This should have been done in [1], but somehow I forgot about TRXD.

l1ctl_server_start() does not actually start the server, it simply
allocates memory and initializes it. l1ctl_server_shutdown() does
the opposite. Let's use more precise symbol names.

Calling l1ctl_server_shutdown() whenever the server is not initialized
will result in accessing uninitialized values. This can happen if we
goto exit before l1ctl_server_start() was called.
Initializing the server with zeroes is not an option, because we need
to initilize llist_head and osmo_fd structures with proper values.
Allocate and initialize struct l1ctl_server in l1ctl_server_start(),
deinitialize and free() in l1ctl_server_shutdown().

Ideally, FBSB procedure should be implemented as a state of trxcon's
FSM. For now let's simply move the related fields to trxcon_inst.
Remove l1ctl_shutdown_cb() as it's not needed anymore.

trxcon consists of the following three main components:
* the L1 TDMA scheduler (libl1sched),
* L1 interface (TRXC/TRXD over UDP),
* L2 interface (L1CTL).
In [1] and [2] the L1 scheduler was abstracted out from both L1
and L2 interfaces and separated into a library, so it does not
use the TRXC/TRXD nor L1CTL related API directly.
This change is the next step towards the goal of having all three
components abstracted from each other. Moreover, this patch brings
us closer to another goal of being able to support multiple L1CTL
connections (each having its own scheduler).
The idea is to give both L1 and L2 interfaces access to the
'trxcon_inst' structure, which basically groups all three components
mentioned above into a single piece. The end goal is to eliminate
direct interaction between the interfaces, and the scheduler, so that
one could easily replace TRXC/TRXD and/or L1CTL with something else.

Timeslot Number can never be negative, so let's use unsigned.
Rename the counter to 'tn' for consistency with other projects.

Using L1CTL specific structures as the primitive payload was a
beautiful hack in the early days of trxcon. But since we're
going to separate the scheduler into an interface independent
library, we have to introduce and use an abstract API.

Make l1sched_prim_alloc() private and call it from l1sched_prim_push().
This makes the API more convinient, because both functions are always
used together.

Using uint8_t makes it impossible to allocate primitives with payload
of size 255 - sizeof(struct l1sched_ts_prim) and greater.

The current function name is confusing, because l1sched_prim_init()
is not only initializing a primitive, but also allocating it on heap.
Let's use '_alloc' instead of '_init' to reflect that.

This is the first step towards the goal of moving the scheduler
