v83

ndctl: release v83

This release incorporates functionality up through the 6.17 kernel.

It corrects the issue where libtracefs became a requirement to build
versions 80,81,82. Libtracefs is returned to optional status in v83.
Note that the '--media-errors' option to cxl-list, as well as the
monitor command, is not available when libtracefs is disabled.

ndctl: fix user visible spelling errors

v82

ndctl: release v82

This release incorporates functionality up through the 6.15 kernel.

Aligning with the CXL Features capability introduced in the 6.15
kernel, ndctl adds libcxl enumeration of FWCTL character devices
which enables issuing of the new ioctl's to the device.

A new CXL Features unit test is added and it includes a C program
"fwctl.c" that provides an example for users of the new capability.

Existing test and infrastructure is updated.

API:
libcxl: enumerate major/minor of FWCTL char device
libcxl: add cxl_bus_get_by_provider()
