[Cook] fingerprint => md5

[Peter Miller]

Hi Folks,

I am thinking of moving Cook to use the MD5 algorithm from libgcrypt,
rather than my home-grown fingerprints from circa 1991.  It has the
potential to be *much* faster when fingerprinting large files (I notice
this when building cd-rom iso images, for example).  It will cause a
larger-than-usual rebuild immediately after upgrade, but will not cause
Cook to build too little, and will settle down to the usual behaviour
after that first build.

An alternative is SHA256 from the same library.

What say you?
