949a27fc32 Add pthread_atfork(3) feature test.
Some versions of Android provide a pthreads library without providing
pthread_atfork(), so in practice a separate feature test is necessary
for the latter.

62f2d84e7a Refactor madvise(2) configuration.
Add feature tests for the MADV_FREE and MADV_DONTNEED flags to
madvise(2), so that MADV_FREE is detected and used for Linux kernel
versions 4.5 and newer.  Refactor pages_purge() so that on systems which
support both flags, MADV_FREE is preferred over MADV_DONTNEED.

This resolves #387.

87004d238c Avoid negation of unsigned numbers.
Rather than relying on two's complement negation for alignment mask
generation, use bitwise not and addition.  This dodges warnings from
MSVC, and should be strength-reduced by compiler optimization anyway.

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

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.

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.).
