d936b46d3a Add malloc_conf_2_conf_harder
This comes in handy when you're just a user of a canary system who wants to
change settings set by the configuration system itself.

909c501b07 Cache_bin: Shouldn't know about tcache.
Instead, have it take the cache_bin_info_ts to use by pointer.  While we're
here, add a src file for the cache bin.

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).

e210ccc57e Move extent2 -> extent.
Eventually, we may fully break off the extent module; but not for some time.  If
it's going to live on in a non-transitory state, it might as well have the nicer
name.

bb70df8e5b Extent refactor: Introduce ecache module.
This will eventually completely wrap the eset, and handle concurrency,
allocation, and deallocation.  For now, we only pull out the mutex from the
eset.

865debda22 Rename extent.h -> edata.h.
This name is slightly pithier; a full-on rename will come shortly.

403f2d1664 Extents: Split out introspection functionality.
This isn't really part of the core extent allocation facilities.  Especially as
this module grows, having it in its own place may come in handy.

92a511d385 Make extent module hermetic.
In the form of extent2.h.  The naming leaves something to be desired, but I'll
leave that for a later diff.

7599c82d48 Redesign the cache bin metadata for fast path.
Implement the pointer-based metadata for tcache bins --
- 3 pointers are maintained to represent each bin;
- 2 of the pointers are compressed on 64-bit;
- is_full / is_empty done through pointer comparison;

Comparing to the previous counter based design --
- fast-path speed up ~15% in benchmarks
- direct pointer comparison and de-reference
- no need to access tcache_bin_info in common case

7fc6b1b259 Add buffered writer
The buffered writer adopts a signature identical to `write_cb`,
so that it can be plugged into anywhere `write_cb` appears.

07ce2434bf Refactor profiling
Refactored core profiling codebase into two logical parts:

(a) `prof_data.c`: core internal data structure managing & dumping;
(b) `prof.c`: mutexes & outward-facing APIs.

Some internal functions had to be exposed out, but there are not
that many of them if the modularization is (hopefully) clean enough.

56126d0d2d Refactor prof log
Prof logging is conceptually seperate from core profiling, so
split it out as a module of its own.  There are a few internal
functions that had to be exposed but I think it is a fair trade-off.

`prof.c` is growing too long, so trying to modularize it.  There are
a few internal functions that had to be exposed but I think it is a
fair trade-off.

9015deb126 Add build_doc by default.
However, skip building the docs (and output warnings) if XML support is missing.
This allows `make install` to succeed w/o `make dist`.

471191075d Replace -lpthread with -pthread
This automatically adds -latomic if and when needed, e.g. on riscv64
systems.

Fixes #1401.

4e920d2c9d Add --{enable,disable}-{static,shared} to configure script
My distro offers a custom toolchain where it's not possible to make
static libs, so it's insufficient to just delete the libs I don't want.
I actually need to avoid building them in the first place.

e904f813b4 Hide size class computation behind a layer of indirection.
This class removes almost all the dependencies on size_classes.h, accessing the
data there only via the new module sc.h, which does not depend on any
configuration options.

In a subsequent commit, we'll remove the configure-time size class computations,
doing them at boot time, instead.

5ae6e7cbfa Add "hook" module.
The hook module allows a low-reader-overhead way of finding hooks to invoke and
calling them.

For now, none of the allocation pathways are tied into the hooks; this will come
later.
