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.

Change opt.metadata_thp to [disabled,auto,always]. 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.

extern const char *metadata_thp_mode_names[];
Implement opt.metadata_thp This option enables transparent huge page for base allocators (require MADV_HUGEPAGE support).

Track extent structure serial number (esn) in extent_t. This enables stable sorting of extent_t structures.

Set reentrancy when invoking customized extent hooks. Customized extent hooks may malloc / free thus trigger reentry. Support this behavior by adding reentrancy on hook functions.
