8edfc5b170 Add ticker_geom_t.
This lets a single ticker object drive events across a large number of different
tick streams while sharing state.

0ec656eb71 ticker: add ticker_trytick
For the fastpath, we want to tick, but undo the tick and jump to the
slowpath if ticker would fire.

dd7e283b6f Tweak the ticker paths to help GCC generate better code.
GCC on its own isn't quite able to turn the ticker subtract into a memory
operation followed by a js.

209f2926b8 Header refactoring: tsd - cleanup and dependency breaking.
This removes the tsd macros (which are used only for tsd_t in real builds).  We
break up the circular dependencies involving tsd.

We also move all tsd access through getters and setters.  This allows us to
assert that we only touch data when tsd is in a valid state.

We simplify the usages of the x macro trick, removing all the customizability
(get/set, init, cleanup), moving the lifetime logic to tsd_init and tsd_cleanup.
This lets us make initialization order independent of order within tsd_t.

77cccac8cd Break up headers into constituent parts
This is part of a broader change to make header files better represent the
dependencies between one another (see
https://github.com/jemalloc/jemalloc/issues/533). It breaks up component headers
into smaller parts that can be made to have a simpler dependency graph.

For the autogenerated headers (smoothstep.h and size_classes.h), no splitting
was necessary, so I didn't add support to emit multiple headers.

9998000b2b Implement ticker.
Implement ticker, which provides a simple API for ticking off some
number of events before indicating that the ticker has hit its limit.
