5bee66d3ed Add variables for library prefix, and static library, object and executable suffixes
This makes hacking on Makefile easier.

6f2ed70f5a Use $(LIBS) instead of -lpthread when linking tests
This will allow linking for win32 without pthreads more easily

f5e0f526ec Remove -dynamic CFLAG on OSX
It is a linker flag, so it doesn't make sense in CFLAGS, and it's the
default when invoking the linker for shared libraries.

927893b478 Remove bogus dependency
test/bitmap.c #includes src/bitmap.c, which is correctly detected by gcc -MM,
but building test/bitmap.o doesn't require src/bitmap.o.

122449b073 Implement Valgrind support, redzones, and quarantine.
Implement Valgrind support, as well as the redzone and quarantine
features, which help Valgrind detect memory errors.  Redzones are only
implemented for small objects because the changes necessary to support
redzones around large and huge objects are complicated by in-place
reallocation, to the point that it isn't clear that the maintenance
burden is worth the incremental improvement to Valgrind support.

Merge arena_salloc() and arena_salloc_demote().

Refactor i[v]salloc() to expose the 'demote' option.

a8683fbaf9 Ignore whitespaces when comparing test results with expected output
In mingw, the test result may contain CRLF while the .exp files don't, or
the other way around.

f004737267 Revert "Avoid NULL check in free() and malloc_usable_size()."
This reverts commit 96d4120ac0.

ivsalloc() depends on chunks_rtree being initialized.  This can be
worked around via a NULL pointer check.  However,
thread_allocated_tsd_get() also depends on initialization having
occurred, and there is no way to guard its call in free() that is
cheaper than checking whether ptr is NULL.

96d4120ac0 Avoid NULL check in free() and malloc_usable_size().
Generalize isalloc() to handle NULL pointers in such a way that the NULL
checking overhead is only paid when introspecting huge allocations (or
NULL).  This allows free() and malloc_usable_size() to no longer check
for NULL.

Submitted by Igor Bukanov and Mike Hommey.

cd9a1346e9 Implement tsd.
Implement tsd, which is a TLS/TSD abstraction that uses one or both
internally.  Modify bootstrapping such that no tsd's are utilized until
allocation is safe.

Remove malloc_[v]tprintf(), and use malloc_snprintf() instead.

Fix %p argument size handling in malloc_vsnprintf().

Fix a long-standing statistics-related bug in the "thread.arena"
mallctl that could cause crashes due to linked list corruption.

0a0bbf63e5 Implement aligned_alloc().
Implement aligned_alloc(), which was added in the C11 standard.  The
function is weakly specified to the point that a minimally compliant
implementation would be painful to use (size must be an integral
multiple of alignment!), which in practice makes posix_memalign() a
safer choice.

d81e4bdd5c Implement malloc_vsnprintf().
Implement malloc_vsnprintf() (a subset of vsnprintf(3)) as well as
several other printing functions based on it, so that formatted printing
can be relied upon without concern for inducing a dependency on floating
point runtime support.  Replace malloc_write() calls with
malloc_*printf() where doing so simplifies the code.

Add name mangling for library-private symbols in the data and BSS
sections.  Adjust CONF_HANDLE_*() macros in malloc_conf_init() to expose
all opt_* variable use to cpp so that proper mangling occurs.

4162627757 Remove the swap feature.
Remove the swap feature, which enabled per application swap files.  In
practice this feature has not proven itself useful to users.

f576c63f1e Refactor SO and REV make variables.
Refactor the SO and REV such that they are set via autoconf variables,
@so@ and @rev@.  These variables are both needed by the jemalloc.sh
script, so this unifies their definitions.
