_protocol_version to TLSv1
in the SSL tests.

Change default of ssl_min_protocol_version to TLSv1.2 (from TLSv1,
which means 1.0). Older versions are still supported, just not by
default.
TLS 1.0 is widely deprecated, and TLS 1.1 only slightly less so. All
OpenSSL versions that support TLS 1.1 also support TLS 1.2, so there
would be very little reason to, say, set the default to TLS 1.1
instead on grounds of better compatibility.
The test suite overrides this new setting, so it can still run with
older OpenSSL versions.

This allows a login to require both that the cn of the certificate
matches (like authentication type cert) *and* that another
authentication method (such as password or kerberos) succeeds as well.
The old value of clientcert=1 maps to the new clientcert=verify-ca,
clientcert=0 maps to the new clientcert=no-verify, and the new option
erify-full will add the validation of the CN.

The modules RewindTest.pm and ServerSetup.pm are really only useful for
TAP tests, so they really belong in the TAP test directories. In
addition, ServerSetup.pm is renamed to SSLServer.pm.
The test scripts have their own directories added to the search path so
that the relocated modules will be found, regardless of where the tests
are run from, even on modern perl where "." is no longer in the
searchpath.
