go recently received a security upgrade to 1.12.8 (f4894bf9) this
upgrade fixes various CVEs in go standard libraries, for instance in
HTTP/2 functionality. Since go is statically linked packages using this
functionality need to be rebuild.

This makes it possible to provide armv7 as additional architecture in
Alpine, next to armhf. See the discussion in this ML thread:
<https://lists.alpinelinux.org/alpine-devel/6271.html>

It's done by adding armv7 next to armhf in the arch line and also
!armv7 where the arch line said !armhf. The following script was used:

backport a patch that fixes tests in 32 bits archs

Also remove a patch that is already applied upstream.

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!

Seems all tests are passing on s390x with syncthing 0.14.41

Most of these updates is based on data from https://repology.org/,
detection based on permanent redirect from http:// to https://.

$source urls are updated when they contain $url as substring.

* do not fetch whole sha256-simd tarball but just patch it (even if s390x is disabled).
* enable strip again: https://dominik.honnef.co/posts/2016/10/go-and-strip.
* update initd to support multiple instances and add logging.
* fix build by removing symlink project in builddir and just copy it.

Currently ppc64le does not have go, thus, disabling the build of
the packages that depends on golang.

This patch should be reverted once we have go enabled on ppc64le.
