74f78cafda Added custom mutex spin.
A fixed max spin count is used -- with benchmark results showing it
solves almost all problems. As the benchmark used was rather intense,
the upper bound could be a little bit high. However it should offer a
good tradeoff between spinning and blocking.

Two counters are included for the small bins: lock contention rate, and
max lock waiting time.

7f55dbef9b Enable mutex witnesses even when !isthreaded.
This fixes interactions with witness_assert_depth[_to_rank](), which was
added in d0e93ada51 (Add
witness_assert_depth[_to_rank]().).

c4c2592c83 Update brace style.
Add braces around single-line blocks, and remove line breaks before
function-opening braces.

This resolves #537.

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.
