libosmo-mgcp-client: fix debian, make self-contained
Add mgcp_common.h to libosmo-mgcp-client, to not need to share a header file
with libosmo-legacy-mgcp (nor the upcoming libosmo-mgcp). Both libraries use
the enum mgcp_connection_mode (and a for-loop macro and a string mangling
function), so far declared in mgcp.h, and both mgcp-dev and mgcp-client-dev
debian packages would require this header file to be installed. So far the
mgcp-client-dev lacks this header file, which causes the osmo-msc debian
package to fail building. Ways to solve:
- If both -dev debian packages installed the same header file in the same
place, they would conflict if ever installed at the same time.
- mgcp-client-dev can depend on mgcp-dev, but it seems bad to keep such a large
dependency for just one enum and two helpers.
- Instead, this patch solves this by copying the few definitions to
libosmo-mgcp-client.
Once libosmo-mgcp-client has its own copy of those definitions, it is
fully self-contained and depending builds (osmo-msc deb) will succeed.
Copy the few actually common definitions to new header
<osmocom/mgcp_client/mgcp_common.h>. The nature of this .h is that it may be
shared with future libosmo-mgcp without causing linking problems.
Remove libosmo-legacy-mgcp/mgcp_common.c file from the build of
libosmo-mgcp-client, no longer needed.
Add to new mgcp_common.h:
- enum mgcp_connection_mode;
- for_each_non_empty_line() macro.
- mgcp_msg_terminate_nul() as static function. Its complexity is just above
your average static inline, but being inline is a way to use it in both mgcp
and mgcp_client without linking problems.
Replace for_each_line() use in mgcp_client with for_each_non_empty_line()
(for_each_non_empty_line() replaces for_each_line() and uses strtok_r() instead
of a local reinvention).
mgcp_connection_mode_strs are actually only used in libosmo-mgcp-client, so
rename to mgcp_client_ prefix and move to mgcp_client.c.
BTW, the future plan for upcoming libosmo-mgcp is to use the identical header
file, and keep only one copy in the git source tree. The second copy may be
generated during 'make', to avoid code dup while having two distinct headers.

Initially implement the new osmo-mgw and libosmo-mgcp
Leave the old osmo-bsc_mgcp and libosmo-legacy-mgcp as it is; on a copy thereof
(added by a previous commit), apply changes to initially implement the new
osmo-mgw.
Adjust build system and debian packaging to accomodate the new libosmo-mgcp and
osmo-mgw.
The main differences:
*) use a list to manage rtp connections.
Aggregate all rtp related information inside a single struct.
Use a linked list to manage the both connections (net and bts).
The idea behind using a list is that we might support conference
calls at some later point.
Store the linked list in struct mgcp_endpoint, have a private linked
list for each endpoint. The list contains connection items which are
implemented in struct mgcp_conn. A connection is allocated and freed
using the functions in mgcp_conn.c. A connection is allocated on the
reception of a CRCX command and freed with the reception of a DLCX
command.
*) remove external transcoder feature
Fortunatelly the external transcoder feature is not needed
anymore. This patch removes the related code.
*) vty: get rid of CONN_BTS and CONN_NET
Since the new connection model does not make a difference
between BTS and NET connections the VTY should not use
the fixed CONN_BTS and CONN_NET constants.
- Handle the conns list inside the endpoint directly
- introduce function to dump basic rtp connection info
- introduce human readable names for connections
Parts of the code adjusted to use generalized connections instead of explicit
BTS/NET ones:
- teach mgcp_send_dummy() to send dummy packets to any RTP connection
- network: generalize mgcp_bind_net/bts_rtp_port()
- network: generalize mgcp_send()
- tap: generalize call tapping feature
- stat: generalize statistics
- Replace rtp_data_net() and rtp_data_bts() with generalized rtp_data_rx()
*) mgcp_protocol.c fixes:
- check ci string before it is converted:
In case of missing ci, a nullpointer is delivered to strtoul().
Add a function that takes ci, checks it and converts it to an
uint32_t. Use the return code to react on missing ci.
- output error message on missing CI.
- when parsing the mode, print log message when mode is missing.
- use mode_orig when mode is missing.
- fix ptime formatstring to use %u rather than %d.
- cosmetic: log when connection is deleted on DLCX.
- change loglevels of CRCX, MDCX, DLCX events from DEBUG to NOTICE.
*) mgcp_test
- apply rename of strline_r() to mgcp_strline().
- MGCP command macros:
- Add 'I: 1' parameters.
- Use proper port numbers:
from m=audio 0 RTP/AVP 126
to m=audio 16002 RTP/AVP 128
- Change ptime to 'a=ptime:40' because this is what the MGW currently
returns. CRCX generally feed a ptime:40 and this is expected to be
returned.
- struct mgcp_test: Use only one ptype, there are no explicit BTS and NET
endpoints anymore.
Hence remove one column from tests[].
- test_messages():
- Enable: remove '#if 0'
- Remove concept of BTS and NET endpoints: test only one conn, as they are
now interchangeable anyway.
- remove endpoint init, now done internally.
- add false asserts in error cases.
- test_retransmission():
- remove endpoint init, now done internally.
- add false asserts in error cases.
- test_packet_error_detection():
- Remove concept of BTS and NET endpoints: test only one conn, as they are
now interchangeable anyway. Use arbitrary conn ids (e.g. 4711).
- remove endpoint init, now done internally.
- add false assert in error case.
- Assert that a conn really vanishes on DLCX, previously the conn would
remain and just be unused, now it is actually discarded.
- test_no_cycle()
- Remove concept of BTS and NET endpoints: test only one conn, as they are
now interchangeable anyway. Use arbitrary conn ids (e.g. 4711).
- test_no_name()
- Enable: remove '#if 0'.
- remove endpoint init, now done internally.
- add false assert in error case.
- mgcp_test.ok: adjust expected results to status quo:
- We now see two dummy packets instead of one, now sent to both sides because
we don't know of BTS or NET side. (maybe drop dummy packets later...)
- packet duration, conn mode: now sane defaults show instead of unset.
- various whitespace and formatting changes from lindent.
