Edward Tomasz Napierala ae34b6ff96 Add four new RCTL resources - readbps, readiops, writebps and writeiops, 
for limiting disk (actually filesystem) IO.

Note that in some cases these limits are not quite precise. It's ok,
as long as it's within some reasonable bounds.

Testing - and review of the code, in particular the VFS and VM parts - is
very welcome.
