Fix file lists on packages.d.o. (Closes: #977006, #977743, #980888, #923974)

See merge request !20

This commit changes the logic of existing code. The author was not sure if the
existing code performed as it should. The '-l' file test on the Contents.gz data
files will not capture symbolic links for suite aliases on the suite level.

Looks at the suite level instead.

Concatenate results from Contents-${arch}.gz and Contents-all.gz when the latter is present. (Closes: #977006, #977743, #980888)

Since commit 81824d23 in daklib, the archive provides separate Contents files
with packages from Arch:all for some suites. [1] (All suites post-buster appear to
be affected.) Those file lists were not scanned for the web pages powering
packages.d.o, and the file lists were unavailable online.

This commit attempts to resolve the issue by parsing the file for Arch:all
immediately afterwards, if it is present. The results are effectively
concatenated.

A better long-term solution might be to produce separate transfer files for
Arch:all, but that may not work until buster is dropped from the archive.

rc-buggy is just another name for the experimental distribution, as seen
in dak's config/debian/dak.conf under SuiteMappings:

  "map rc-buggy experimental";

So there's no reason to rewrite experimental as rc-buggy. Do the reverse
transformation instead. This solves various lookup errors where index
files wouldn't be found because their filenames would refer to rc-buggy.

Following Boyuan Yang's example,
see commit eee307e1

This solves the problem of
https://lists.debian.org/debian-www/2018/05/msg00010.html .

This should solve Debian Bug 703237.

Use https where available, and update some Debian Policy links to the
new layout.

Using cmdline:

(polangs="bg de fi fr hu ja nl pl ru sk sv tr uk zh-cn zh-tw" ;
topdir=$(realpath .); podir=$topdir/po; libdir=$topdir/lib; .
./cron.d/500update_po)

* sources.debian.net -> sources.debian.org migration
* replace packages.qa.debian.org with tracker.debian.org
  (Closes: #756397)
* update URL for debian patch tracker (Closes: #831435)

Do not update debtags.po when files/debtags/vocabulary file does not
exist.

Also fixed some indent problems.

Debian-policy is now put inside one page instead of separate pages.
Links to its contents are updated accordingly.

Make changes to reflect the new debian order:
 strech is now stable
 jessie is now oldstable
 wheezy is now oldoldstable

The size of uncompressed data can be determined by using gzip -l's
output, so let's do that to improve reporting.

Since we're using a temporary file now, we know exactly which amount of
data is being worked on, so let's report accurate numbers.
