see #2788
Debian only has 1.11 as an old version, so it's unlikely we need
something older (I guess Debian doesn't reconf as much as we do though...)
The install script tasks are all handled by a hook now.
In some cases this will introduce cycles which could likely be cleaned
up by only depending on some unix tools instead of the whole autotools.
Rebuilding doesn't make much sense at this point since it just adds a subset
of base-devel which is still installed by default.
This also removes the pgp checks for everything except 1.16 because
they don't contain the full key ID and can't be auto fetched by gnupg.
Since we have the checksums and they wont be updated in the future anyway
this shouldn't be a problem.
The tests didn't work anyway, so removing Python 2 doesn't change much.
* upgrade some broken packages
* correct some broken urls/checksums
* use secure urls where possible
* use stable url for ncurses
* some whitespace fixes
Remaining md5sums either didn't download or
didn't pass checksum tests.
