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.

+OMAP2/3 system tick GPTIMER: use match interrupts rather than overflow interrupts
+
+From: Paul Walmsley <paul@pwsan.com>
+
+On some OMAP3 chips, GPTIMER1 will occasionally decline to interrupt
+the MPU when a timer overflow event occurs.  The timer stops running;
+and TOCR is sometimes incremented; but the MPU apparently never receives
+the interrupt.  This patch was an experiment in using the GPTIMER
+match interrupt to determine if it resolves the problem.
+Unfortunately, it does not; the same problem occurs with match
+interrupts; but this patch is preserved as the base for a
+match+overflow interrupt workaround used in a following patch.
