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 assumes that the metadata is correctly defined in fstab.
Which apparently some devices don't do.

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.

Also provide a default implementation of CheckKey that's reasonable
for many devices (those that have power and volume keys).

libext4_utils now calls libselinux in order to determine the

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).
Change-Id: I698f6fd21c67a1e55429312a0484b6c393cad46f
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).

Remove the wacky notion of "roots" and "root paths" (those things that
look like "FOO:some/path" instead of just "/foo/some/path"). Let each
device specify its own table of available partitions and how to mount
them (needed for devices that use both MTD/yaffs2 and EMMC/ext4
partitions).
(Cherrypicked from gingerbread w/slight edits.)

Separate files for retouch functionality are in minelf/*
ASLR for shared libraries is controlled by "-a" in ota_from_target_files.
Binary files are self-contained. Retouch logic can recover from crashes.

- Move applypatch to this package (from build).
- Add a rudimentary type system to edify: instead of just returning a
char*, functions now return a Value*, which is a struct that can
carry different types of value (currently just STRING and BLOB).
Convert all functions to this new scheme.
- Change the one-argument form of package_extract_file to return a
Value of the new BLOB type.
- Add read_file() to load a local file and return a blob, and
sha1_check() to test a blob (or string) against a set of possible
sha1s. read_file() uses the file-loading code from applypatch so it
can read MTD partitions as well.
This is the start of better integration between applypatch and the
rest of edify.

add a simple unit test for the OTA package verifier
This change enables/disables the Encrypted file systems feature. It reads some properties form the data partition, wipes the partition out, and then rewrites the proper properties again into the data partition to signal that encrypted FS are enabled.
Yank all the code to install OTA packages out of the recovery binary
itself. Now packages are installed by a binary included in the
package (run as a child of recovery), so we can make improvements in
the installation process without waiting for a new release to use
them.
To do a firmware-install-on-reboot, the update binary tells recovery
what file to install before rebooting. Let this file be specified as
"PACKAGE:<foo>" to indicate taking the file out of the OTA package,
avoiding an extra copy to /tmp. Bump the API version number to
reflect this change.

edify extensions for OTA package installation, part 1
Adds the following edify functions:
mount unmount format show_progress delete delete_recursive
package_extract symlink set_perm set_perm_recursive
This set is enough to extract and install the system part of a (full)
OTA package.
Adds the updater binary that extracts an edify script from the OTA
package and then executes it. Minor changes to the edify core (adds a
sleep() builtin for debugging, adds "." to the set of characters that
can appear in an unquoted string).
Take some device-specific details of the recovery UI (eg, what keys to
press to bring up the interface and perform actions, exact text of the
menu, etc.) and split them out into separate C functions. Arrange to
take implementations of those functions from the appropriate vendor
directory at build time. Provide a default implementation in case no
vendor-specific one is available.
them from an external file in the recovery image. Use the
test-keys for all builds.
