It is not always necessary to add a host route for the gre peer address.

This introduces a new config option 'nohostroute' (similar to the
option introduced for wireguard in d8e2e19) to allow to disable
the creation of those routes explicitely.

This is a backport from OpenWrt master.

OpenWrt saves additional config (and other) files included with
list_changed_conffiles in /sbin/sysupgrade.

This is only active since openwrt-18.06, since before that it was
suppressed by missing opkg.

Since we expect to only save what is in sysupgrade.conf, remove the
additional file list (and thus regain pre-openwrt-18.06
behavior).

Note that with current firmware, both two versions of wget

When using IPv6 addresses (or DNS which has AAAA record) as endpoint,
add_host_dependency fails for some reason which causes the wireguard

to the interface.

At the moment sysupgrade via WebUI is broken on many devices.
This is reproducible: While the (few) status messages seem
normal, the device boots again with the old firmware.
Sysupgrade via SSH always works.

The sysupgrade call in upgrade.html directly uses the path of
the uploaded firmware file as argument. From several tests and
based on caught stdout/stderr from this line, it looks like haserl
deletes the uploaded firmware file due to a hidden trigger before
or even while it is processed by sysupgrade.

The easiest way to work around that is to just rename the file
before using it as argument to sysupgrade. This will preserve the
file DURING sysupgrade. If sysupgrade fails explicitly (status
code != 0), remove the file to provide sufficient memory for
another upload.

The buildscript knows two different types of patches, which are
applied to pulled-in repositories:

1. Feed patches
Those are applied as "GIT patches" to the relevant repos,
directly after those have been checked out.
They reside in subfolders of the build_patches folder, and
have to be selected individually and manually in the
buildscript.sh.

2. Build patches
Those are applied later in the process, just using the system
patch tool, and changing the $target directory.
All patches in the folder "build_patches/openwrt" are read
and applied automatically.

This is both inconsistent (two different types of patches in
the same dir) and annoying (feed patches have to be specified
by hand), especially for unexperienced developers.

This patch addresses this by:
- separating files into two dirs: build_patches and feed_patches
- automatically scanning feed patches and thus having similar
  experience for the user (I cannot think of a case where we
  provide a patch, but do not use it)
