on all glibc systems (tested with x86 and x86_64 with a couple of C++
compilers). While not as ideal as the malloc_hooks method, it does
have the advantage of working with threads.
* Modified malloc_hooks component to properly follow prefix rule. No
functionality changes
* Make the memory framework only chose one component, and modify all
components to set priority to 20, except malloc-interpose, which is
at 10. This means that on Linux, malloc_hooks will be used unless
threads are enabled, since I think malloc_hooks is a better design
choice when we can use it
