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] USB: musb: rewrite host periodic endpoint allocation
+
+The current MUSB host code doesn't make use of all the available
+FIFOs in for periodic transfers since it wrongly assumes the RX
+and TX sides of any given hw_ep always share one FIFO.
+
+Change:  use 'in_qh' and 'out_qh' fields of the 'struct musb_hw_ep'
+to check the endpoint's business; get rid of the now-unused 'periodic'
+array in the 'struct musb'.  Also optimize a loop induction variable
+in the endpoint lookup code.
+
+(Based on a previous patch from Ajay Kumar Gupta <ajay.gupta-l0cyMroinI0@public.gmane.org>)
