Subject: Adapt Carpet to hierarchical timers

Specifically, remove any hierarchy information that has been added to
the name of timers, as well as any code for creating timers
dynamically, as these are now unnecessary.  Additionally, time some
previously-untimed parts of the code and make timer names in some
places more consistent.
