mk/misc: make configuration for show-all targets more configurable

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).

# $NetBSD: bsd.options.mk,v 1.74 2018/11/30 18:38:19 rillig Exp $
#
# This Makefile fragment provides boilerplate code for standard naming
# conventions for handling per-package build options.
#
# Before including this file, the following variables can be defined:
#
#	PKG_SUPPORTED_OPTIONS
#		This is a list of build options supported by the package.
#		This variable should be set in a package Makefile.  E.g.,
#
#			PKG_SUPPORTED_OPTIONS=	kerberos ldap ssl
#
#	PKG_OPTIONS_VAR (must be defined)
#               The variable the user can set to enable or disable
#		options specifically for this package.
#
#	PKG_OPTIONS_OPTIONAL_GROUPS
#		This is a list of names of groups of mutually exclusive
#		options.  The options in each group are listed in
#		PKG_OPTIONS_GROUP.<groupname>.  The most specific
#		setting of any option from the group takes precedence
#		over all other options in the group.  Options from
#		the groups will be automatically added to
#		PKG_SUPPORTED_OPTIONS.
#
#	PKG_OPTIONS_REQUIRED_GROUPS
#		Like PKG_OPTIONS_OPTIONAL_GROUPS, but building
#		the packages will fail if no option from the group
#		is selected.
#
#	PKG_OPTIONS_NONEMPTY_SETS
#	       This is a list of names of sets of options.  At
#	       least one option from each set must be selected.
#	       The options in each set are listed in
#	       PKG_OPTIONS_SET.<setname>.  Options from the sets
#	       will be automatically added to PKG_SUPPORTED_OPTIONS.
#
#	PKG_SUGGESTED_OPTIONS (defaults to empty)
#		This is a list of build options which are enabled by default.
#
#	PKG_OPTIONS_LEGACY_VARS
#               This is a list of USE_VARIABLE:option pairs that
#		map legacy /etc/mk.conf variables to their option
#		counterparts.
#
#	PKG_OPTIONS_LEGACY_OPTS
#		This is a list of old-option:new-option pairs that
#		map options that have been renamed to their new
#		counterparts.
#
#	PKG_LEGACY_OPTIONS
#		A list of options implied by deprecated variables
#		used.  This can be used for cases that neither
#		PKG_OPTIONS_LEGACY_VARS nor PKG_OPTIONS_LEGACY_OPTS
#		can handle, e. g. when PKG_OPTIONS_VAR is renamed.
#
#	PKG_OPTIONS_DEPRECATED_WARNINGS
#		A list of warnings about deprecated variables or
#		options used, and what to use instead.
#
#	If none of PKG_SUPPORTED_OPTIONS, PKG_OPTIONS_OPTIONAL_GROUPS,
#	PKG_OPTIONS_REQUIRED_GROUPS, and PKG_OPTIONS_NONEMPTY_SETS are
#	defined, PKG_OPTIONS is set to the empty list and the package
#	is otherwise treated as not using the options framework.
#
#
# Optionally, the user may define the following variables in /etc/mk.conf:
#
#	PKG_DEFAULT_OPTIONS
#               This variable can be used to override default
#		options for every package.  Options listed in this
#		variable will be enabled in every package that
#		supports them.  If you prefix an option with `-',
#		it will be disabled in every package.
#
#	${PKG_OPTIONS_VAR}
#		This variable can be used to override default
#		options and options listed in PKG_DEFAULT_OPTIONS.
#		The syntax is the same as PKG_DEFAULT_OPTIONS.
#
# After including this file, the following variables are defined:
#
#	PKG_OPTIONS
#		This is the list of the selected build options, properly
#		filtered to remove unsupported and duplicate options.
#
#	PKG_DISABLED_OPTIONS
#		This is the list of the disabled build options; this is
#               the complement of PKG_OPTIONS.
