Set sysctl fs.suid_dumpable = 2
This allows suid processes to dump core according to kernel.core_pattern
setting. LEDE typically uses suid to drop root priviledge rather than
gain it but without this setting any suid process would be unable to
produce coredumps (e.g. dnsmasq)
Processes still need to set a non zero core file process limit ('ulimit
-c unlimited' or if procd used 'procd_set_param limits
core="unlimited"') in order to produce a core. This setting removes an
obscure stumbling block along the way.
>From https://www.kernel.org/doc/Documentation/sysctl/fs.txt
suid_dumpable:
This value can be used to query and set the core dump mode for setuid
or otherwise protected/tainted binaries. The modes are
0 - (default) - traditional behaviour. Any process which has changed
privilege levels or is execute only will not be dumped.
1 - (debug) - all processes dump core when possible. The core dump is
owned by the current user and no security is applied. This is
intended for system debugging situations only. Ptrace is unchecked.
This is insecure as it allows regular users to examine the memory
contents of privileged processes.
2 - (suidsafe) - any binary which normally would not be dumped is dumped
anyway, but only if the "core_pattern" kernel sysctl is set to
either a pipe handler or a fully qualified path. (For more details
on this limitation, see CVE-2006-2451.) This mode is appropriate
when administrators are attempting to debug problems in a normal
environment, and either have a core dump pipe handler that knows
to treat privileged core dumps with care, or specific directory
defined for catching core dumps. If a core dump happens without
a pipe handler or fully qualifid path, a message will be emitted
to syslog warning about the lack of a correct setting.

There already exist static assignment of uid/gid 65533 in packages feed
and we have nobody/nogroup taking 65534 as their ids. Let's change the
pid of dynamic assignment to start from 65536 so that the two assignment
scheme will not collide with each other
While at it, fix the scan command checking existence of uid/gid

Rework the network_get_ipaddr6() and network_get_ipaddrs6() functions to

We always want to support staged upgrades now, so it's better to include
upgraded into the main package. /lib/upgrade/nand.sh is moved to
base-files.
The procd-nand-firstboot package is removed for now, it may return later
as a separate package.

Image metadata is in JSON format and contains a list of supported
devices, along with version information that could be displayed by a UI

/etc/os-release is the standard distribution release information
file, therefore add it (and image configuration options for
fields not previously present in LEDE). Once it is deemed
reasonable the non-standard openwrt_release, openwrt_version,
and device_info files could be removed (that is with this patch
we consider them deprecated in favour of the standard file).

If the user sets any preinit options in .config, the wrong path may get
applied due to wrong default value in image-config.in and due to Makefile
writing also the unchanged options into 00_preinit.conf

path set by r47080. Also modify the fall-back default in Makefile.

Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.
I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.
However, I can not garantee that I always picked the correct information
and/or did not miss license information.

like network_get_ipaddrs6 does. If ipv6-address was empty the function
did not return the first ipaddr even if the list was non-empty.
