This integrates with netifd in order to provide STP/RSTP protocol support
in user space. It defaults to using RSTP for bridges with stp enabled.

Add a config option for json_script instead of unconditionally including
all json files in /etc/uhttpd in every uhttpd instance. This makes it
possible to configure a single instance with an unconditional redirect,
which currently renders all other uhttpd instances unusable.

Currently, when using multiple dnsmasq instances they are all assigned
to the same Ubus instance name. This does not work, as only a single
instance can register with Ubus at a time. In the log, this leads to
`Cannot add object to UBus: Invalid argument` error messages.
Furthermore, upstream 3c93e8eb41952a9c91699386132d6fe83050e9be changes
behaviour so that instead of the log, dnsmasq exits at start instead.
With this patch, all dnsmasq instances are assigned unique names so that
they can register with Ubus concurrently. One of the enabled instances
is always assigned the previous default name "dnsmasq" to avoid breaking
backwards compatibility with other software relying on that default.
Previously, a random instance got assigned that name (while the others
produced error logs). Now, the first unnamed dnsmasq config section is
assigned the default name. If there are no unnamed dnsmasq sections the
first encountered named dnsmasq config section is assigned instead.
A similar issue exists for Dbus and was similarly addressed.

Before this commit, it was assumed that mkhash is in the PATH. While
this was fine for the normal build workflow, this led to some issues if
make TOPDIR="$(pwd)" -C "$pkgdir" compile
was called manually. In most of the cases, I just saw warnings like this:
make: Entering directory '/home/.../package/gluon-status-page'
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found

bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found

[...]
While these were only warnings and the package still compiled sucessfully,
I also observed that some package even fail to build because of this.
After applying this commit, the variable $(MKHASH) is introduced. This
variable points to $(STAGING_DIR_HOST)/bin/mkhash, which is always the
correct path.

If the environment variable FILTER is set before compilation,
compilation of the ppp-package will fail with the error message
Package ppp is missing dependencies for the following libraries:
libpcap.so.1
The reason is that the OpenWrt-patch for the Makefile only comments
out the line FILTER=y. Hence the pcap-library will be dynamically
linked if the environment variable FILTER is set elsewhere, which
causes compilation to fail. The fix consists on explicitly unsetting
the variable FILTER instead.

dnsmasq v2.83 has a bug in handling duplicate queries which means it may
try to reply using the incorrect network socket. This is especially
noticeable in dual stack environments where replies may be mis-directed to
IPv4 addresses on an IPv6 socket or IPv6 addresses on an IPv4 socket.
This results in system log spam such as:
dnsmasq[16020]: failed to send packet: Network unreachable
dnsmasq[16020]: failed to send packet: Address family not supported by protocol
dnsmasq v2.84test3 resolves these issues.
