Upstream changes:
2019-03-03  k  <andk@cpan.org>

        * release 2.25

        * two weeks after the TRIAL release cpantesters have produced 298
        pass and 2 fail reports on 108 different configurations; the two
        fails are outliers I don't understand

        * no functional change over 2.25-TRIAL; only a couple in the
        distroprefs directory which is not used per default

2019-02-16  k  <andk@cpan.org>

        * release 2.25-TRIAL

        * fix: Avoid a warning when prompting install_help intro (Nicolas
        R/atoomic)

        * testfix: load the tested module early, before juggling with @INC

        * testfix: replace an exec with system and exit (greetings to Windows)

        * two more distroprefs lines

2019-02-14  k  <andk@cpan.org>

        * release 2.24-TRIAL

        * fix: set internal error state on writemakefile=NO in a rare case
        without any output

        * test fix: avoid a so far unreflected dependency on perldoc

        * a few more distroprefs

2019-02-10  k  <andk@cpan.org>

        * release 2.23-TRIAL

        * fix: when option cleanup_after_install is active, prevent
        rerunning make install after a cleanup; allow it only with the
        help of force; also prevent that it is triggered too early

        * fix: address #121162: support distroprefs for install.env

        * fix: the option h on cpan script now really ignores all other
        options and arguments

        * fix: Local::Null::Logger on cpan script did not honour
        CPANSCRIPT_LOGLEVEL

        * address #122520: exit 1 on unknown options on cpan script

        * address #94941: refuse to generate reports with CPAN::Reporter
        lower than 1.2011

        * fix: distropref method "goto" now inherits CALLED_FOR and other
        attributes from caller

        * fix: correct a buggy version comparison when testing version of
        Net::Ping

        * portability fix: ensure that Compress::Zlib supports gzopen()

        * internal fix: never overwrite internal attribute CALLED_FOR (no
        known user-relevant implications)

        * tiny test fixed uncovered by cpantesters, various tiny typo
        corrections

        * a couple of new and updated distroprefs files
