Log message:
*: Remove many GCC_REQD for particularly old GCCs

In many cases the reasoning is poorly documented, or the reasoning
for setting GCC_REQD is to work around a compiler bug. Practically
a c99 compiler is now required for bootstrap (in at least several
dependencies) so we can entirely rule out GCC versions before 3.0.

Log message:
archivers: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and SHA512
hashes.

Log message:
all: migrate some SourceForge homepage URLs back from https to http

https://mail-index.netbsd.org/pkgsrc-changes/2020/01/18/msg205146.html

In the above commit, the homepage URLs were migrated from http to https,
assuming that SourceForge would use the same host names for both http and
https connections. This assumption was wrong. Their documentation at
https://sourceforge.net/p/forge/documentation/Custom%20VHOSTs/ states
that the https URLs use the domain sourceforge.io instead.

To make the homepages from the above commit reachable again, pkglint has
been extended to check for reachable homepages. This check is only
enabled when the --network command line option is given.

Each of the homepages that referred to https://$project.sourceforge.net
before was migrated to https://$project.sourceforge.io (27), and if that
was not reachable, to the fallback URL http://$project.sourceforge.net
(163).

Log message:
all: migrate several HOMEPAGEs to https

pkglint --only "https instead of http" -r -F

With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.

This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.

p7zip: Apply a patch for CVE-2017-17969 (out-of-bounds-write)

Bump PKGREVISION

Log message:
*: Move SUBST_STAGE from post-patch to pre-configure

Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.

Log message:
p7zip: Enforce C++03

Clang 7svn defaults to C++11 and this code is not building with it.
This switch fixes the build.
