c86c8f4ffb Add extent_destroy_t and use it during arena destruction.
Add the extent_destroy_t extent destruction hook to extent_hooks_t, and
use it during arena destruction.  This hook explicitly communicates to
the callee that the extent must be destroyed or tracked for later reuse,
lest it be permanently leaked.  Prior to this change, retained extents
could unintentionally be leaked if extent retention was enabled.

This resolves #560.

743d940dc3 Header refactoring: Split up jemalloc_internal.h
This is a biggy.  jemalloc_internal.h has been doing multiple jobs for a while
now:
- The source of system-wide definitions.
- The catch-all include file.
- The module header file for jemalloc.c

This commit splits up this functionality.  The system-wide definitions
responsibility has moved to jemalloc_preamble.h.  The catch-all include file is
now jemalloc_internal_includes.h.  The module headers for jemalloc.c are now in
jemalloc_internal_[externs|inlines|types].h, just as they are for the other
modules.

0a0fcd3e6a Add hooking functionality

e9852b5776 Disentangle assert and util
This is the first header refactoring diff, #533.  It splits the assert and util
components into separate, hermetic, header files.  In the process, it splits out
two of the large sub-components of util (the stdio.h replacement, and bit
manipulation routines) into their own components (malloc_io.h and bit_util.h).
This is mostly to break up cyclic dependencies, but it also breaks off a good
chunk of the catch-all-ness of util, which is nice.

77cccac8cd Break up headers into constituent parts
This is part of a broader change to make header files better represent the
dependencies between one another (see
https://github.com/jemalloc/jemalloc/issues/533). It breaks up component headers
into smaller parts that can be made to have a simpler dependency graph.

For the autogenerated headers (smoothstep.h and size_classes.h), no splitting
was necessary, so I didn't add support to emit multiple headers.

3f291d59ad Refactor test extent hook code to be reusable.
Move test extent hook code from the extent integration test into a
header, and normalize the out-of-band controls and introspection.
Also refactor the base unit test to use the header.

2319152d9f jemalloc cpp new/delete bindings
Adds cpp bindings for jemalloc, along with necessary autoconf settings.
This is mostly to add sized deallocation support, which can't be added
from C directly.  Sized deallocation is ~10% microbench improvement.

* Import ax_cxx_compile_stdcxx.m4 from the autoconf repo, seems like the
  easiest way to get c++14 detection.
* Adds various other changes, like CXXFLAGS, to configure.ac.
* Adds new rules to Makefile.in for src/jemalloc-cpp.cpp, and a basic
  unittest.
* Both new and delete are overridden, to ensure jemalloc is used for
  both.
* TODO future enhancement of avoiding extra PLT thunks for new and
  delete - sdallocx and malloc are publicly exported jemalloc symbols,
  using an alias would link them directly.  Unfortunately, was having
  trouble getting it to play nice with jemalloc's namespace support.

Testing:
Tested gcc 4.8, gcc 5, gcc 5.2, clang 4.0.  Only gcc >= 5 has sized
deallocation support, verified that the rest build correctly.

Tested mac osx and Centos.

Tested --with-jemalloc-prefix and --without-export.

This resolves #202.

ff63dca363 Avoid blindly enabling assertions for header code when testing.
Restructure the test program master header to avoid blindly enabling
assertions.  Prior to this change, assertion code in e.g. arena.h was
always enabled for tests, which could skew performance-related testing.

9bad079039 Refactor time_* into nstime_*.
Use a single uint64_t in nstime_t to store nanoseconds rather than using
struct timespec.  This reduces fragility around conversions between long
and uint64_t, especially missing casts that only cause problems on
32-bit platforms.

5fae7dc1b3 Fix MinGW-related portability issues.
Create and use FMT* macros that are equivalent to the PRI* macros that
inttypes.h defines.  This allows uniform use of the Unix-specific format
specifiers, e.g. "%zu", as well as avoiding Windows-specific definitions
of e.g. PRIu64.

Add ffs()/ffsl() support for compiling with gcc.

