raw/skeleton: fix selftest

ASan reported issues in this driver.

rte_rawdev_obj_t context object points at a uint16_t.
skeleton_rawdev_enqueue_bufs() and skeleton_rawdev_dequeue_bufs() were
incorrectly casting to an int.

The enqueue/dequeue selftest had a leak on the enqueued string and was
wrong in passing a rte_rawdev_buf pointer array.
Fix this by allocating buffers on the stack and check that returned
string is the expected one.

The rte_kvargs_process() was used to parse KV pairs, it also supports
to parse 'only keys' (e.g. socket_id) type. And the callback function
parameter 'value' is NULL when parsed 'only keys'.

This patch fixes segment fault when parse input args with 'only keys'
(e.g. self_test).

log: register with standardized names

Let's try to enforce the convention where most drivers use a pmd. logtype
with their class reflected in it, and libraries use a lib. logtype.

Introduce two new macros:
- RTE_LOG_REGISTER_DEFAULT can be used when a single logtype is
used in a component. It is associated to the default name provided
by the build system,
- RTE_LOG_REGISTER_SUFFIX can be used when multiple logtypes are used,
and then the passed name is appended to the default name,

RTE_LOG_REGISTER is left untouched for existing external users
and for components that do not comply with the convention.

There is a new Meson variable log_prefix to adapt the default name
for baseband (pmd.bb.), bus (no pmd.) and mempool (no pmd.) classes.

Note: achieved with below commands + reverted change on net/bonding +
edits on crypto/virtio, compress/mlx5, regex/mlx5

raw/skeleton: allow closing already closed device

This patch return OK code (0) from skeleton_rawdev_close function
if firmware is in SKELETON_FW_READY state. Formerly it returned
-EINVAL error code.

Returning an error here is troublesome as it disallows proper release
of the rawdev. The rte_rawdev_pmd_release function from librte_rawdev
library calls drivers' rawdev_close handler and continues execution
only in case of errorless call.
(see lib/librte_rawdev/rte_rawdev.c:540)

The SKELETON_FW_READY state is reached after creation, reset, unload
or close of the device. The device should be ok to be released in
such situations.

To reproduce issue fixed by this patch, call rawdev_autotest
from dpdk-test app for few times. As the device is not properly
released, the next calls will fail.
