Up to now, there was a central list of variable name patterns that
defined whether a variable was printed as a sorted list, as a list or as
a single value.
Now each variable group decides on its own which of the variables are
printed in which way, using the usual glob patterns. This is more
flexible since different files sometimes differ in their naming
conventions.
Two variable groups are added: license (for everything related to
LICENSE) and go (for lang/go).
The return values of the postinstall and postremove meta-tasks are
ignored unless the user-settable variable ${PKG_FATAL_ERRORS} is
"yes". ${PKG_FATAL_ERRORS} defaults to "no" to preserve the
existing behavior of install scripts by mk/pkginstall.
Add definitions for the gtk-update-icon-cache(1) command to the
script header template, and a makefile fragment that creates the
data file for the "icon_themes" package task if ${ICON_THEMES} is
"yes" in the package Makefile.
Also bump pkgtasks dependency to version 1.12 for the "icon_themes"
package task and compatibility with pkgsrc/mk/pkginstall.
A full dependency on the "pkgtasks" package will be added if a
non-empty data file is generated by the framework.
This framework is not yet hooked into bsd.pkg.mk, pending some
other changes.
