*	Add stats for metadata_thp.	Qi Wang	2017-08-30	1	-1/+1
\| \| \| \|	Report number of THPs used in arena and aggregated stats.
*	Change opt.metadata_thp to [disabled,auto,always].	Qi Wang	2017-08-30	1	-1/+2
\| \| \| \| \| \| \| \|	To avoid the high RSS caused by THP + low usage arena (i.e. THP becomes a significant percentage), added a new "auto" option which will only start using THP after a base allocator used up the first THP region. Starting from the second hugepage (in a single arena), "auto" behaves the same as "always", i.e. madvise hugepage right away.
*	Implement opt.metadata_thp	Qi Wang	2017-08-11	1	-0/+2
\| \| \| \| \|	This option enables transparent huge page for base allocators (require MADV_HUGEPAGE support).
*	Set reentrancy when invoking customized extent hooks.	Qi Wang	2017-06-23	1	-1/+1
\| \| \| \| \|	Customized extent hooks may malloc / free thus trigger reentry. Support this behavior by adding reentrancy on hook functions.
*	Track extent structure serial number (esn) in extent_t.	Jason Evans	2017-04-17	1	-11/+12
\| \| \| \|	This enables stable sorting of extent_t structures.
*	Break up headers into constituent parts	David Goldblatt	2017-01-12	1	-0/+18
	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.
