[PATCH v4 0/4] tools: ynl: add install target

[Jan Stancek <jstancek@redhat.com>]

This series adds an install target for ynl. The python code
is moved to a subdirectory, so it can be used as a package
with flat layout, as well as directly from the tree.

To try the install as a non-root user you can run:
  $ mkdir /tmp/myroot
  $ make DESTDIR=/tmp/myroot install

  $ PATH="/tmp/myroot/usr/bin:$PATH" PYTHONPATH="$(ls -1d /tmp/myroot/usr/lib/python*/site-packages)" ynl --help

Proposed install layout is described in last patch.

Changes in v4:
- 1/4 tools: ynl: move python code to separate sub-directory
  no code changes, added Reviewed-by tag from v3
- 2/4 tools: ynl: add initial pyproject.toml for packaging
  no longer installs ynl-gen-c and ynl-gen-rst
  updated commit message
- 3/4 tools: ynl: add install target for generated content
  fixed mix of tabs and spaces in Makefile
  factored out SPECS_DIR so the path is not repeated
  fixed TOOL2->TOOL_RST
  moved clear of .rst to distclean
- 4/4 tools: ynl: add main install target
  no code changes, added Reviewed-by tags from v3

Changes in v3:
- dropped symlinks
- added install-headers install-rsts install-specs to PHONY target in generated/Makefile
- install headers from lib and generated directories to /usr/include/ynl

Changes in v2:
- squashed 1st and 2nd patch together
- added symlinks for original user-facing scripts for backwards compatibility
- updated also Documentation and selftests references
  (tested Doc build and selftests ping.py test)
