the experimental buildd for powerpc was failing because it pulled in
automake1.11.  it failed with:

Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ \t=:+{}]+)}/ at /usr/bin/automake line 4159.
configure.ac:50: option `serial-tests' not recognized
autoreconf: automake failed with exit status: 1
dh_autoreconf: autoreconf -f -i returned exit code 1
debian/rules:6: recipe for target 'build-arch' failed
make: *** [build-arch] Error 2
dpkg-buildpackage: error: debian/rules build-arch gave error exit status 2

https://buildd.debian.org/status/fetch.php?pkg=gnupg1&arch=powerpc&ver=1.4.20-6%2Bexp4&stamp=1470619435

this attempts to force it to do the right thing.

move to newer, simpler dh-style build process, with explicitly
installed artifacts via debian/*.install and other dh helper files.

This should make it easier to maintain in the future, and should
include build hardening and other improvements automagically as the
toolchain improves.

 * fix lintian-overrides
 * use Vcs- fields which match the new source package name

 * use https
 * add myself to debian/copyright as author of files in debian/
 * identify as "classic" (compare with "modern" gnupg2)
 * correct information about source files

/usr/share/info/gnupg1.info.gz has been shipped with gnupg 1.4
packages for a while.  the .info file is the only file that is being
shipped in the same location after the transition to gnupg1.

In 2016 or later, anyone who is still trying to convert from GnuPG
1.0.6 or later has more important projects ahead of them than using
this conversion utility.

If they need the utility, they can fetch it from source.
