eal: rename IPC request as synchronous one

Rename rte_mp_request to rte_mp_request_sync to indicate
that this request will be done synchronously (as opposed to
asynchronous request, which comes in next patch).

Also, fix alphabetical ordering for .map file.

eal: rename IPC sync request to pending request

Originally, there was only one type of request which was used
for multiprocess synchronization (hence the name - sync request).

However, now that we are going to have two types of requests,
synchronous and asynchronous, having it named "sync request" is
very confusing, so we will rename it to "pending request". This
is internal-only, so no externally visible API changes.

eal: support strlcpy function

The strncpy function is error prone for doing "safe" string copies, so
we generally try to use "snprintf" instead in the code. The function
"strlcpy" is a better alternative, since it better conveys the
intention of the programmer, and doesn't suffer from the non-null
terminating behaviour of it's n'ed brethern.

The downside of this function is that it is not available by default
on linux, though standard in the BSD's. It is available on most
distros by installing "libbsd" package.

This patch therefore provides the following in rte_string_fns.h to ensure
that strlcpy is available there:
* for BSD, include string.h as normal
* if RTE_USE_LIBBSD is set, include <bsd/string.h>
* if not set, fallback to snprintf for strlcpy

Using make build system, the RTE_USE_LIBBSD is a hard-coded value to "n",
but when using meson, it's automatically set based on what is available
on the platform.

eal: register log type and pick level from args

Dynamic log types are registered on RTE_INIT() step.
This allows one to set log levels by EAL options on
application launch. However, this does not allow to
manage log types if they are created during runtime.

EAL does not store log levels and types passed from

This is an obvious flaw since it would be better to

net/mlx5: fix link status behavior

This behavior is mixed between what should be handled by the application
and what is under PMD responsibility.

According to DPDK API:
- link_update() should only query the link status [1]
- link_set_{up,down}() should only set the link to the according status [1]
- dev_{start,stop}() should enable/disable traffic reception/emission [2]

On this PMD, the link status is retrieved from the net device associated
owned by the Linux Kernel, it does not means that even when this interface
is down, the PMD cannot send/receive traffic from the NIC those two
information are unrelated, until the physical port is active and has a
link, the PMD can receive/send traffic on the wire.

According to DPDK API, calling the rte_eth_dev_start() even when the Linux
interface link is down is then possible and allowed, as the traffic will
flow between the DPDK application and the Physical port.

This also means that a synchronization between the Linux interface and the
DPDK application remains under the DPDK application responsibility.

To handle such synchronization the application should behave as the
following scheme, to start:

 rte_eth_get_link(port_id, &link);
 if (link.link_status == ETH_DOWN)
rte_eth_dev_set_link_up(port_id);
 rte_eth_dev_start(port_id);

Taking in account the possible returned values for each function.

and to stop:

 rte_eth_dev_stop(port_id);
 rte_eth_dev_set_link_down(port_id);

The application should also set the LSC interrupt callbacks to catch and
behave accordingly when the administrator set the Linux device down/up.
The same callbacks are called when the link on the medium falls/raise.
