When configuring osmo-mgw the user may choose an arbitrary trunk number
for the E1 trunk and sets a line number that must match the number of
the physical line that is used with the particular trunk. This is easy
to confuse, so lets add a note to the maual that mekes this clear.

We don't really care about the kernel style after all and the linter
complains about proper formatting, so remove all for-like macros so
we don't accidentally apply kernel style formatting.

This was previously broken and a free endpoint was requirted to dlcx *,
additionaly globally handling this is difficult due to different
response
codes, so just do it in the functions, they know best.

Do not turn some compiler warnings into errors by default. This patch
was added before --enable-werror was available.
We build with --enable-werror during development and in CI. If the code
is built with a different compiler that throws additional warnings, it
should not stop the build.
This reverts commit 34f012639d.

There is no obvious reason why we would want to complicate the code by
caching pointers, since pointer traversal is probably not a performance
bottleneck, and if it is we should rather take a look at our dozens of
linked lists first..

Usually only one MGCP client per application is present. Then the log
lines from mgcp_client.c will be distinguishable without additional
information. When the application is using a pool of MGWs, then the
various MGCP Client instances become hard to distinguish.
- Add a possibility to set a description (name) for each MGW pool
member. When no description is set, use the domain name.
- Output the pool member name on each log line in mgcp_client.c
and mgcp_client_pool.c

there is no obvious reason why the endpoints that belong to a trunk would
have the (global) config as parent context, you can't really have endpoints
without a trunk anyway.

They are mostly not even as large as the talloc header used to
dynamically allocate them, and they are also not "shared" by anything.

Trunk is safe, since it will not disappear sooner than the endpoints or

No need to complicate audio codes with pointers, our "usual" string is

Clang and gcc have different names for this, but the check fails without
-Werror since clang only warns about unknown args.
The previous check led to a lot of "unknown arg" spam while compiling

When the function mgcp_client_pool_vty_init is called with pool = NULL,
then it segfaults. Lets put an OSMO_ASSERT() on pool to make clear that
a pool must be present before initalizing the VTY on it.

At the moment the MGCP Client only supports one MGW per application.
Depending on the requirements of the application one MGW might not offer
the performance needed. Lets add support for an MGCP Client pool that is
backward compatible to existing applications.

The function init_socket has an arbitrary retry count when opening the
socket. After each retry the local port is incremented by one. The
intention behind this is to find a useable local port in case the
configured port is used by another process.
The maximum number of retrys is hardcoded. The upcomming MGW pooling
patch requires to set the maximum retry count.

The vty always checks if global_mgcp_client_conf exists. (there is also
an assert This check about global_mgcp_client_ctx).
global_mgcp_client_ctx and global_mgcp_client_conf are populated before
the VTY commands are installed. Unleass the caller uses the API wrong
and calls mgcp_client_vty_init with NULL pointers there cannot be a
problem with unpopulated pointers. Lets remove the checks as they are
not needed.

Depending on the usecase of osmo_mpcg_client it may be helpful to send a
DLCX to certain endpoints. Usually this would be a wildcarded endpoint
that resets the entire trunk to drop lingering RTP flows which may still
present after a restart/crash, but it might be also a group of specific
endpoints. The user may specify an arbitrary amount of endpoints where
the mgcp client will send a DLCX to. It does not matter if the endpoints
are wildcarded or not.

The rate counter and stats item groups, which are allocated in
mgcp_ratectr.c are freed using a talloc destructor that is set in the
context of the item we just allocated using the stats / rate counter API
functions. When we do that, we risk overwriting an already existing
talloc destructor. Lets instead implement own free functions and set
those as talloc_destructor from above (trunk and MGCP config)

The MGW domain name is usually checked while resolving the endpoint
after the trunk has been resolved. This was no problem before, but since
we allow wildcarded DLCX requests, which require only a trunk to work,
the check is not done correctly for wildcarded DLCX requests and invalid
domain names may slip through.
Checking the domain name earlier while the trunk is resolved makes sense
and it fixes the problem.
