For the GSUP clients in upcoming D-GSM enabled osmo-hlr, it will be necessary
to trigger an event as soon as a GSUP client connection becomes ready for
communication. Add the osmo_gsup_client->up_down_cb.
Add osmo_gsup_client_create3() to pass the up_down_cb in the arguments. Also
add a cb data argument to populate the already existing osmo_gsup_client->data
item directly from osmo_gsup_client_create3().
We need the callbacks and data pointer in the osmo_gsup_client_create()
function right before startup, because this function immediately starts up the
connection. Who knows whether callbacks might trigger right away.
Because there are so many arguments, and to prevent the need for ever new
versions of this function, pass the arguments as an extendable struct.

Several parts of OsmoMSC (e.g. GSM 04.11, 09.11, etc.) are dealing
with GSUP message encoding and sending towards OsmoHLR. In order
to avoid code duplication, let's have a shared function here.

Add a new API which allows creating a GSUP client connection with
more identification information than just a unit name. Instead of
being selective about which idenfifiers callers may use, allow
callers to pass a full-blown struct ipaccess_unit. This allows
applications to use entirely custom identifiers on GSUP client
connections.
This change is a prerequisite for inter-MSC handover because MSCs
will need to use unique identifiers towards the HLR, which isn't
very easy to do with the old osmo_gsup_client_create() API. While
it's always been possible to pass a unique unit_name, this is not
as flexible as we would like.
The old API remains for backwards compatibility.
struct osmo_gsup_client grows in size but is allocated internally
by the library; old calling code won't notice the difference.

As we're moving this to a common/shared library now, we need to use
the osmo_ namespace prefix for symbol names, struct/type names and
constants.

This imports the code from osmo-msc 6afef893e17bce67e4d4119acd34d480ed03ba77
with minimal changes to make it compile. Symbol renaming ot osmo_
prefix is done separately in a follow-up patch to have a as-clean-as-possible
import first.
