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.

Clean compilation -Wextra Before this commit jemalloc produced many warnings when compiled with -Wextra with both Clang and GCC. This commit fixes the issues raised by these warnings or suppresses them if they were spurious at least for the Clang and GCC versions covered by CI. This commit: * adds `JEMALLOC_DIAGNOSTIC` macros: `JEMALLOC_DIAGNOSTIC_{PUSH,POP}` are used to modify the stack of enabled diagnostics. The `JEMALLOC_DIAGNOSTIC_IGNORE_...` macros are used to ignore a concrete diagnostic. * adds `JEMALLOC_FALLTHROUGH` macro to explicitly state that falling through `case` labels in a `switch` statement is intended * Removes all UNUSED annotations on function parameters. The warning -Wunused-parameter is now disabled globally in `jemalloc_internal_macros.h` for all translation units that include that header. It is never re-enabled since that header cannot be included by users. * locally suppresses some -Wextra diagnostics: * `-Wmissing-field-initializer` is buggy in older Clang and GCC versions, where it does not understanding that, in C, `= {0}` is a common C idiom to initialize a struct to zero * `-Wtype-bounds` is suppressed in a particular situation where a generic macro, used in multiple different places, compares an unsigned integer for smaller than zero, which is always true. * `-Walloc-larger-than-size=` diagnostics warn when an allocation function is called with a size that is too large (out-of-range). These are suppressed in the parts of the tests where `jemalloc` explicitly does this to test that the allocation functions fail properly. * adds a new CI build bot that runs the log unit test on CI. Closes #1196 .

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.

test_fail(
Refactor tests. Refactor tests to use explicit testing assertions, rather than diff'ing test output. This makes the test code a bit shorter, more explicitly encodes testing intent, and makes test failure diagnosis more straightforward.

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.

Update brace style. Add braces around single-line blocks, and remove line breaks before function-opening braces. This resolves #537.

Reduce memory requirements for regression tests. This is intended to drop memory usage to a level that AppVeyor test instances can handle. This resolves #393.
