Move some cache definitions around

[Andreas Jaeger]

To avoid duplication in glibc, I'm moving some definitions from
dl-cache.c to dl-cache.h.  This way I can include "dl-cache.h" in
ldconfig without duplication.

I'm working currently on enhancing ldconfig to support hwcaps and like
to present the smaller patches separatly if possible.  A patch for
ldconfig which uses this will come later.

Can I commit this, Uli?
