udev: remove WAIT_FOR key This facility was never a proper solution, but only papered over real bugs in the kernel. There are no known sysfs "timing bugs" since a long time.

test: simplify rules-test.sh wrapper Drop globbing of rules/*.rules in the rules-test.sh wrapper and move that logic into the actual test rule-syntax-check.py. This can still be called with individual rules files, but when being called without arguments it will now process all top_builddir/rules/*.rules. Preparation for dropping the shell wrappers altogether.

test: Use configured Python Don't hardcode "python" or /usr/bin/python, but use the configured $(PYTHON).

test/rule-syntax-check.py: Fix for Python 3 Make this work with both Python 2 and 3.

test: add licence header and switch to LGPL Checked with and got OK from Martin.

licence: remove references to old FSF address Bug: https://bugs.freedesktop.org/show_bug.cgi?id=57206

udev: fix rule-syntax-check.py

udev: test - move test/ and src/test/

test: remove outdated key attributes

rule-syntax-check.py: use print()

Add automatic rules syntax check Add test/rule-syntax-check.py, a script for checking the syntax of all udev rules files passed as command line arguments. Add a wrapper test/rules-test.sh which calls rule-syntax-check.py on all udev rules that we ship, but does nothing if Python is not available. Integrate this into make check/distcheck.
