Make package_extract_file() take an optional third argument which is
the pathname (in the package zip) of a map of don't-care regions to
skip over when writing the file.
Modify syspatch() to take source and target don't-care maps and use
them when patching the system partition.
Add the wipe_block_device() function to do a discard of all data on
the partition.

updater now depends on the GPL'd libraries libsyspatch and libxdelta3,

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.

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.

In order to support multi-stage recovery packages, we add the
set_stage() and get_stage() functions, which store a short string
somewhere it can be accessed across invocations of recovery. We also
add reboot_now() which updater can invoke to immediately reboot the
device, without doing normal recovery cleanup. (It can also choose
whether to boot off the boot or recovery partition.)
If the stage string is of the form "#/#", recovery's UI will be
augmented with a simple indicator of what stage you're in, so it
doesn't look like a reboot loop.

Enable incremental builder to find files that moved, and try to process them via patch + rename, instead of delete + add.
set_perm and set_perm_recursive are no longer used. Delete.

Introduce two new updater functions:
* set_metadata
* set_metadata_recursive
Long term, these functions are intended to be more flexible replacements
for the following methods:
* set_perm
* set_perm_recursive
Usage:
set_metadata("filename", "key1", "value1", "key2", "value2", ...)
set_metadata_recursive("dirname", "key1", "value1", "key2", "value2", ...)
Description:
set_metadata() and set_metadata_recursive() set the attributes on a file/directory
according to the key/value pairs provided. Today, the following keys are
supported:
* uid
* gid
* mode (set_perm_extd only)
* fmode (set_perm_extd_recursive only)
* dmode (set_perm_extd_recursive only)
* selabel
* capabilities
Unknown keys are logged as warnings, but are not fatal errors.
Examples:
* set_metadata("/system/bin/netcfg", "selabel", "u:object_r:system_file:s0");
This sets the SELinux label of /system/bin/netcfg to u:object_r:system_file:s0.
No other changes occur.
* set_metadata("/system/bin/netcfg", "uid", 0, "gid", 3003, "mode", 02750, "selabel", "u:object_r:system_file:s0", "capabilities", 0x0);
This sets /system/bin/netcfg to uid=0, gid=3003, mode=02750,
selinux label=u:object_r:system_file:s0, and clears the capabilities
associated with the file.
* set_metadata_recursive("/system", "uid", 0, "gid", 0, "fmode", 0644, "dmode", 0755, "selabel", "u:object_r:system_file:s0", "capabilities", 0x0);
All files and directories under /system are set to uid=0, gid=0,
and selinux label=u:object_r:system_file:s0. Directories are set to
mode=0755. Files are set to mode=0644 and all capabilities are cleared.

Modify the OTA installer to understand SELinux filesystem labels.
We do this by introducing new set_perm2 / set_perm2_recursive
calls, which understand SELinux filesystem labels. These filesystem
labels are applied at the same time that we apply the
UID / GID / permission changes.
For compatibility, we preserve the behavior of the existing
set_perm / set_perm_recursive calls.
If the destination kernel doesn't support security labels, don't
fail. SELinux isn't enabled on all kernels.

Recovery currently has a random mix of messages printed to stdout and
messages printed to stderr, which can make logs hard to read. Move
everything to stdout.

The bonus data option lets you give an additional blob of uncompressed
data to be used when constructing a patch for chunk #1 of an image.
The same blob must be available at patch time, and can be passed to
the command-line applypatch tool (this feature is not accessible from
edify scripts).
This will be used to reduce the size of recovery-from-boot patches by
storing parts of the recovery ramdisk (the UI images) on the system
partition.

Full OTAs currently fail if the build contains a directory containing
only symlinks, because nothing creates that directory. Change the
symlink() command to create any ancestor directories that don't exist.
They're created as owner root perms 0700 because we assume that in
practice subsequent set_perm_recursive() calls will fix up their
ownership and permissions.

Removes the retouch_binaries and undo_retouch_binaries from updater;
newly generated OTA packages should not call them any more.
Note that applypatch retains the ability to unretouch a file as it
reads it. This will be needed as long as we want to support OTAs from
devices that were installed with retouching.

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).

updater now has a function "wipe_cache();" which causes recovery to
wipe the cache partition after the successful installation of the
package. Move log copying around a bit so logs and the last_install
flag file are copied to cache after it's wiped.
