Fixes warning with newer GCCs:

    include/jemalloc/jemalloc.h:229:2: warning: extra ';' [-Wpedantic]

This change improves interaction with transparent huge pages, e.g.
reduced page faults (at least in the absence of unused dirty page
purging).

This effectively reverts 97c04a93 (Use
first-fit rather than first-best-fit run/chunk allocation.).  In some
pathological cases, first-fit search dominates allocation time, and it
also tends not to converge as readily on a steady state of memory
layout, since precise allocation order has a bigger effect than for
first-best-fit.

Add various function attributes to the exported functions to give the
compiler more information to work with during optimization, and also
specify throw() when compiling with C++ on Linux, in order to adequately
match what __THROW does in glibc.

This resolves #237.

This {bug,regression} was introduced by
155bfa7d (Normalize size classes.).

This resolves #241.

Conditionally define ENOENT, EINVAL, etc. (was unconditional).

Add/use PRIzu, PRIzd, and PRIzx for use in malloc_printf() calls.  gcc issued
(harmless) warnings since e.g. "%zu" should be "%Iu" on Windows, and the
alternative to this workaround would have been to disable the function
attributes which cause gcc to look for type mismatches in formatted printing
function calls.

Fix typos ChangeLog

- Set opt_lg_chunk based on run-time OS setting
- Verify LG_PAGE is compatible with run-time OS setting
- When targeting Windows Vista or newer, use SRWLOCK instead of CRITICAL_SECTION
- When targeting Windows Vista or newer, statically initialize init_lock

Fix size class overflow handling for malloc(), posix_memalign(),
memalign(), calloc(), and realloc() when profiling is enabled.

Remove an assertion that erroneously caused arena_sdalloc() to fail when
profiling was enabled.

This resolves #232.

This resolves #235.

The regressions were never merged into the master branch.

This avoids the potential surprise of deallocating an object with one
tcache specified, and having the object cached in a different tcache
once it drains from the quarantine.

Now that small allocation runs have fewer regions due to run metadata
residing in chunk headers, an explicit minimum tcache count is needed to
make sure that tcache adequately amortizes synchronization overhead.

Take into account large_pad when computing whether to pass the
deallocation request to tcache_dalloc_large(), so that the largest
cacheable size makes it back to tcache.  This regression was introduced
by 8a03cf03 (Implement cache index
randomization for large allocations.).

Pass large allocation requests to arena_malloc() when possible.  This
regression was introduced by 155bfa7d
(Normalize size classes.).

This regression was introduced by

Extract szad size quantization into {extent,run}_quantize(), and .
quantize szad run sizes to the union of valid small region run sizes and
large run sizes.

Refactor iteration in arena_run_first_fit() to use
run_quantize{,_first,_next(), and add support for padded large runs.

For large allocations that have no specified alignment constraints,
compute a pseudo-random offset from the beginning of the first backing
page that is a multiple of the cache line size.  Under typical
configurations with 4-KiB pages and 64-byte cache lines this results in
a uniform distribution among 64 page boundary offsets.

Add the --disable-cache-oblivious option, primarily intended for
performance testing.

This resolves #13.

This rename avoids installation collisions with the upstream gperftools.
Additionally, jemalloc's per thread heap profile functionality
introduced an incompatible file format, so it's now worthwhile to
clearly distinguish jemalloc's version of this script from the upstream
version.

This resolves #229.

This resolves #227.

This resolves #228.
