b511232fcd Refactor/fix background_thread/percpu_arena bootstrapping.
Refactor bootstrapping such that dlsym() is called during the
bootstrapping phase that can tolerate reentrant allocation.

18a83681cf Refactor (MALLOCX_ARENA_MAX + 1) to be MALLOCX_ARENA_LIMIT.
This resolves #673.

4403c9ab44 Remove --disable-tcache.
Simplify configuration by removing the --disable-tcache option, but
replace the testing for that configuration with
--with-malloc-conf=tcache:false.

Fix the thread.arena and thread.tcache.flush mallctls to work correctly
if tcache is disabled.

This partially resolves #580.

5aa46f027d Bypass extent tracking for auto arenas.
Tracking extents is required by arena_reset.  To support this, the extent
linkage was used for tracking 1) large allocations, and 2) full slabs.  However
modifying the extent linkage could be an expensive operation as it likely incurs
cache misses.  Since we forbid arena_reset on auto arenas, let's bypass the
linkage operations for auto arenas.

c2fcf9c2cf Switch to fine-grained reentrancy support.
Previously we had a general detection and support of reentrancy, at the cost of
having branches and inc / dec operations on fast paths.  To avoid taxing fast
paths, we move the reentrancy operations onto tsd slow state, and only modify
reentrancy level around external calls (that might trigger reentrancy).

743d940dc3 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.
