[tin-dev] [tin 2.6.2] snapshots with NNTPS and pcre2

[Urs Janßen]

After ~21 years Enrik spent again some time on tin and switched the
networking code from tdio to own buffer implementation (which was a
blocker for e.g. NNTPS support), added NNTPS support based on
libressl/gnuttls/OpenSSL and added pcre2 support. 

Kudos to Enrik!

For pcre2 use "configure --with-pcre2-config[=PATH]" instead of
"--with-pcre[=PATH]". Old pcre code can still be enabled instead and
the very outdated copy of the code is still included for platforms where
no newer lib is available...

For NNTPS support use "configure --with-nntps[=[libtls|openssl|gnutls]]".
(requires LibreSSL TLS_API >= 20200120 or OpenSSL >= 1.1.1 or GnuTLS >= 3.7.0)

The configure stuff looks a bit cumbersome, feel free to improve it.

As the NNTPS (currently) has no debug-level or info-screen a new file
${TIN_HOMEDIR:\-"$HOME"}/.tin/tinmsglog will be rewritten on every
invocation which holds a copy of all wait_/error_messages and might be
useful for debugging. This is not yet documented and the location of the
file and the name is likely to be changed.

Use the -T cmd.line switch to use NNTPS instead of NNTP. If the certificate
of the server can not be verified tin will quit. This can be bypassed with
-k (like in curl). Of course that should be avoided.

The code needs some testing esp. on non x86-64-linux systems!
