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.

Refactor time_* into nstime_*. Use a single uint64_t in nstime_t to store nanoseconds rather than using struct timespec. This reduces fragility around conversions between long and uint64_t, especially missing casts that only cause problems on 32-bit platforms.

Refine nstime_update(). Add missing #include <time.h>. The critical time facilities appear to have been transitively included via unistd.h and sys/time.h, but in principle this omission was capable of having caused clock_gettime(CLOCK_MONOTONIC, ...) to have been overlooked in favor of gettimeofday(), which in turn could cause spurious non-monotonic time updates. Refactor nstime_get() out of nstime_update() and add configure tests for all variants. Add CLOCK_MONOTONIC_RAW support (Linux-specific) and mach_absolute_time() support (OS X-specific). Do not fall back to clock_gettime(CLOCK_REALTIME, ...). This was a fragile Linux-specific workaround, which we're unlikely to use at all now that clock_gettime(CLOCK_MONOTONIC_RAW, ...) is supported, and if we have no choice besides non-monotonic clocks, gettimeofday() is only incrementally worse.

Do not advance decay epoch when time goes backwards. Instead, move the epoch backward in time. Additionally, add nstime_monotonic() and use it in debug builds to assert that time only goes backward if nstime_update() is using a non-monotonic time source.

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

Refactor time_* into nstime_*. Use a single uint64_t in nstime_t to store nanoseconds rather than using struct timespec. This reduces fragility around conversions between long and uint64_t, especially missing casts that only cause problems on 32-bit platforms.

nstime_t old_time;

Refine nstime_update(). Add missing #include <time.h>. The critical time facilities appear to have been transitively included via unistd.h and sys/time.h, but in principle this omission was capable of having caused clock_gettime(CLOCK_MONOTONIC, ...) to have been overlooked in favor of gettimeofday(), which in turn could cause spurious non-monotonic time updates. Refactor nstime_get() out of nstime_update() and add configure tests for all variants. Add CLOCK_MONOTONIC_RAW support (Linux-specific) and mach_absolute_time() support (OS X-specific). Do not fall back to clock_gettime(CLOCK_REALTIME, ...). This was a fragile Linux-specific workaround, which we're unlikely to use at all now that clock_gettime(CLOCK_MONOTONIC_RAW, ...) is supported, and if we have no choice besides non-monotonic clocks, gettimeofday() is only incrementally worse.
