Header refactoring: Split up jemalloc_internal.h This is a biggy. jemalloc_internal.h has been doing multiple jobs for a while now: - The source of system-wide definitions. - The catch-all include file. - The module header file for jemalloc.c This commit splits up this functionality. The system-wide definitions responsibility has moved to jemalloc_preamble.h. The catch-all include file is now jemalloc_internal_includes.h. The module headers for jemalloc.c are now in jemalloc_internal_[externs|inlines|types].h, just as they are for the other modules.

Enable -Wundef, when supported. This can catch bugs in which one header defines a numeric constant, and another uses it without including the defining header. Undefined preprocessor symbols expand to '0', so that this will compile fine, silently doing the math wrong.

*/
Automatically generate private symbol name mangling macros. Rather than using a manually maintained list of internal symbols to drive name mangling, add a compilation phase to automatically extract the list of internal symbols. This resolves #677.

Remove --enable-ivsalloc. Continue to use ivsalloc() when --enable-debug is specified (and add assertions to guard against 0 size), but stop providing a documented explicit semantics-changing band-aid to dodge undefined behavior in sallocx() and malloc_usable_size(). ivsalloc() remains compiled in, unlike when #211 restored --enable-ivsalloc, and if JEMALLOC_FORCE_IVSALLOC is defined during compilation, sallocx() and malloc_usable_size() will still use ivsalloc(). This partially resolves #580.

Implementing opt.background_thread. Added opt.background_thread to enable background threads, which handles purging currently. When enabled, decay ticks will not trigger purging (which will be left to the background threads). We limit the max number of threads to NCPUs. When percpu arena is enabled, set CPU affinity for the background threads as well. The sleep interval of background threads is dynamic and determined by computing number of pages to purge in the future (based on backlog).
