This commit is a first attempt to isolate the udev code from the
remaining code base. It intentionally does not modify any files
but purely delete files which, on a first examination, appear to
not be needed. This is a sweeping commit which may easily have
missed needed code. Files can be retrieved by doing a checkout
from the previous commit:
git checkout 2944f347d0 -- <filename>
On systemd systems seasoned admins might be surprised to see that the
init scripts and log files are gone. To ease the transition let's place
some README files there, that hopefully help clearing up the situation.
In 29a00c41 an override was added, but commandline variables have
higher precedence than Makefile variables, so the override was not
effective for commandline variables.
While at it, duplicate for libudev.
gtk-doc add CFLAGS/LDFLAGS multiple times to the gcc command line,
which breaks options that must be listed only once.
For now, clear CFLAGS/LDFLAGS for the intermediate documentation
binary.
