Remove pkgviews: don't set PKG_INSTALLATION_TYPES in Makefiles.

Log message:
Bump for perl-5.20.0.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.

Log message:
Bump all packages for perl-5.18, that
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package

Like last time, where this caused no complaints.

Log message:
Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.

Log message:
Bump all packages that use perl, or depend on a p5-* package, or
are called p5-*.

I hope that's all of them.

Log message:
Import Net::Frame into net/p5-Net-Frame. This package is provided in
PR pkg/45720.

Net::Frame is a fork of Net::Packet. The goal here was to greatly simplify
the use of the frame crafting framework. Net::Packet does many things
undercover, and it was difficult to document all the thingies.

Also, Net::Packet may suffer from unease of use, because frames were assembled
using layers stored in L2, L3, L4 and L7 attributes. Net::Frame removes all
this, and is splitted in different modules, for those who only want to use part
of the framework, and not whole framework.

Finally, anyone can create a layer, and put it on his CPAN space, because of
the modularity Net::Frame offers. For an example, see Net::Frame::Layer::ICMPv4
on my CPAN space.

Net::Frame does ship with basic layers, to start playing.
