Major layout change to the packages directory

Having one monolithic packages directory makes it hard to find things
and is generally overwhelming. This commit splits it into several
logical sections roughly based on function, recipes.txt gives more
information about the classifications used.

The opportunity is also used to switch from "packages" to "recipes"
as used in OpenEmbedded as the term "packages" can be confusing to
people and has many different meanings.

Not all recipes have been classified yet, this is just a first pass
at separating things out. Some packages are moved to meta-extras as
they're no longer actively used or maintained.

+Subject: [PATCH] DSS2: VRFB rotation and mirroring implemented.
+
+DSS2 modified to accept the rotation_type input
+to get the dma or VRFB rotation.
+
+DSS2: VRFB: Changed to pass DSS mode to vrfb_setup instead of Bpp.
+
+VRFB size registers requires the width to be halved when the
+mode is YUV or UYVY.  So modifed to pass the mode to omap_vrfb_setup
+function.
+
+Code added by Tim Yamin for few bug fixes
