[lib] hash compare function arguments ought to be const qualified
2008-08-14 Stephen Hemminger <stephen.hemminger@vyatta.com>
* lib/hash.h: (struct hash) Hash comparator callback really
ought to treat storage behind arguments as constant - a compare
function with side-effects would be evil.
* */*.c: Adjust comparator functions similarly, thus fixing at least
a few compiler warnings about const qualifier being dropped.
