243f7a0508 Implement decay-based unused dirty page purging.
This is an alternative to the existing ratio-based unused dirty page
purging, and is intended to eventually become the sole purging
mechanism.

Add mallctls:
- opt.purge
- opt.decay_time
- arena.<i>.decay
- arena.<i>.decay_time
- arenas.decay_time
- stats.arenas.<i>.decay_time

This resolves #325.

8e82af1166 Implement smoothstep table generation.
Check in a generated smootherstep table as smoothstep.h rather than
generating it at configure time, since not all systems (e.g. Windows)

f459d5a203 Detect failed profile fetches
Summary:

Currently an HTTP error response will still try to be parsed, resulting in these messages:

substr outside of string at /home/davejwatson/local/jemalloc-github/bin/jeprof line 3635, <PROFILE> line 1.
Use of uninitialized value in string eq at /home/davejwatson/local/jemalloc-github/bin/jeprof line 3635, <PROFILE> line 1.
substr outside of string at /home/davejwatson/local/jemalloc-github/bin/jeprof line 3637, <PROFILE> line 1.
Use of uninitialized value in string eq at /home/davejwatson/local/jemalloc-github/bin/jeprof line 3637, <PROFILE> line 1.
/home/davejwatson/jeprof/server.1452638936.localhost.pprof.heap: header size >= 2**16

After this fix, curl will return an error status code that will be correctly checked at line 3536, resulting in this error message:

Failed to get profile: curl -s --fail 'http://localhost:4010/pprof/heap' > /home/davejwatson/jeprof/.tmp.server.1452639085.localhost.pprof.heap: No such file or directory

Test Plan:

Tested with MALLOC_CONF="prof:false".  Also tested fetching symbols.  Didn't test redirects, but this should only affect http error codes >= 400

9cb481a73f Call malloc_test_boot0() from malloc_init_hard_recursible().
When using LinuxThreads, malloc bootstrapping deadlocks, since
malloc_tsd_boot0() ends up calling pthread_setspecific(), which causes
recursive allocation.  Fix it by moving the malloc_tsd_boot0() call to
malloc_init_hard_recursible().

The deadlock was introduced by 8bb3198f72
(Refactor/fix arenas manipulation.), when tsd_boot() was split and the
top half, tsd_boot0(), got an extra tsd_wrapper_set() call.

f4a0f32d34 Fast-path improvement: reduce # of branches and unnecessary operations.
- Combine multiple runtime branches into a single malloc_slow check.
- Avoid calling arena_choose / size2index / index2size on fast path.
- A few micro optimizations.

e8ab0ab9c0 Add function to destroy tree
ex_destroy iterates over the tree using post-order traversal so nodes
can be removed and processed by the callback function without paying the
cost to rebalance the tree. The destruction process cannot be stopped
once started.

566d4c0240 use correct macro definitions for clang-cl
clang-cl, an MSVC-compatible frontend built on top of clang, defined
_MSC_VER *and* supports __attribute__ syntax.  The ordering of the
checks in jemalloc_macros.h.in, however, do the wrong thing for
clang-cl, as we want the Windows-specific macro definitions for
clang-cl.  To support this use case, we reorder the checks so that
_MSC_VER is checked first (which includes clang-cl), and then
JEMALLOC_HAVE_ATTR) is checked.  No functionality change intended.

fed1f9f367 Fix intermittent xallocx() test failures.
Modify xallocx() tests that expect to expand in place to use a separate
arena.  This avoids the potential for interposed internal allocations
from e.g. heap profile sampling to disrupt the tests.

This resolves #286.

In addition to depending on map coalescing, the test depended on
munmap() being disabled so that chunk recycling would always succeed.
