[PATCH v1 0/3] Import Kernel uAPI header files

[Maxime Coquelin <maxime.coquelin@redhat.com>]

This series enables importing Linux Kernel uAPI headers
into the DPDK repository. It aims at solving alignment
issues between the build system and the system applications
linked ot DPDK libraries are run on.

It can also help simplify spaghetti code done to support
different versions of the Linux Kernel headers used by
the build system.

Guidelines and import script are also part of first patch.
The uAPI checker script has been merged with the import
script in this V1, goals is to use it in CI for any patch
touching linux-headers/uapi.

Follow-up patches are an example of imported uAPI inclusion
of VDUSE header into the Vhost library.

Changes in v1:
==============
- Merged import-linux-uapi.sh and check_linux-uapi.sh in a single linux-uapi.sh script (David)
- Moved  imported headers to kernel/linux/ (Thomas)
- Lots of fixes and improvements in the script (David)
- Fixed headers fixup to mimic linux kernel headers install (David)
- Updated documentation

Changes in RFC v3:
==================
- Support nested headers include
- Interactive mode to select which headers to include
- Store version in a file instead of git commit messages
- All imported headers aligned on same version
- Improve loops in scripts (David)
- Update documentation


Changes in RFC v2:
==================
- Fix typos in documentation and commit messags (David, Morten)
- Add uAPI checker script
- Add uAPI to global_inc
- Fix build issues on FreeBSD and documentation (CI, David)
- Simplify import script (David)

Maxime Coquelin (3):
  uapi: introduce kernel uAPI headers import
  uapi: import VDUSE header
  vduse: use imported VDUSE uAPI header
