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] musb: make initial HNP roleswitch work (v2)
+
+Minor HNP bugfixes, so the initial role switch works:
+
+ - A-Device:
+     * disconnect-during-suspend enters A_PERIPHERAL state
+     * kill OTG timer after reset as A_PERIPHERAL ...
+     * ... and also pass that reset to the gadget
+     * once HNP succeeds, clear the "ignore_disconnect" flag
+     * from A_PERIPHERAL, disconnect transitions to A_WAIT_BCON
+
+ - B-Device:
+     * kill OTG timer on entry to B_HOST state (HNP succeeded)
+     * once HNP succeeds, clear "ignore_disconnect" flag
+     * kick the root hub only _after_ the state is adjusted
+
+Other state transitions are left alone.  Notably, exit paths from
+the "roles have switched" state ... A_PERIPHERAL handling of that
+stays seriously broken.
