[RFC]: net-sched 00/05: dynamically sized class hashes

[Patrick McHardy <kaber@trash.net>]

These patches add support for dynamically sized class hash tables
to remove a major bottleneck in qdisc filters with many classes
when filters are not bound to classes and convert CBQ, HTB and HFSC
to use them.

Only RFC at this point because they haven't been tested thoroughly yet
and depend on the filter destruction fixes I sent this morning, but any
review (especially of 4/5, the htb_delete changes) is welcome.
