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

The get_ib_device_match function iterates over the list of ib devices

Since this function is in use by several drivers, in this patch we
share the function in common part.

regex/mlx5: add data path scattered mbuf process

UMR (User-Mode Memory Registration) WQE can present data buffers
scattered within multiple mbufs with single indirect mkey. Take
advantage of the UMR WQE, scattered mbuf in one operation can be
presented to an indirect mkey. The RegEx which only accepts one
mkey can now process the whole scattered mbuf in one operation.

The maximum scattered mbuf can be supported in one UMR WQE is now
defined as 64. The mbufs from multiple operations can be combined
into one UMR WQE as well if there is enough space in the KLM array,
since the operations can address their own mbuf's content by the
mkey's address and length. However, one operation's scattered mbuf's
can't be placed in two different UMR WQE's KLM array, if the UMR
WQE's KLM does not has enough free space for one operation, the
extra UMR WQE will be engaged.

In case the UMR WQE's indirect mkey will be over wrapped by the SQ's
WQE move, the mkey's index used by the UMR WQE should be the index
of last the RegEX WQE in the operations. As one operation consumes
one WQE set, build the RegEx WQE by reverse helps address the mkey
more efficiently. Once the operations in one burst consumes multiple
mkeys, when the mkey KLM array is full, the reverse WQE set index
will always be the last of the new mkey's for the new UMR WQE.

In GGA mode, the SQ WQE's memory layout becomes UMR/NOP and RegEx
WQE by interleave. The UMR and RegEx WQE can be called as WQE set.
The SQ's pi and ci will also be increased as WQE set not as WQE.

For operations don't have scattered mbuf, uses the mbuf's mkey directly,
the WQE set combination is NOP + RegEx.
For operations have scattered mbuf but share the UMR WQE with others,
the WQE set combination is NOP + RegEx.
For operations complete the UMR WQE, the WQE set combination is UMR +
RegEx.

regex/mlx5: support timestamp format

This patch adds support for the timestamp format settings for
the receive and send queues. If the firmware version x.30.1000
or above is installed and the NIC timestamps are configured
with the real-time format, the default zero values for newly
added fields cause the queue creation to fail.

The patch queries the timestamp formats supported by the hardware
and sets the configuration values in queue context accordingly.

regex/mlx5: support combined rule file

The rof file holds programming instructions for
a given HW version.
In order to support future generation of HW it
was decided that the rof file will hold number
of rule configurations, and the driver will use
the one that matches the HW version.

In current code we force sync after each write block.
This has impact on performance.

The solution is to move the sync to the end of the
entire programming sequence.

regex/mlx5: fix crash on probe failure

The mlx5_regex_pci_probe function allocates a mlx5_regex_priv structure
using rte_zmalloc.

If the allocation fails, the function jumps to the dev_error label in
order to release previously allocated resources in the function.
However, in the dev_error label it attempts to refer to the internal
fields of the priv structure and if its allocation fails (as in this
case) it is actually dereferencing to NULL.

Replace the jump with an error label.

To avoid memcpy on the datapath, use dynamic memory registration.

This change will reduce latency when sending regex jobs. The first few

following mbufs will arrive from the same mempool/hugepage, there will
be no further memory registration.
