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.

ebe0b5f828 Emitter: Add support for row-based output in table mode.
This is needed for things like mutex stats in table mode.

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.

27a8fe6780 Introduce the emitter module.
The emitter can be used to produce structured json or tabular output.  For now
it has no uses; in subsequent commits, I'll begin transitioning stats printing
code over.

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.

6b35366ef5 Skip test_alignment_and_size if percpu_arena is enabled.
test_alignment_and_size needs a lot of memory.  When percpu_arena is enabled,
multiple arenas may cause the test to OOM.

26b1c13982 Background threads: fix an indexing bug.
We have a buffer overrun that manifests in the case where arena indices higher
than the number of CPUs are accessed before arena indices lower than the number
of CPUs.  This fixes the bug and adds a test.

dd7e283b6f Tweak the ticker paths to help GCC generate better code.
GCC on its own isn't quite able to turn the ticker subtract into a memory
operation followed by a js.

f78d4ca3fb Modify configure to determine return value of strerror_r.
On glibc and Android's bionic, strerror_r returns char* when
_GNU_SOURCE is defined.

Add a configure check for this rather than assume glibc is the
only libc that behaves this way.

ba5992fe9a Improve the fit for aligned allocation.
We compute the max size required to satisfy an alignment.  However this can be
quite pessimistic, especially with frequent reuse (and combined with state-based
fragmentation).  This commit adds one more fit step specific to aligned
allocations, searching in all potential fit size classes.

78a87e4a80 Make sure JE_CXXFLAGS_ADD uses CPP compiler
All the invocations of AC_COMPILE_IFELSE inside JE_CXXFLAGS_ADD were
running 'the compiler and compilation flags of the current language'
which was always the C compiler and the CXXFLAGS were never being tested
against a C++ compiler. This patch fixes this issue by temporarily
changing the chosen compiler to C++ by pushing it over the stack and
popping it immediately after the compilation check.

7f1b02e3fa Split up and standardize naming of stats code.
The arena-associated stats are now all prefixed with arena_stats_, and live in
their own file.  Likewise, malloc_bin_stats_t -> bin_stats_t, also in its own
file.

diffs continuing this separation.

740bdd68b1 Over purge by 1 extent always.
When purging, large allocations are usually the ones that cross the npages_limit
threshold, simply because they are "large".  This means we often leave the large
extent around for a while, which has the downsides of: 1) high RSS and 2) more
chance of them getting fragmented.  Given that they are not likely to be reused
very soon (LRU), let's over purge by 1 extent (which is often large and not
reused frequently).

749caf14ae Also use __riscv to detect builds for RISC-V CPUs.
According to the RISC-V toolchain conventions, __riscv__ is the old
spelling of this definition. __riscv should be used going forward.
