*	Replace JEMALLOC_OPTIONS with MALLOC_CONF.	Jason Evans	2010-10-24	1	-10/+10
\| \| \| \| \| \| \| \| \| \| \|	Replace the single-character run-time flags with key/value pairs, which can be set via the malloc_conf global, /etc/malloc.conf, and the MALLOC_CONF environment variable. Replace the JEMALLOC_PROF_PREFIX environment variable with the "opt.prof_prefix" option. Replace umax2s() with u2s().
*	Add per thread allocation counters, and enhance heap sampling.	Jason Evans	2010-10-21	2	-0/+107
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Add the "thread.allocated" and "thread.deallocated" mallctls, which can be used to query the total number of bytes ever allocated/deallocated by the calling thread. Add s2u() and sa2u(), which can be used to compute the usable size that will result from an allocation request of a particular size/alignment. Re-factor ipalloc() to use sa2u(). Enhance the heap profiler to trigger samples based on usable size, rather than request size. This has a subtle, but important, impact on the accuracy of heap sampling. For example, previous to this change, 16- and 17-byte objects were sampled at nearly the same rate, but 17-byte objects actually consume 32 bytes each. Therefore it was possible for the sample to be somewhat skewed compared to actual memory usage of the allocated objects.
*	Fix tests build when --with-install-suffix is set.	Jason Evans	2010-10-07	5	-4/+10
\| \| \| \| \| \|	Add test/jemalloc_test.h.in, which is processed to include jemalloc/jemalloc@install_suffix@.h, so that test programs can include it without worrying about the install suffix.
*	Fix compiler warnings.	Jason Evans	2010-09-21	1	-2/+13
\| \| \| \| \| \|	Add --enable-cc-silence, which can be used to silence harmless warnings. Fix an aliasing bug in ckh_pointer_hash().
*	Add {,r,s,d}allocm().	Jason Evans	2010-09-17	5	-3/+279
\| \| \| \| \| \|	Add allocm(), rallocm(), sallocm(), and dallocm(), which are a functional superset of malloc(), calloc(), posix_memalign(), malloc_usable_size(), and free().
*	Fix porting regressions.	Jason Evans	2010-09-12	2	-13/+7
\| \| \| \| \|	Fix new build failures and test failures on Linux that were introduced by the port to OS X.
*	Add posix_memalign test.	Jason Evans	2010-09-12	2	-0/+153
\|
*	Port to Mac OS X.	Jason Evans	2010-09-12	1	-4/+6
\| \| \| \| \|	Add Mac OS X support, based in large part on the OS X support in Mozilla's version of jemalloc.
*	Add the thread.arena mallctl.	Jason Evans	2010-08-14	2	-0/+71
	Make it possible for each thread to manage which arena it is associated with. Implement the 'tests' and 'check' build targets.
