Only add neighbors with the same SSID to an interface's neighbor report.
While it is possible to offer roaming to a different SSID, it is often
not desired, while at least Apple devices limit the number of entries
they will use to 6.

Currenty, ap_array_get_ap returns an entry by matching just the bssid,
without checking if the SSID matches.
ap_array_find_first_entry does a binary search through the ap set
without cheking the SSID, which is bad, as the list is sorted by SSID
then by bssid_mac.
As a side effect, if you have more than one ssid, the network ap list
grows unbounded over time.

SSID_MAX_LEN is set at 32, which is the maximum allowed size of a SSID.
The strings holding SSIDs were set at that same size, which does not
allow for proper string termination.

The rrm_nr_get_own call returns an array. We need the 3rd value. We do
not need to call blobmsg_data before blobmsg_get_string to extract the
value. Additionally this causes strange behavior where an offset in the
string is accessed.
The datastorage-refactoring changes an already existing entry instead
of inserting and deleting it. However, it was forgotten to adopt
some information from the new probe entry.
The ht_capabilities and vht_capabilities are now synced correctly.
RCPI and RSNI is now correctly synced.
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 '3'
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.
It can happen that the callback is executed but there are 0 bytes to read. If this happens we leave the while-loop.

If not all of the message was in the stream after the header was read,
the next bytes remain in the buffer and only the header is removed from
the stream. The next time the callback is called, something that is not
a header will be interpreted as a header, resulting in arbitrary memory
allocations.

in luci-app-dawn, if eval_probe_req is not ticked, eval_probe_req would be -1.
however, in c language, !(-1) is false.
Since only zero in if statement is false, non-zero number is true.
