fetchmail: Update to 6.1.25

upstream changes:
-----------------
fetchmail-6.4.25 (released 2021-12-10, 31653 LoC):

# BREAKING CHANGES:
* Since distributions continue patching for LibreSSL use, which cannot be
  linked legally, block out LibreSSL in configure.ac and socket.c, and
  refer to COPYING, unless on OpenBSD (which ships it in the base system).
  OpenSSL and wolfSSL 5 can be used.  SSL-related documentation was updated, do
  re-read COPYING, INSTALL, README, README.packaging, README.SSL.
* Bump OpenSSL version requirement to 1.0.2f in order to safely remove
  the obsolete OpenSSL flag SSL_OP_SINGLE_DH_USE. This blocks out 1.0.2e and
  older 1.0.2 versions. 1.0.2f was a security fix release, and 1.0.2u is
  publicly available from https://www.openssl.org/source/old/1.0.2/
* Some of the configure.ac fiddling MIGHT have broken cross-compilation
  again. The maintainer does not test cross-compiling fetchmail; if you
  have difficulties, try setting PKG_CONFIG_LIBDIR to the pkg-config path
  containing your target/host libraries, or see if --with-ssl-prefix or
  --with-wolfssl-prefix, or overriding LDFLAGS/LIBS/CPPFLAGS, can help.
  Feedback solicited on compliant systems that are before end-of-life.

# BUG FIXES:
* 6.4.24's workaround for OpenSSL 1.0.2's X509_V_FLAG_TRUSTED_FIRST flag
  contained a typo and would not kick in properly.
* Library and/or rpath setting from configure.ac was fixed.

# ADDITIONS:
* Added an example systemd unit file and instructions to contrib/systemd/
  which runs fetchmail as a daemon with 5-minute poll intervals.
  Courteously contributed by Barak A. Pearlmutter, Debian Bug#981464.
* fetchmail can now be used with wolfSSL 5's OpenSSL compatibility layer,
  see INSTALL and README.SSL. This is considered experimental.
  Feedback solicited.

# CHANGES:
* The getstats.py dist-tool now counts lines of .ac and .am files.
* ./configure --with-ssl now supports pkg-config module names, too. See INSTALL.

fetchmail-6.4.24 (released 2021-11-20, 30218 LoC):

# OPENSSL AND LICENSING NOTE:
> see fetchmail-6.4.22 below, and the file COPYING.

  Note that distribution of packages linked with LibreSSL is not feasible
  due to a missing GPLv2 clause 2(b) exception.

# COMPATIBILITY:
* Bison 3.8 dropped yytoknum altogether, breaking compilation due to a
  warning workaround. Remove the cast of yytoknum to void.  This may cause
  a compiler warning to reappear with older Bison versions.
* OpenSSL 1.0.2: Workaround for systems that keep the expired DST Root CA X3
  certificate in its trust store because OpenSSL by default prefers the
  untrusted certificate and fails.  Fetchmail now sets the
  X509_V_FLAG_TRUSTED_FIRST flag (on OpenSSL 1.0.2 only).
  This is workaround #2 from the OpenSSL Blog.  For details, see both:
  https://www.openssl.org/blog/blog/2021/09/13/LetsEncryptRootCertExpire/
  https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/

  NOTE: OpenSSL 1.0.2 is end of life, it is assumed that the OpenSSL library
  is kept up to date by a distributor or via OpenSSL support contract.
  Where this is not the case, please upgrade to a supported OpenSSL version.

