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.

Add --with-mangling. Add the --with-mangling configure option, which can be used to specify name mangling on a per public symbol basis that takes precedence over --with-jemalloc-prefix. Expose the memalign() and valloc() overrides even if --with-jemalloc-prefix is specified. This change does no real harm, and simplifies the code.
