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.

Rename hooks module to test_hooks. "Hooks" is really the best name for the module that will contain the publicly exposed hooks. So lets rename the current "hooks" module (that hook external dependencies, for reentrancy testing) to "test_hooks".

Add sized-delete size-checking functionality. The existing checks are good at finding such issues (on tcache flush), but not so good at pinpointing them. Debug mode can find them, but sometimes debug mode slows down a program so much that hard-to-hit bugs can take a long time to crash. This commit adds functionality to keep programs mostly on their fast paths, while also checking every sized delete argument they get.

Implement use-after-free detection using junk and stash. On deallocation, sampled pointers (specially aligned) get junked and stashed into tcache (to prevent immediate reuse). The expected behavior is to have read-after-free corrupted and stopped by the junk-filling, while write-after-free is checked when flushing the stashed pointers.

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).
