doc: update urls in manual and include checklinkx script. * doc/automake.texi: update many urls; http -> https, search.cpan.org -> metacpan.org/pod/distribution, node names, etc. Remove sourceware.org/cgi-bin/gnatsweb.pl and miller.emu.id.au/pmiller/books/rmch/ as these are 404 and no good replacement is evident. s/perl/Perl/ a couple times in text for good measure. * contrib/checklinkx: new script, a small modification of W3C checklink <https://validator.w3.org/checklink/docs/checklink.html> (W3C license, which is free software), starting from version 4.81 installed from CPAN: https://metacpan.org/pod/distribution/W3C-LinkChecker/bin/checklink.pod * doc/local.mk (checklinkx): new target to invoke it, with variables. * Makefile.am (EXTRA_DIST): distribute it. * NEWS: mention all this.
