Add gprs_ns2_fr_connect2() and change gprs_ns2_fr_connect() to
be similar to gprs_ns2_ip_connect() and gprs_ns2_connect2().
This is an API break but there wasn't yet a release with NS2.

Every bind will have a unique name. Add a name argument
to all bind creating functions and require them to be unique.

A NS dialect describes how the NS Entity interacts with
different virtual circuits. E.g. ipaccess use reset/block on udp
and is a dynamic connection.
A single NS Entity can only support one dialect. This can be later
used to protect a NS Entity against dynamic NS virtual circuits of a
different type.
It further allows a bind to support multiple dialects at the same time.

When opening the socket, use ETH_P_HLDC to restrict the socket to
packet received on HLDC interfaces. This avoids packets from random
other (ethernet, ...) interfaces to appear before we can bind()
it to the actual hdlc-net-device we're interested in.
We still are racing against other HLDC net-devices, but those have
lower PPS and throughput ratese as 1G/10G or even higher speed ethernet
devices that might exist on the same machine.

An AF_PACKET socket will immediately receive packets of _all_ interfaces
until it is bound to one specific interface. This introduces a race
condition between the socket() and the bind() syscall.
Let's use the ifindex passed for each packet in recvmsg() to drop
any packets received for other interfaces.

It's not needed because net/if.h already include
the required parts. Furthermore the linux/if.h generates
a compiler error in combination with net/if.h on older systems
(e.g. debian jessie)

We use the newly-introduced libmnl integration of libosmocore in order
to receive netlink events from the kernel on link state changes.
If one of "our" interfaces changed link state, we report this in the log
and also store it within the "bind".

Even it was in theory possible to mix NS-VC ll types within
a NSE. This is an unrealistic configuration.
Further more to select the correct load sharing mechanism
the NSE must know the correct link layer.

Add support for frame relay over dahdi hdlc device.
It's supporting lmi by q933 and supports both
SGSN and BSS.
