New Formula: libraw

New Formula: libraw  This is a library for handling RAW images.
There is a dep on little-cms to enable ICC Color Profiles.  The
optional GPL2 and GPL3 demosaic packs are also built with this.
The library is stable and has a consistent API that supports
reading, decoding, and unpacking of RAW image files, along with
conversion, interpolation, and output.  It was compiled and tested
with clang-2.0, llvm 2335, and gcc-4.2.1 on OSX 10.6.8 x86_64.

Closes #7684.
