update_verifier checks the integrity of the updated system and vendor
partitions on the first boot post an A/B OTA update. It marks the
current slot as having booted successfully if it passes the verification.
This CL doesn't perform any actual verification work which will be
addressed in follow-up CLs.

These are already getting libc++, so it isn't necessary. If any of the
other static libraries (such as adb) use new or delete from libc++,
there will be symbol collisions.

(cherry picked from commit e49a9e527a)
Every watch has a (mostly identical) copy of the wear_ui. Factor them
out into a single copy for easier maintenance. Device-specific settings
should be defined in recovery_ui.cpp that inherits WearRecoveryUI class.

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.

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.)

I think everything left now is here to stay (services.c might get
massaged in to libadbd if it gets refactored).

adb.h has diverged a bit, so that one will be more involved, but these
three are all trivial, unimportant changes.

This include path was needed because system/vold/cryptfs.h included an
OpenSSL header just to get the length of a SHA-256 hash. This has been
fixed in https://android-review.googlesource.com/#/c/124477/1.

Make a fuse filesystem that sits on top of the selected package file
on the sdcard, so we can verify that the file contents don't change
while being read and avoid copying the file to /tmp (that is, RAM)
before verifying and installing it.

Split the adb-specific portions (fetching a block from the adb host
and closing the connections) out from the rest of the FUSE filesystem
code, so that we can reuse the fuse stuff for installing off sdcards
as well.

This adds F2FS support
- for wiping a device
- for the install "format" command.
Note: crypto data in "footer" with a default/negative length
is not supported, unlike with "ext4".

Recovery now draws directly to the framebuffer by rolling its own
graphics code, rather than depending on libpixelflinger.
The recovery UI is modified slightly to eliminate operations that are
slow with the software implementation: when the text display / menu is
turned on, it now appears on a black background instead of a dimmed
version of the recovery icon.
There's probably substantial room for optimization of the graphics
operations.

Older versions of android supported an ASLR system where binaries were
randomly twiddled at OTA install time. Remove support for this; we
now use the ASLR support in the linux kernel.

uncrypt can read a file on an encrypted filesystem and rewrite it to
the same blocks on the underlying (unencrypted) block device. This
destroys the contents of the file as far as the encrypted filesystem
is concerned, but allows the data to be read without the encryption
key if you know which blocks of the raw device to access. uncrypt
produces a "block map" file which lists the blocks that contain the file.
For unencrypted filesystem, uncrypt will produce the block map without
touching the data.

Changes minzip and recovery's file signature verification to work on
memory regions, rather than files.
For packages which are regular files, install.cpp now mmap()s them
into memory and then passes the mapped memory to the verifier and to
the minzip library.
Support for files which are raw block maps (which will be used when we
have packages written to encrypted data partitions) is present but
largely untested so far.

This adds support for key version 5 which is an EC key using the NIST
P-256 curve parameters. OTAs may be signed with these keys using the
ECDSA signature algorithm with SHA-256.

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.

Move the key for handling keys from ScreenRecoveryUI to RecoveryUI, so
it can be used by devices without screens. Remove the UIParameters
struct and replace it with some new member variables in
ScreenRecoveryUI.

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).

Move all the functions in ui.c to be members of a ScreenRecoveryUI
class, which is a subclass of an abstract RecoveryUI class. Recovery
then creates a global singleton instance of this class and then invoke
the methods to drive the UI. We use this to allow substitution of a
different RecoveryUI implementation for devices with radically
different form factors (eg, that don't have a screen).
