remove KNI

The KNI driver had design flaws such as calling userspace with kernel
mutex held that made it prone to deadlock. The design also introduced
security risks because the kernel driver trusted the userspace
(DPDK) kni interface. The kernel driver was never reviewed by
the upstream kernel community and would never have been accepted.

And since the Linux kernel API is not stable, it was a continual
source of maintenance issues especially with distribution kernels.

There are better ways to inject packets into the kernel such as
virtio_user, tap and XDP drivers. All of these do not need out of
tree kernel drivers.

The deprecation was announced in 22.11 release (see links for the
the techboard discussions); and users were directed to alternatives
there.

examples: stop processing meson file if build impossible

Once it has been determined that an example cannot be built, there is
little point in continuing to process the meson.build file for that
example, so we can use subdir_done() to return to the calling file.
This can potentially prevent problems where later statement in the file
may cause an error on systems where the app cannot be built, e.g. on
Windows or FreeBSD.

examples: build some samples with meson

Add support for having selected example apps built as part of a meson,
ninja build. By default none are built, and those to be built should be
named directly in the -Dexamples='' meson configuration argument.

This is useful for developers working on a feature who want to use a
suitable example, or examples, to test that feature, as they can compile
everything up in one go, and run the example without having to do a ninja
install first.

This commit adds examples which don't consist of multiple apps in
subdirectories to the meson build, so they can be built by default by
passing -Dexamples parameter to meson.

Not included are the following examples:
* ethtool
* multi-process
* netmap_compat
* performance-thread
* quota_watermark
* server_node_efd
* vm_power_manager

To test the apps added here, use the following command, merged to one line,
to add them to your meson build (command to be run inside the build
directory):

meson configure -Dexamples=bbdev_app,bond,cmdline,distributor,\
eventdev_pipeline_sw_pmd, exception_path,helloworld,\
ip_fragmentation,ip_pipeline,ip_reassembly, ipsec-secgw,\
ipv4_multicast,kni,l2fwd-cat,l2fwd-crypto,l2fwd-jobstats,\
l2fwd-keepalive,l2fwd,l3fwd-acl,l3fwd-power,l3fwd-vf,l3fwd,\
link_status_interrupt,load_balancer,packet_ordering,ptpclient,\
qos_meter,qos_sched,rxtx_callbacks,skeleton,tep_termination,\
timer,vhost,vhost_scsi,vmdq,vmdq_dcb
