Whether a bit-field is signed or unsigned is implementation specific, so
we should be explicit about this.

On Debian buster the latter contains transitive dependencies in Libs,
instead of in Libs.private, which leaks linking implementation details.

We need readonly access to /dev/urandom, otherwise the rand()
calls might fail, as seen in kamailio-config-tests.

In carrier environments we have foreign DB hosts
configured in /etc/ngcp-mediator/ngcp-mediator.conf,
therefore we can't easily apply IP address filtering.

We only ever go into the error handling code before malloc has
succeeded, which means ‘entries’ will always be NULL.

While MariaDB uses my_bool here, MySQL uses the standard bool type. Both

With the increased length of src/dst_leg strings, we must also increase
the buffer size for the insert string.
Did I mention that we should really move to dynamic strings here...

This is relevant for records coming from Redis, as the insertion into
the trash and backup tables is done from the strings kept in memory.

(cherry picked from commit 6e957e69b7)
/var/lock was deprecated with Debian/wheezy (see
https://wiki.debian.org/ReleaseGoals/RunDirectory), so
/var/lock/mediator.lock is actually /run/lock/mediator.lock.
Reflect this in the definition of MEDIATOR_LOCK_FILE.

Due to the movement of call transfer handling from sems pbx to
standard sems, in case of blind call transfer the BYE ACC is
generated with call_id suffix '_pbx-1_xfer-1' instead of '_xfer-1'.
To be more precise, currently we creates 2 ACCs for INVITEs:
- one without any suffix
- one with '_xfer-1" suffix
and just one for the BYE:
- with '_xfer-1' suffix
Mediator is able to use the BYE to close both the INVITEs
With the new implementation we creats 2 ACCs for INVITEs:
- one without any suffix
- one with '_pbx-1_xfer-1" suffix
and just one for the BYE:
- with '_pbx-1_xfer-1' suffix
The sinlge BYE record is not used to close both the ACC INVITEs.

Strings, in particular call IDs, that are coming from Redis are not
necessarily valid UTF-8 since Redis doesn't really do UTF-8. The MySQL
DB schema expects strings in valid UTF-8 however (even though call IDs
really should be raw binary strings), resulting in an error if an
UTF-8 invalid string is attempted to be inserted.
Solve this by verifying each string's UTF-8 correctness before inserting
it, and forcing it to be interpreted as the 100% permissive latin1
charset if it isn't.

Kamailio writes src_leg and dst_leg information of ACCs
in json format. Mediator has been adapted to read them
in this new format.
Due to that the size of src_leg and dst_leg has been
increased from char(256) to char (1024).
For backward compatibility the old format has been preserved
and used if the src_leg and dst_leg are not in json format.
This change is transparent for the final CDR's output.

In a cluster setup, intermediate CDRs might be written to a different
host than the final CDRs (central vs pair).

Since medmysql_flush_med_str() takes the handler from the
_medmysql_batch_definition structure, the last retrieved insert ID must
also be taken from the same handler.

Json function used to get MOS values has been slitted in
two: one to get the value from the json dict and one to clamp
it in order to have the final value between the desired
range of values.

medredis_fetch_records() allocates memory for 0 return records, which in
the calling code is understood as "no memory has been allocated",
leading to a slow leak. Returning early is correct as the mem block
pointer is set to NULL in this case.

We must distinguish between old-style acc records without an appended
branch ID (key ends in `:<ts>`) and broken new-stype acc records with an
empty branch ID (key ends in `:<ts>:`). Failure to do so results in
leftover entries in the DB that are never trashed and repeatedly
processed.

The db_redis module also writes simulated non-unique keys for acc
records, so we must use handle them appropriately when deleting the
keys, because otherwise we get leftover entries.
