Ksplice: Add functions for walking kallsyms symbols
Impact: New API
kallsyms_lookup_name only returns the first match that it finds. Ksplice
needs information about all symbols with a given name in order to correctly
resolve local symbols.
kallsyms_on_each_symbol provides a generic mechanism for iterating over the
kallsyms table.
