5c77af98b1 Add extent serial numbers.
Add extent serial numbers and use them where appropriate as a sort key
that is higher priority than address, so that the allocation policy
prefers older extents.

This resolves #147.

1aeea0f391 Simplify extent_quantize().
2cdf07aba9 (Fix extent_quantize() to
handle greater-than-huge-size extents.) solved a non-problem; the
expression passed in to index2size() was never too large.  However the
expression could in principle underflow, so fix the actual (latent) bug
and remove unnecessary complexity.

a2af09f025 Remove overly restrictive stats_cactive_{add,sub}() assertions.

regression.) and first released in 4.1.0.

b9408d77a6 Fix/simplify chunk_recycle() allocation size computations.
Remove outer CHUNK_CEILING(s2u(...)) from alloc_size computation, since
s2u() may overflow (and return 0), and CHUNK_CEILING() is only needed
around the alignment portion of the computation.

This fixes a regression caused by
5707d6f952 (Quantize szad trees by size
class.) and first released in 4.0.0.

This resolves #497.

2cdf07aba9 Fix extent_quantize() to handle greater-than-huge-size extents.
Allocation requests can't directly create extents that exceed
HUGE_MAXCLASS, but extent merging can create them.

This fixes a regression caused by
8a03cf039c (Implement cache index
randomization for large allocations.) and first released in 4.0.0.

This resolves #497.

a4e83e8593 Fix run leak.
Fix arena_run_first_best_fit() to search all potentially non-empty
runs_avail heaps, rather than ignoring the heap that contains runs
larger than large_maxclass, but less than chunksize.

This fixes a regression caused by
f193fd80cf (Refactor runs_avail.).

This resolves #493.

28b7e42e44 Fix arena data structure size calculation.
Fix paren placement so that QUANTUM_CEILING() applies to the correct
portion of the expression that computes how much memory to base_alloc().
In practice this bug had no impact.  This was caused by
5d8db15db9 (Simplify run quantization.),
which in turn fixed an over-allocation regression caused by
3c4d92e82a (Add per size class huge
allocation statistics.).

32896a902b Fix large allocation to search optimal size class heap.
Fix arena_run_alloc_large_helper() to not convert size to usize when
searching for the first best fit via arena_run_first_best_fit().  This
allows the search to consider the optimal quantized size class, so that
e.g. allocating and deallocating 40 KiB in a tight loop can reuse the
same memory.

This regression was nominally caused by
5707d6f952 (Quantize szad trees by size
class.), but it did not commonly cause problems until
8a03cf039c (Implement cache index
randomization for large allocations.).  These regressions were first
released in 4.0.0.

This resolves #487.

e9012630ac Fix chunk_alloc_cache() to support decommitted allocation.
Fix chunk_alloc_cache() to support decommitted allocation, and use this
ability in arena_chunk_alloc_internal() and arena_stash_dirty(), so that
chunks don't get permanently stuck in a hybrid state.

This resolves #487.

a967fae362 Fix/simplify extent_recycle() allocation size computations.
Do not call s2u() during alloc_size computation, since any necessary
ceiling increase is taken care of later by extent_first_best_fit() -->
extent_size_quantize_ceil(), and the s2u() call may erroneously cause a
higher quantization result.

Remove an overly strict overflow check that was added in
4a7852137d (Fix extent_recycle()'s
cache-oblivious padding support.).

4a7852137d Fix extent_recycle()'s cache-oblivious padding support.
Add padding *after* computing the size class, so that the optimal size
class isn't skipped during search for a usable extent.  This regression
was caused by b46261d58b (Implement
cache-oblivious support for huge size classes.).

ea9961acdb Fix psz/pind edge cases.
Add an "over-size" extent heap in which to store extents which exceed
the maximum size class (plus cache-oblivious padding, if enabled).
Remove psz2ind_clamp() and use psz2ind() instead so that trying to
allocate the maximum size class can in principle succeed.  In practice,
this allows assertions to hold so that OOM errors can be successfully
generated.

8dd5ea87ca Fix extent_alloc_cache[_locked]() to support decommitted allocation.
Fix extent_alloc_cache[_locked]() to support decommitted allocation, and
use this ability in arena_stash_dirty(), so that decommitted extents are
not needlessly committed during purging.  In practice this does not
happen on any currently supported systems, because both extent merging
and decommit must be implemented; all supported systems implement one
xor the other.
