Allow to configure multiple servers and connect. Introduce a new VTY
node to allow multiple servers. Add an explicit connect. Do not put
the main connection into the same list but assume it exists.

If we want to have multiple servers we should not block when trying to
connect to one of them. Enable non blocking mode and handle the fd
specially until it is connected. E.g. on failed connect the read will
become readable but fail, otherwise it becomes writable.
Clear the write queue to make sure that the link data is sent first.
We might be able to introduce a osmo_wqueue_prepend.

Take out various fields into a new connection class. We will have the
option to connect to multiple servers.

Make the priority configurable, load DH params, allow to specify
certificates or anonymous operations.

Add simple vty command to enable tls per client or not. We still
need a lot more tls commands for the server.
Change-Id: I583b7d5c999ed01c135882895fb2a8f04739ad00
Using tls priority of NORMAL:+ANON-ECDH:+ANON-DH already allows a
client to connect to a server and protect the data using tls.
Generate the dh params on load (and do that for the client right
now as well) but that will go away soon.

In preparation of TLS let's not call close_connection from
within the dispatch but return an error and then close the
connection from the outside.

We are only reading from the socket and never write but the osmo_tls
code is integrated with it. We will never write and the queue size is
set to 0. Simplify the read_cb.

Use GNUtls because it is GPL compatible and instead of mbedTLS seems
to have a working non-blocking I/O integration. GNUtls has various
issues that could not be resolved easily:
* Pick spdy as sub protocol
* gmt_time not randomized
* private key loaded to RAM (but not verified)
This is the beginning and not the end. Client support might need more
work with actual tls verification. Maybe more manual x509 cert
verification is needed and maybe client certs don't work at all. I try
to ignore renegotiation as I threw away the key.
Reload x509 creds and keys as they might have changed from one
connection to another.

Add the basics for getting a picture what a client and the server
is doing. We need to create unique descriptions as the code is
working with names and not numbers for clients.

Add more counters and start counting them when reading from the
PCAP library and when trying to write to the socket.

To allow easily extracting or streaming the data to an external
analysis system, zeromq can be configured (and reconfigured). The
system works as fire and forget and no loss detection is present.
A simple go based client application is provided to subscribe to
the publisher.

We might only want to centralize the data streams but handle the
data differently. This will be combined with an upcoming ZeroMQ
publisher feature to broadcast all events out.

We need to convert the 64bit timeval on a 64bit userspace (or on
OpenBSD) into a 32bit truncated value for being able to write the
file. This means we have 2038 issue here?
The 2000 as a number is too small. Modern networks can have a
higher MTU (up to 9000). Take this number and assume there is
a big header in front of it.
Allow to inspect UDP messages and check for GPRS, NS, BSSGP
and then filter LLC frames. Parsing the vL datastructure with
the libpcap syntax is a pain. It could be done using BPF but
we do not want to use bpf asm to specify the entire ruleset.
I looked into using libepan/libwireshark but this has memory
issues and is painful too. So let's parse UDP, NS, BSSGP using
the info we already have. I tried a bit of editcap to generate
a bit of broken data. The length check might still be bad.
I used my crash_20100602.pcap file to count the LLC frames we
detect and compare that to wireshark it ended with the right
number.
pcap add-filter gprs
can be used to enable the new filtering option after the OS
has received the packet.
Fixes: ONW#1314
The connect0_bind1 parameter has been replaced by a generic flag
parameter. With this patch osmo-pcap works (only) with versions of
libosmocore 0.3.2 or newer - configure.ac changed to reflects that.
