Add missing header includes in jemalloc/jemalloc.h . Add stdlib.h, stdbool.h, and stdint.h to jemalloc/jemalloc.h so that applications only have to #include <jemalloc/jemalloc.h>. This resolves #132.

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.

#define MALLOCX_ZERO ((int)0x40)
Implement explicit tcache support. Add the MALLOCX_TCACHE() and MALLOCX_TCACHE_NONE macros, which can be used in conjunction with the *allocx() API. Add the tcache.create, tcache.flush, and tcache.destroy mallctls. This resolves #145.

#define MALLOCX_ARENA(a) ((((int)(a))+1) << 20)
Implement the *allocx() API. Implement the *allocx() API, which is a successor to the *allocm() API. The *allocx() functions are slightly simpler to use because they have fewer parameters, they directly return the results of primary interest, and mallocx()/rallocx() avoid the strict aliasing pitfall that allocm()/rallocx() share with posix_memalign(). The following code violates strict aliasing rules: foo_t *foo; allocm((void **)&foo, NULL, 42, 0); whereas the following is safe: foo_t *foo; void *p; allocm(&p, NULL, 42, 0); foo = (foo_t *)p; mallocx() does not have this problem: foo_t *foo = (foo_t *)mallocx(42, 0);

Add MALLCTL_ARENAS_ALL. Add the MALLCTL_ARENAS_ALL cpp macro as a fixed index for use in accessing the arena.<i>.{purge,decay,dss} and stats.arenas.<i>.* mallctls, and deprecate access via the arenas.narenas index (to be removed in 6.0.0).

Add -Wimplicit-fallthrough checks if supported Clang since r369414 (clang-10) can now check -Wimplicit-fallthrough for C code, and use the GNU C style attribute to denote fallthrough. Move the test from header only to autoconf. The previous test used brittle version detection which did not work for newer clang that supported this feature. The attribute has to be its own statement, hence the added `;`. It also can only precede case statements, so the final cases should be explicitly terminated with break statements.
