88b0e03a4e Implement opt.stats_interval and the _opts options. 
Add options stats_interval and stats_interval_opts to allow interval based stats
printing.  This provides an easy way to collect stats without code changes,
because opt.stats_print may not work (some binaries never exit).

4e36ce34c1 Track the leaked VM space via the abandoned_vm counter. 
The counter is 0 unless metadata allocation failed (indicates OOM), and is
mainly for sanity checking.

c92ac30601 Add confirm_conf option 
If the confirm_conf option is set, when the program starts, each of
the four malloc_conf strings will be printed, and each option will
be printed when being set.

07c44847c2 Track nfills and nflushes for arenas.i.small / large. 
Small is added purely for convenience.  Large flushes wasn't tracked before and
can be useful in analysis.  Large fill simply reports nmalloc, since there is no
batch fill for large currently.

7fc4f2a32c Add nonfull_slabs to bin_stats_t. 
When config_stats is enabled track the size of bin->slabs_nonfull in
the new nonfull_slabs counter in bin_stats_t. This metric should be
useful for establishing an upper ceiling on the savings possible by
meshing.

e3db480f6f Rename huge_threshold to oversize_threshold. 
The keyword huge tend to remind people of huge pages which is not relevent to
the feature.

eb261e53a6 Small refactoring of emitter 
- Make API more clear for using as standalone json emitter
- Support cases that weren't possible before, e.g.
	- emitting primitive values in an array
	- emitting nested arrays

4c36cd2cc5 Stats printing: Convert arena large stats to use emitter. 
This completes the conversion; we now have only structured text output.

a9f3cedc6e Stats printing: remove a spurious newline. 
This was left over from a previous emitter conversion.  It didn't affect the
correctness of the output.

9e1846b004 Stats printing: move non-mutex arena stats to the emitter. 
Another step in the conversion process.  The mutex is a little different,
because we we want to emit it as an array.

8076b28721 Stats printing: Remove explicit callback passing to stats_print_helper. 
This makes the emitter the only source of callback information, which is a step
towards where we want to be.

0d20eda127 Stats printing: Move emitter -> manual cutoff point. 
This makes it so that the "general" portion of the stats code is completely
agnostic to emitter type.

e4f090e8df Add opt.thp which allows explicit hugepage usage. 
"always" marks all user mappings as MADV_HUGEPAGE; while "never" marks all
mappings as MADV_NOHUGEPAGE. The default setting "default" does not change any
settings.  Note that all the madvise calls are part of the default extent hooks
by design, so that customized extent hooks have complete control over the
mappings including hugepage settings.
