This commit updates $license variable in all APKBUILDs to comply with
short names specified by SPDX version 3.0 [1] where possible. It was
done using find-and-replace method on substrings inside $license
variables.

Only license names were updated, not "expressions" specifying relation
between the licenses (e.g. "X and Y", "X or Y", "X and (Y or Z)") or
exceptions (e.g. "X with exceptions").

Many licenses have a version or multiple variants, e.g. MPL-2.0,
BSD-2-Clause, BSD-3-Clause. However, $license in many aports do not
contain license version or variant. Since there's no way how to infer
this information just from abuild, it were left without the variant
suffix or version, i.e. non SPDX compliant.

GNU licenses (AGPL, GFDL, GPL, LGPL) are especially complicated. They
exist in two variants: -only (formerly e.g. GPL-2.0) and -or-later
(formerly e.g. GPL-2.0+). We did not systematically noted distinguish
between these variants, so GPL-2.0, GPL2, GPLv2 etc. may mean
GPL-2.0-only or GPL-2.0-or-later. Thus GNU licenses without "+" (e.g.
GPL2+) were left without the variant suffix, i.e. non SPDX compliant.

Note: This commit just fixes format of the license names, no
verification has been done if the specified license information is
actually correct!

This moves all packages from testing to unmaintained which have not been
updated for atleast 6 months. If you are affected by this commit please follow
this proceddure:

* make sure your packages build on all architectures
* move your pacakge(s) back to testing
* if you want to keep this package and can maintain it (or find somebody to
  maintain it for you) for a minimum of 6 months ask it to be moved to community

Package description:
The purpose of Dnsenum is to gather as much information as possible
about a domain. The program currently performs the following operations:

1) Get the host's addresse (A record).
2) Get the namservers (threaded).
3) Get the MX record (threaded).
4) Perform axfr queries on nameservers and get BIND versions(threaded).
5) Get extra names and subdomains via google scraping
   (google query = "allinurl: -www site:domain").
6) Brute force subdomains from file, can also perform recursion on
   subdomain that have NS records (all threaded).
7) Calculate C class domain network ranges and perform whois queries
   on them (threaded).
8) Perform reverse lookups on netranges ( C class or/and whois netranges).
9) Write to domain_ips.txt file ip-blocks.
