Log message:
Bump the PKGREVISION for all packages which depend directly on perl,
to trigger/signal a rebuild for the transition 5.10.1 -> 5.12.1.

The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=..."), minus the packages updated after
the perl package update.

sno@ was right after all, obache@ kindly asked and he@ led the
way. Thanks!

Log message:
Importing package devel/p5-Test-UseAllModules for p5 module
Test::UseAllModules v0.12 from PR pkg/42023 with minor modifications.

Sick of writing 00_load.t (or something like that) that do use_ok() for every
written module? Even sicker of updating 00_load.t every time adding another file
to the distro? This module reads MANIFEST to find modules to be tested and does
use_ok() for each of them. Now all to do is keeping MANIFEST up to date.