# DOCUMENTATION:
* The manual page was revised after re-checking with mandoc -Tlint, aspell,
  igor. Some more revisions were made for clarity.

fetchmail-6.4.23 (released 2021-10-31, 30206 LoC):

# USABILITY:
* For common ssh-based IMAP PREAUTH setups (i. e. those that use a plugin
  - no matter its contents - and that set auth ssh), change the STARTTLS
  error message to suggest sslproto '' instead.
  This is a commonly reported issue after the CVE-2021-39272 fix in 6.4.22.
  Fixes Redhat Bugzilla 2008160. Fixes GitLab #39.

fetchmail-6.4.22 (released 2021-09-13, 30201 LoC):

# OPENSSL AND LICENSING NOTE:
* fetchmail 6.4.22 is compatible with OpenSSL 1.1.1 and 3.0.0.
  OpenSSL's licensing changed between these releases from dual OpenSSL/SSLeay
  license to Apache License v2.0, which is considered incompatible with GPL v2
  by the FSF.  For implications and details, see the file COPYING.

# SECURITY FIXES:
* CVE-2021-39272: fetchmail-SA-2021-02: On IMAP connections, without --ssl and
  with nonempty --sslproto, meaning that fetchmail is to enforce TLS, and when
  the server or an attacker sends a PREAUTH greeting, fetchmail used to continue
  an unencrypted connection.  Now, log the error and abort the connection.
  --Recommendation for servers that support SSL/TLS-wrapped or "implicit" mode on
  a dedicated port (default 993): use --ssl, or the ssl user option in an rcfile.
  --Reported by: Andrew C. Aitchison, based on the USENIX Security 21 paper "Why
  TLS is better without STARTTLS - A Security Analysis of STARTTLS in the Email
  Context" by Damian Poddebniak, Fabian Ising, Hanno Böck, and Sebastian
  Schinzel.  The paper did not mention fetchmail.

* On IMAP and POP3 connections, --auth ssh no longer prevents STARTTLS
  negotiation.
* On IMAP connections, fetchmail does not permit overriding a server-side
  LOGINDISABLED with --auth password any more.
* On POP3 connections, the possibility for RPA authentication (by probing with
  an AUTH command without arguments) no longer prevents STARTTLS negotiation.
* For POP3 connections, only attempt RPA if the authentication type is "any".

# BUG FIXES:
* On IMAP connections, when AUTHENTICATE EXTERNAL fails and we have received the
  tagged (= final) response, do not send "*".
* On IMAP connections, AUTHENTICATE EXTERNAL without username will properly send
  a "=" for protocol compliance.
* On IMAP connections, AUTHENTICATE EXTERNAL will now check if the server
  advertised SASL-IR (RFC-4959) support and otherwise refuse (fetchmail <= 6.4
  has not supported and does not support the separate challenge/response with
  command continuation)
* On IMAP connections, when --auth external is requested but not advertised by
  the server, log a proper error message.
* Fetchmail no longer crashes when attempting a connection with --plugin "" or
  --plugout "".
* Fetchmail no longer leaks memory when processing the arguments of --plugin or
  --plugout on connections.
* On POP3 connections, the CAPAbilities parser is now caseblind.
* Fix segfault on configurations with "defaults ... no envelope". Reported by
  Bjørn Mork. Fixes Debian Bug#992400.  This is a regression in fetchmail 6.4.3
  and happened when plugging memory leaks, which did not account for that the
  envelope parameter is special when set as "no envelope". The segfault happens
  in a constant strlen(-1), triggered by trusted local input => no vulnerability.
* Fix program abort (SIGABRT) with "internal error" when invalid sslproto is
  given with OpenSSL 1.1.0 API compatible SSL implementations.

# CHANGES:
* IMAP: When fetchmail is in not-authenticated state and the server volunteers
  CAPABILITY information, use it and do not re-probe. (After STARTTLS, fetchmail
  must and will re-probe explicitly.)
* For typical POP3/IMAP ports 110, 143, 993, 995, if port and --ssl option
  do not match, emit a warning and continue. Closes Gitlab #31.
  (cherry-picked from 6.5 beta branch "legacy_6x")
* fetchmail.man and README.SSL were updated in line with RFC-8314/8996/8997
  recommendations to prefer Implicit TLS (--ssl/ssl) and TLS v1.2 or newer,
  placing --sslproto tls1.2+ more prominently.
  The defaults shall not change between 6.4.X releases for compatibility.
