Increase the version number and send the sizeof of the gsm_mncc
and the gsm_data_frame structure. Include the offsets of some
members as well to maybe identify ABI problems.
The reason we go through this is that we want to benefit from
the native ABI and don't want to force packed structs.
Send a hello packet down to the client with the version number
of the MNCC interface. The hello structure might be extended to
include the endianes, size of each structure, etc.
This will cause the remote end to read 0 bytes, which is interpreted as
if we cleanly closed the socket, making the remote end close their side
of the socket, which would lead to us closing our side of the socket,
so we should never send such a packet.
When we have no other MNCC connection but the registeration of the
new fd is failing we should not disable reading from the listen_fd
for ever as the situation might not be permanent.
libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]
