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.

Stop depending on JEMALLOC_N() for function interception during testing. Instead, always define function pointers for interceptable functions, but mark them const unless testing, so that the compiler can optimize out the pointer dereferences.

Make dss operations lockless. Rather than protecting dss operations with a mutex, use atomic operations. This has negligible impact on synchronization overhead during typical dss allocation, but is a substantial improvement for extent_in_dss() and the newly added extent_dss_mergeable(), which can be called multiple times during extent deallocations. This change also has the advantage of avoiding tsd in deallocation paths associated with purging, which resolves potential deadlocks during thread exit due to attempted tsd resurrection. This resolves #425.
