The ip6tables-legacy metapackage was renamed to ip6ables-zz-legacy.

Remove a few features that became enabled by default since OpenWrt 19.07.
Disabling CONFIG_RELAY also reduces RAM usage.

Remove kernel symbols which are not required for Gluon.

Gluon still uses firewall3 and iptables, so remove dependency on
nftables.

Jool can be built without error on 22.03. Remove this workaround.

A helper script is introduced to get the version from `git describe`.

These config changes are not necessary anymore, as it's now the default
behavior.

All targets now use OpenWrt device abstraction. Thus, all targets now
can be built using a per-device RootFS.

GLUON_AUTOUPDATER_BRANCH and GLUON_AUTOUPDATER_ENABLED should be set
separately now.

The new options are CONFIG_GLUON_AUTOUPDATER_BRANCH and
CONFIG_GLUON_AUTOUPDATER_ENABLED and allow to control the default branch
and default enable status separately.

The `or ''` fallback in targets/generic is removed, as GLUON_ENV will
set all variables in GLUON_VARS, making previously non-existing
variables exist with an empty value.

Normally, we build all nonshared packages (which includes all kernel
modules) to generate an opkg feed for later package installations by
users. On targets without opkg, this just wastes time - disable it.

(cherry picked from commit b3edfd29)

Normally, we build all nonshared packages (which includes all kernel
modules) to generate an opkg feed for later package installations by
users. On targets without opkg, this just wastes time - disable it.

This change stores a Kernel with Debug-Symbols for the current
architecture in a new output directory '<outputdir>/debug'.
This allows a developer or operator of a network to store the kernel
along with the actual images. In case of a kernel oops the debug
information can be used with the script
'scripts/decode_stacktrace.sh' in the kernel source tree to get the
names to the symbols of the stack trace.

OpenWRT already provides the CONFIG_COLLECT_KERNEL_DEBUG -option that
creates a kernel with debug-symbols in the OpenWRT output directory.
This change enables this option and copies the generated kernel to the
gluon output directory.

target_config.lua and target_config_check.lua don't pass a table of
callbacks anymore, so target_config_lib.lua can by simplified by moving
all the code that was in the returned function to the toplevel.

So far, we were using a sort operation on the generated .config to
implement precedence of =y packages over =m, and =m over unset.
Unfortunately, this sort not only used for packages, but for all config
lines. This made it impossible to override settings from targets/generic
in a target config when the new setting was sorted before the generic
setting.

To fix this, track configurations by their keys, so we can properly
override config keys that were set before. Value-based precedence is
only preserved for package configuration.

The config() and try_config() calls always take key and value as
separate arguments now. Strings are quoted automatically; the values
true, nil and false map to y, m and unset for tristate options. config()
can take an optional third argument to override the error message to
display when the setting fails to apply.

All existing target configs generate the same .config with the old and the
new code. The new code is also a bit faster on targets with many devices.

In OpenWrt 19.07, the block size was increased to 1024KiB for "tiny"
devices by default to save flash. Unfortunately, this also significantly
increases the cache memory required by squashfs.

In my test, the increased block size reduced the image size by ~64KiB,
but increased the RAM usage by ~2.6MiB. As most tiny devices have only
32MiB of RAM, this is not a reasonable tradeoff.

The ar71xx-generic target already defines an even lower block size of
64KiB.

This is unused by Gluon.

Fixes: c3435607 ("generic: increase RootFS size when GLUON_DEBUG is enabled")

This increases the size of the root filesystem when GLUON_DEBUG is
enabled. Otherwise, the filesystem is too small.

Closes #1907

This is necessary, as wpad-basic conflicts with hostapd-mini.

The old bash-based parsing code was way too complex. Replace it with Lua.

By passing the package name through merge_packages, it becomes possible to
override the package choice in GLUON_SITE_PACKAGES again, for example:

	GLUON_SITE_PACKAGES += -hostapd-mini hostapd

kmod-jool build is broken with current kernel 4.14.y.

modules.sh can't depend on openwrt/feeds.conf.default, otherwise the
initial update will fail.

kmod-usbip is broken since the last kernel update.

As the default package list is now handled using the 'packages' directive,
explicit wpad-mini removals in target definitions can be dropped.

This, together with a new try_config directive, will allow checking the
generic config and make it more flexible.

This reverts commit 819758f4.

A proper fix is now available, therefore reverting this workaround.

LEDE has sha256sum enabled by default.

This reverts commit dcff6802.