Extract compatibility definitions of ENOENT, EINVAL, EAGAIN, EPERM,
ENOMEM, and ENORANGE into include/msvc_compat/windows_extra.h and
use the file for tests as well as for core jemalloc code.

profiling was enabled.

d6384b09e1 use CLOCK_MONOTONIC in the timer if it's available
Linux sets _POSIX_MONOTONIC_CLOCK to 0 meaning it *might* be available,

e3f27cfced Fix p_test_fail()'s va_list abuse.
p_test_fail() was passing a va_list to two separate functions with the
expectation that no reset would occur.  Refactor p_test_fail()'s callers
to instead format two strings and pass them to p_test_fail().

warned about after the assertion macro refactoring.

f234dc51b9 Fix name mangling for stress tests.
Fix stress tests such that testlib code uses the jet_ allocator, but
test code uses libjemalloc.

Generate jemalloc_{rename,mangle}.h, the former because it's needed for
the stress test name mangling fix, and the latter for consistency.  As
an artifact of this change, some (but not all) definitions related to
the experimental API are absent from the headers unless the feature is
enabled at configure time.

e18c25d23d Add util unit tests, and fix discovered bugs.
Add unit tests for pow2_ceil(), malloc_strtoumax(), and
malloc_snprintf().

Fix numerous bugs in malloc_strotumax() error handling/reporting.  These
bugs could have caused application-visible issues for some seldom used
(0X... and 0... prefixes) or malformed MALLOC_CONF or mallctl() argument
strings, but otherwise they had no impact.

Fix numerous bugs in malloc_snprintf().  These bugs were not exercised
by existing malloc_*printf() calls, so they had no impact.

In this case the replaced function is ordinarily a static function, but
the idiom should work similarly for library-private functions.

Move je_* definitions from jemalloc_macros.h.in to jemalloc_defs.h.in,

macro-substituted to becom jet_mallocx.

Remove SFMT's inline-related macros and use jemalloc's instead, so that
there's no danger of interactions with jemalloc's definitions that
disable inlining for debug builds.

Add probabability distribution utility code that enables generation of
random deviates drawn from normal, Chi-square, and Gamma distributions.

Fix format strings in several of the assert_* macros (remove a %s).

Clean up header issues; it's critical that system headers are not
included after internal definitions potentially do things like:

  #define inline

Fix the build system to incorporate header dependencies for the test
library C files.

The sfmt_t state encapsulation modification comes from Crux
(http://www.canonware.com/Crux/) and enables multiple
concurrent PRNGs.

86abd0dcd8 Refactor to support more varied testing.
Refactor the test harness to support three types of tests:
- unit: White box unit tests.  These tests have full access to all
  internal jemalloc library symbols.  Though in actuality all symbols
  are prefixed by jet_, macro-based name mangling abstracts this away
  from test code.
- integration: Black box integration tests.  These tests link with
  the installable shared jemalloc library, and with the exception of
  some utility code and configure-generated macro definitions, they have
  no access to jemalloc internals.
- stress: Black box stress tests.  These tests link with the installable
  shared jemalloc library, as well as with an internal allocator with
  symbols prefixed by jet_ (same as for unit tests) that can be used to
  allocate data structures that are internal to the test code.

Move existing tests into test/{unit,integration}/ as appropriate.

Split out internal parts of jemalloc_defs.h.in and put them in
jemalloc_internal_defs.h.in.  This reduces internals exposure to
applications that #include <jemalloc/jemalloc.h>.

Refactor jemalloc.h header generation so that a single header file
results, and the prototypes can be used to generate jet_ prototypes for
tests.  Split jemalloc.h.in into multiple parts (jemalloc_defs.h.in,
jemalloc_macros.h.in, jemalloc_protos.h.in, jemalloc_mangle.h.in) and
use a shell script to generate a unified jemalloc.h at configure time.

Change the default private namespace prefix from "" to "je_".

Add missing private namespace mangling.

Remove hard-coded private_namespace.h.  Instead generate it and
private_unnamespace.h from private_symbols.txt.  Use similar logic for
public symbols, which aids in name mangling for jet_ symbols.

Add test_warn() and test_fail().  Replace existing exit(1) calls with
test_fail() calls.
