The fd is not valid anymore after close() call, so let's set it to a
clearly invalid value, to avoid confusion on closed_cb() users
attempting to use the fd get info about the socket at that time.

This is useful for users of the API which need to keep forwarding the
msgb to lower layers which may need prepending a new header to the msgb,
like osmo-bts with l1sap.

Until now, the osmux_out_handle was allocated by the client, and passed
to the API to initialize it. This makes it really hard to improve the
implementation without breaking the ABI.
Let's break the ABI now one last time (hopefully) by allocating the
struct through an API. With only this change, the already built users
(osmo-mgw, openbsc) can still work fine, since there's no change on the
struct osmux_out_handle. However, they will somehow break next time the
struct is changed until they are ported to the same API (easy to do).

Those APIs where deprecated 4 years ago (end of Aug 2018), and they have
not been used since around that time. Hence it can be considered safe to
drop them, since they only make the whole code more complex to
understand.
API osmux_xfrm_output_init() is left since openbsc.git is still using
it.

The check was wrong for format types containing extra bits not aligned
to byte boundaries, such as FT7 (AMR Code 12.20, 244 bits, 31 bytes).
if the source has 1-6 extra bits, they can be fit with one less byte
when shifting 10 bits to the left.
Change-Id: I0552d727585886d25f613e64ca815fb6dcd53f25
The proper order is CMR(4)+F(1)+FT(4)+Q(1).
Hence, FT is 3 least significant bits of first byte and 1 most
significant bit of secont byte.

This commits adds a generic mechanism for applications to validate
support for SAPs and specific versions of them.
A new special SAPI is introduced to manage inbound control messages for
the protocol.
In that SAPI a new primitive HELLO.req/.cnf is added to negotiate
support for versions of any given SAP.
The idea is that the client upon connecting submits a HELLO.req(SAP,
VER) for each SAP it plans to use, including the version of the special
CTL SAPI itself (preferrably to be checked first).
Upon receiving such a message, osmo_prim_srv handles it using a special
path, which ends up calling the user provided rx_sapi_version_cb(SAP,
VER). In there, the user can either:
* Accept the version (return same VER value)
* Reject the requested version but propose another candidate version
(return some positive VER value other than received VER). In this
case, the client can decide whether to request another VER or close the
connection.
* Reject the proposed version and close the connection.

This new module allows easy exchange of osmo_prim based data types over
IPC communication (UD socket supported only so far), by replacing the
osmo_prim_hdr struct with a serialized header when submitting/receiving
it from the IPC socket.
This patch introduces the server side of the UD socket, but the client
side can easily be introduced in the same file whenever needed.

The for loop in osmo_amr_bwe_to_oa, that converts the body part of the
AMR payload runs one byte too far. This may cause that some of the
padding bits in the end are not set to zero. The loop is designed to
convert n-1 bytes and the nth byte is done separately at the end.

Size of a single AMR frame doesn't always shrink by a byte when
converted from octet-aligned to bandwidth-efficient mode. It does
shrink for AMR modes 2, 3, 4, 6, and 7 but doesn't shrink for
AMR modes 0, 1, 5, and SID frames because we only remove 6 bits.
So old code generated truncated AMR packets for those AMR modes.
This patch fixes the length calculation by properly counting bits.
Proper bit counting is also bringing us one small step closer to
properly handlig multi-frame AMR packets.

New define is available since libosmocore 1.1.0, and we already require

It makes a lot more sense calling it this way since it matches the state

It's not really needed right now from logic point of view, since we
reused NONE for that. But it makes logging and logic clearer, and will
make it easier if we decide to move it to FSMs at a later point in time.
Other state value_string names are also modified with its whitespace
removed since anyway we'd need to change them to match WAIT_RECONNECT
length. Let's drop the space because imho it's not that useful and
anyway if we move to FSMs at some point then we won't have them anyway.

With previous state, osmo_stream_cli_close() could be called from
osmo_stream_cli_open()(), and in that case state was kept as NONE while
ending up with an associated fd being registered in the select loop.
As a result, osmo_stream_cli_fd_cb() could be called while in state
NONE, which was not expected and would simply return without modifying
fd state flags, causing it to be called again and again.

It should not happen anyway because no fd should be active if state is
NONE, but still it's an extra check.

Similar to what we do in libosmocore already, we want to
deterministically enable or disable support for the feature without
having into account if the system has a libsctp. If libsctp is missing
and support is enabled, then fail.
Extra checks are also added:
* Check netinet/sctp.h header
* Check libosmocore was built with libsctp support (API
osmo_sock_init2_multiaddr() we require).
* In stream.c make sure it can be built without HAVE_LIBSCTP, and that
set_addrs() fails for more than 1 address (since that feature is only
supported through osmo_sock_init2_multiaddrs()).
