Refactor jemalloc.c into multiple source files. Fix a stats bug in large object curruns accounting. Replace tcache_bin_fill() with arena_tcache_fill(), and fix a bug in an OOM error path. Fix API name mangling to coexist with __attribute__((malloc)).

Use arena dss prec instead of default for huge allocs. Pass a dss_prec_t parameter to huge_{m,p,r}alloc instead of defaulting to the chunk dss prec.

Extract profiling code from [re]allocation functions. Extract profiling code from malloc(), imemalign(), calloc(), realloc(), mallocx(), rallocx(), and xallocx(). This slightly reduces the amount of code compiled into the fast paths, but the primary benefit is the combinatorial complexity reduction. Simplify iralloc[t]() by creating a separate ixalloc() that handles the no-move cases. Further simplify [mrxn]allocx() (and by implication [mrn]allocm()) to make request size overflows due to size class and/or alignment constraints trigger undefined behavior (detected by debug-only assertions). Report ENOMEM rather than EINVAL if an OOM occurs during heap profiling backtrace creation in imemalign(). This bug impacted posix_memalign() and aligned_alloc().

Add {,r,s,d}allocm(). Add allocm(), rallocm(), sallocm(), and dallocm(), which are a functional superset of malloc(), calloc(), posix_memalign(), malloc_usable_size(), and free().

Add junk/zero filling unit tests, and fix discovered bugs. Fix growing large reallocation to junk fill new space. Fix huge deallocation to junk fill when munmap is disabled.

Use mremap(2) for huge realloc(). If mremap(2) is available and supports MREMAP_FIXED, use it for huge realloc(). Initialize rtree later during bootstrapping, so that --enable-debug --enable-dss works. Fix a minor swap_avail stats bug.

Fix threads-related profiling bugs. Initialize bt2cnt_tsd so that cleanup at thread exit actually happens. Associate (prof_ctx_t *) with allocated objects, rather than (prof_thr_cnt_t *). Each thread must always operate on its own (prof_thr_cnt_t *), and an object may outlive the thread that allocated it.

Fix fork-related bugs. Acquire/release arena bin locks as part of the prefork/postfork. This bug made deadlock in the child between fork and exec a possibility. Split jemalloc_postfork() into jemalloc_postfork_{parent,child}() so that the child can reinitialize mutexes rather than unlocking them. In practice, this bug tended not to cause problems.
