examples/multi_process: fix Rx packets distribution

MP servers distributes Rx packets between clients according to
round-robin scheme.

Current implementation always started packets distribution from
the first client. That procedure resulted in uniform distribution
in cases when Rx packets number was around clients number
multiplication. However, if RX burst repeatedly returned single
packet, round-robin scheme would not work because all packets
were assigned to the first client only.

The patch does not restart packets distribution from
the first client.
Packets distribution always continues to the next client.

examples/multi_process: fix build on Ubuntu 20.04

Two warnings are reported by gcc 9.3.0 on Ubuntu 20.04.

When producing a printable mac address the buffer was appropriately sized
for holding the mac address exactly, but the actual snprintf included a
'\n' character at the end, which means that the snprintf technically is
getting truncated i.e. the \n would not be added due to lack of space.
This gets flagged as a problem by modern versions of gcc, e.g. on Ubuntu
20.04.

main.c:77:37: warning: ‘__builtin___snprintf_chk’ output truncated
before the last format character [-Wformat-truncation=]
77 | "%02x:%02x:%02x:%02x:%02x:%02x\n",
| ^

Since the \n is getting stripped anyway, we can fix the issue by just
removing it. In the process we can switch to using the standard ethernet
address formatting function from rte_ether.h.

The other warning is about possible string truncation when getting the
RX queue name:

In file included from init.c:36:
init.c: In function ‘init’:
../shared/common.h:38:28: warning: ‘%u’ directive output may be truncated
writing between 1 and 10 bytes into a region of size 8
[-Wformat-truncation=]
38 | #define MP_CLIENT_RXQ_NAME "MProc_Client_%u_RX"
| ^~~~~~~~~~~~~~~~~~~~
../shared/common.h:52:35: note: in expansion of macro ‘MP_CLIENT_RXQ_NAME’
52 | snprintf(buffer, sizeof(buffer), MP_CLIENT_RXQ_NAME, id);
| ^~~~~~~~~~~~~~~~~~

This is a false positive, as the value of the "id" is limited to 255,
being stored in the app as a uint8_t value, removing the possibility of
the %u being replaced by anything other then 3 characters max (rather than
up to 10 as thought by the compiler). Therefore, the warning can be easily
removed by changing the type of the "id" parameter to the local function
from "unsigned" to "uint8_t" also, ensuring the compiler is aware of the
range limit.

ring: return free space when enqueuing

Add an extra parameter to the ring enqueue burst/bulk functions so that
those functions can optionally return the amount of free space in the
ring. This information can be used by applications in a number of ways,
for instance, with single-producer queues, it provides a max
enqueue size which is guaranteed to work. It can also be used to
implement watermark functionality in apps, replacing the older
functionality with a more flexible version, which enables apps to
implement multiple watermark thresholds, rather than just one.
