Add --with-mangling.

Browse source 
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.

* In many cases it is more convenient to manually prefix allocator function
* calls than to let macros do it automatically, particularly when using
* multiple allocators simultaneously. Define JEMALLOC_MANGLE before
* #include'ing jemalloc.h in order to cause name mangling that corresponds to
* the API prefixing.
