Most of the changes are trivial.

Also update a dead reference to device_handle_key() in device.h comment,
and add some comments to get_menu_selection() function.

Test: build with clang-tidy

Switch to a Wear-like intro/loop system. We don't have an intro yet,
but hopefully this will let Wear delete more code when they move to N.
Unlike them, we don't hard-code the number of frames: we just look to
see what we have available. We do hard-code the fps though.

Also add a graphics test mode so you can see a demo of the UI components
without having to actually apply an OTA.

Also fix a bug where default locale is null rather than en-US: it's
more useful to show _some_ text if we don't have a locale (which should
only be during development anyway).

This makes it easier for us to deal with arbitrary information at the
top, and means that headers added by specific commands don't overwrite
the default ones.

Add the fingerprint back, but broken up so it fits even on sprout's
display.

Everyone's adding secret key combinations for this anyway, and it's
very useful when debugging.

The current abstract class was a nice idea but has led to a lot of
copy & paste in practice. Right now, no one we know of has any extra
menu items, so let's make the default menu available to everyone.

(If we assume that someone somewhere really does need custom
device-specific menu options, a better API would let them add to
our menu rather than replacing it.)

Create a new recovery UI option to allow the user to view
/cache/recovery/last_log for their device. This gives enhanced
debugging information which may be necessary when a failed
OTA occurs.

Drop support for sideloading OTA packages of the cache partition (a
half-solution that's long since been deprecated by "adb sideload").
Refactor the code to sideload OTA packages from SD cards: remove the
installation code from the file browser.

Rather than depending on the existence of some place to store a file
that is accessible to users on an an unbootable device (eg, a physical
sdcard, external USB drive, etc.), add support for sideloading
packages sent to the device with adb.

This change adds a "minimal adbd" which supports nothing but receiving
a package over adb (with the "adb sideload" command) and storing it to
a fixed filename in the /tmp ramdisk, from where it can be verified
and sideloaded in the usual way.  This should be leave available even
on locked user-build devices.

The user can select "apply package from ADB" from the recovery menu,
which starts minimal-adb mode (shutting down any real adbd that may be
running).  Once minimal-adb has received a package it exits
(restarting real adbd if appropriate) and then verification and
installation of the received package proceeds.

always initialize usb product, vendor, etc. for adb in recovery

Set these values even on non-debuggable builds, so that the mini-adb
now in recovery can work.

Replace the device-specific functions with a class.  Move some of the
key handling (for log visibility toggling and rebooting) into the UI
class.  Fix up the key handling so there is less crosstalk between the
immediate keys and the queued keys (an increasing annoyance on
button-limited devices).
