Some users report that DAWN sometimes crashes after a while. Mostly
this happens after the new update has been rolled out.
Since I would not like to go back to the older version, I add as
a workaround for now that DAWN automatically respawned.

Includes:
- dawn_uci: fix crashing when uci config is received
- tcpsocket: add option to add server ip
A new config option allows to add a server ip
option server_ip '10.0.0.2'
However, this server does not send anything back. Therefore it is not
possible to change the node configuration. This will probably be added
soon. The main goal of this commit is to allow monitoring of all nodes
in a network with DAWN, e.g. clients, channel utilization, ...
Also a network option (3) has been added which allows to use TCP but
not to announce your daemon in the broadcast domain. This allows you to
create a monitor-only node that holds only the local information and
forwards it to the central server.
A monitor-only node could be configured like
option server_ip '10.0.0.1'
option tcp_port '1026'
option network_option '3'
Another possible config is
option server_ip '10.0.0.1'
option tcp_port '1026'
option network_option '2'
Here, the node shares information with a central server, which can be
located outside the broadcast domain. Nevertheless, it also shares
information within its broadcast domain and can therefore perform
client steering.

test_storage: fix compilation with musl 1.2.0
datastorage/test: improve scalability and performance
datastorage: fixed use of wrong client search
general: add memory auditing
memory auditing: bug fixes to memory auditing and hearing map
datastorage: fixes to linked list handling
tcpsocket: fix read callback function and arbitrary memory allocations

Furthermore, you can now dump the memory usage by sending a SIGHUP to
dawn process.

I tried Dawn and it whined at me because it didn't understand its
own packets from a different-endian host.

If set_hostapd_nr config flag is set, dawn will insert the nr reports
to allow the hostapd to answer to nr requests from clients.
Improve the synchronization of rcpi and rsni in the network.
Further, clients with bad 802.11k were sending beacon reports with
bssid 00:00:00:00:00:00. Catch those corner cases.

DAWN has a race condition with umdns that prevents dawn from surviving
a reboot.
Increase procd start and stop of dawn to 81.
Further, network is sometimes not ready. Add utimer to check if socket
binds correctly.

Dawn is a decentralized WiFi controller.
Just install dawn and the APs will find each other via umdns.
They periodically exchange information about connected clients, wireless
statistics and other needed information. With that, the daemon load
balances clients between different APs through association control.
Further, the daemon exposes through ubus the hearing map and the
complete wireless network overview. The hearing map is the list of all
probe requests seen from a client from all APs that are running the
controller.
Hearing map:
ubus call dawn get_hearing_map
Network overview:
ubus call dawn get_network
Dawn has a graphical user interface called luci-app-dawn. With that, the
load balancing and other useful settings can be controlled.
