Holger Hans Peter Freyther 8a8df80772 bsc/nat: Fix the structure of the identity request message
Unfortunately the basic structure of the response is broken.
There is a two byte length followed by data. The concept of
a 'tag' happens to be the first byte of the data.

This means we want to write strlen of the token, then we
want to write the NUL and then we need to account for the
tag in front.

Introduce a flag if the new or old format should be used.
This will allow to have new BSCs talk to old NATs without
an additional change. In the long run we can clean that up.

Nikola Kolev b9f45987b3 bsc: Fix compilation on FreeBSD
FreeBSD uses POSIX netinet/in.h for representing socket addresses
data types.

[Holger removed the #ifdef and changed the order of includes to
have specific ones first and system includes later]

Jacob Erlbeck e827812051 ipa: Use enhanced ipa_msg_recv_buffered() to cope with partioned IPA messages
The old ipa_msg_recv() implementation didn't support partial receive,
so IPA connections got disconnected when this happened.

This patch adds the handling of the temporary message buffers and uses
ipa_msg_recv_buffered().

It has been successfully tested by jerlbeck with osmo-nitb and
osmo-bsc.

Holger Hans Peter Freyther c1a8687cb8 bsc_msc: Add a name field to the MSC Connection to differentiate links
Assign a static name to a MSC Connection and use it. In case there
are multiple connections we can now more easily identify them.

This is only used for the NAT right now, the BSC could start to
name the various MSC connections too.

Holger Hans Peter Freyther e188010512 bsc: Allow to have a list of MSCs/MUXs to connect to
Be able to configure a list of destinations (duplicates allowed)
that will be tried in a round robin fashion. The change is in
the bsc_msc_connection to operate on a list. We achieve the
round robin nature with the same trick used in the paging code
to delete and append the current entry. The nat code was updated
to compile but one can only configure one destination.

Pablo Neira Ayuso 136f453dd2 src: use new library libosmogsm and new path to headers in libosmocore
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]

Harald Welte 9af6ddfcec License change: We are now AGPLv3+ instead of GPLv2+
The reason for this is quite simple: We want to make sure anyone
running a customized version of OpenBSC to operate a network will
have to release all custom modifiations to the source code.

Holger Hans Peter Freyther ca999a989d msc: Add msc ip-tos NR option for the BSC
Allow to set the TOS field via the VTY interface. The
SO_PRIORITY was not used as it has no effect on the
packets being sent (in contrast to the documentation).

Holger Hans Peter Freyther e47a91b86a bsc_msc: Add a connection timeout for the MSC.
When no one is listening our connection would get stuck
in the SYN_SENT state and we would be there forever.

Holger Hans Peter Freyther 8bdcf55b22 bsc_msc_ip.c: Create the GSM network earlier, send the reset on each connection
Create the GSM network at the end of the init, send the
GSM reset on each reconnection and close a small window
when we would send a SCCP msg before being authenticated.

For that we have introduced an authenticated into the bsc_msc
struct and will manage it inside the bsc_msc_ip.c

Holger Hans Peter Freyther baf2abe4c4 msc: Create a real interface for BSC MSC and start handling reconnects
Create a BSC<->MSC interface and use it for the BSC MSC IP and the
BSC NAT to reduce code duplication on handling reconnects to the MSC
and cleaning up the local state. The code is only partially tested
and will contain bugs. Currently both the BSC and the NAT will just
exit on connection loss and this way have the current behavior.
