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.

Remove --enable-code-coverage. This option hasn't been particularly useful since the original pre-3.0.0 push to broaden test coverage. This partially resolves #580.

Remove --disable-cc-silence. The explicit compiler warning suppression controlled by this option is universally desirable, so remove the ability to disable suppression. This partially resolves #580.

Add size class computation capability. Add size class computation capability, currently used only as validation of the size class lookup tables. Generalize the size class spacing used for bins, for eventual use throughout the full range of allocation sizes.

Add workaround for missing 'restrict' keyword. Add a cpp #define that removes 'restrict' keyword usage unless the compiler definitely supports C99. As written, 'restrict' is only enabled if the compiler supports the -std=gnu99 option (e.g. gcc and llvm). Reported by Tobias Hieta.

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.

/* Various function pointers are static and immutable except during testing. */
Stop depending on JEMALLOC_N() for function interception during testing. Instead, always define function pointers for interceptable functions, but mark them const unless testing, so that the compiler can optimize out the pointer dereferences.

Logging: allow logging with empty varargs. Currently, the log macro requires at least one argument after the format string, because of the way the preprocessor handles varargs macros. We can hide some of that irritation by pushing the extra arguments into a varargs function.

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 .
