Denis Vlasenko ba1315d0fb modutils/*: rewrite by Timo Teras <timo.teras AT iki.fi>
- a lot faster (linear algorithmic complexity, smaller memory foot print)
- a lot smaller (the old code was overly complicated)
- loading of aliases is now module-init-tools compliant
- blacklisting is done correctly (-b option added)
- module argument quoting done right
- depmod now correctly generates modules.symbols and modules.alias
