Attempt to parse each src/dst leg only once (which is a JSON document
these days) and use the same logic for determining whether to create a
CDR for both intermediate and final CDRs.

The MySQL INSERT statements to move processed Redis acc records from
Redis to the respective backup/trash MySQL tables are always issued
within a MySQL transaction (med_handler via medmysql_batch_start), but
the deletions from Redis were done immediately. Therefore if mediator
were to abort within a processing loop, the MySQL transaction would be
rolled back after the entries had already been deleted from Redis,
therefore losing the acc entries.
Solve this by using an internal queue for Redis entries to hold the
lists of entries to be deleted until the MySQL transaction is commited.

Use a struct with globally defined instances instead of a literal string
name to distinguish the two destination tables. This makes it possible
to unify record handling between the two tables.

This makes it possible to trace which CDR record was created from which
acc records and at which point.

json_tokener_parse returns a newly created JSON object (tree) which must
be freed by decreasing the ref count before the variable goes out of
scope.

The `cdr_index` variable already tracks the number of created CDRs, as
it points to the slot for the next CDR record to be inserted. It's
increased by one at the start of the processing loop, so if we end up
skipping over an entry after it's been increased, it must be decreased
again, which keeps the count intact and prevents empty CDR records from
being created.

* If there are multiple call leg acc records for a call, ones
that do not contain valid src + dst leg data (either JSON or th
old format), these acc records are skipped and intermediate cdrs
are created for the remaining records that contain valid src and dst
leg data

(cherry picked from commit c56b5f7503)
KeyDB notifies systemd prematurely about its readiness, while it might
still be loading data from persistent storage or from its replication
master. It refuses access to its databases during that time, so make
mediator sleep/retry a few times to handle this.

When processing acc records for a call that was the result of a REFER,
there will be two BYE records, one for the call itself without further
info in dst_leg, and another one for the original call that includes the
record for the REFER, with extra info in dst_leg that points back to the
original call. Skip the BYE with this extra info when processing record
so that it's still present when the other call (with the REFER) is being
processed.

Use the call ID from the contained JSON object in REFER records to
follow the call flow to the new call ID and look there for the matching
BYE record.

This allows us to fetch only specific records that we're interested in,
based on context, instead of all of them and then having to do a second
pass over them.

Instead of using two lists to keep the acc records (based on where they
were retrieved from) use only a single list for all acc records.
Make sure the list is only appended to in the functions doing the record
retrieval.
Since the list of acc records needs to be sorted only when records were
retrieved from Redis, change the return value of the retrieval functions
to indiciate whether this needs to be done, or -1 for error.

Use g_strdup_printf instead of sprintf+strdup
Include Redis key prefix in the first printf to avoid having to do
another sprintf
Use G_N_ELEMENTS() instead of hard coded array size
Do alloc cleanup only once at the end of the function
Use g_list_prepend instead of g_list_append to avoid repeated list
iterations

If we know the method of the Redis entry that we're deleting, we can
skip on trying to remove the entry from all possible pseudo-keys and
instead remove it only from the appropriate one.

With this we can directly use the method code for decision making

Use strdup/free for string fields in med_entry_t that are highly
variable in length. This elimiates future problems if one of these
fields ever has its length extended.
Use g_strdup as it guarantees a non-NULL return value.

Using an array in this context (to return a list of acc records) is
mostly pointless as it wastes memory and incurs the additional overhead
of having to initialise the array and an extra layer of copying strings
around. This also ultimately allows us to dynamically append to the list
of acc records without having to reallocate the array.

We are migrating from redis to keydb so for now we need to support both
so we should not depend on specific key-value storage in unit file but
should use database.key_value.flavor value in override file.
But we can't redefine dependencies in override file just add additional
ones. So remove it from unit file.

As the number of subscribers grows, the current approach of doing a full
table dump of the subscribers DB and caching it in memory becomes less
and less feasible. The new approach is to simply do a straight DB query
for each subscriber as records are processed, and then cache the result
in memory for a little while.

ubuntu-20.04 doesn't provide debhelper-compat (= 13), therefore fails with:
| The following packages have unmet dependencies:

| E: Unable to correct problems, you have held broken packages.
Let's switch from ubuntu-20.04 to ubuntu-latest, which
currently still points to ubuntu-20.04, but should reduce
our maintenance efforts.
Furthermore enabled the ubuntu-cloud-archive/yoga-staging PPA,
which provides a backport of debhelper v13:
