initial commit of forward-port of libudev.so.0 code from libudev-171
minor fixes, initial built attempt works now
Removed unnecessary bits; final initial commit of legacy libudev
Make compatible with recent changes to libudev installation

Libudev now installs a different way, libudev-legacy needs to match this method.
Now, libudev.so will never be installed via libudev-lagacy; this allows changes
to src/Makefile.am to be more minimal, as well.
