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.

When creating a new file using open(..., O_CREAT), it is an error
to fail to specify a creation mode. If a mode is not specified, a
random stack provided value is used as the "mode".
This will become a compile error in a future Android change.

The applypatch function is somewhat sloppy about freeing memory (since
it was originally a standalone binary). Fix some of that.

An accidental variable declaration ("int enough_space = ..." instead
of "enough_space = " inside a block) shadowing the real one meant we
were always using the copy-to-cache path for patching, even when not
necessary. Remove it. Enforce an absolute minimum of free space as
well, to avoid running into problems patching small files, now that
the copy-to-cache path is (inadvertently) well-tested.

When restarting a patch from crashing in the middle of a large file,
we're not finding the correct patch to apply to the copy saved in
cache.

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.

Let applypatch read and write EMMC partitions as well as MTD ones.
This enables incremental updates that include boot image changes, as
well as OTA of new recovery partitions.

Change the applypatch function to take meaningful arguments instead of
argc and argv. Move all the parsing of arguments into main.c (for the
standalone binary) and into install.c (for the updater function).
applypatch() takes patches as Value objects, so we can pass in blobs
extracted from the package without ever writing them to temp files.
The patching code is changed to read the patch from memory instead of
a file.
A bunch of compiler warnings (mostly about signed vs unsigned types)
are fixed.
Support for the IMGDIFF1 format is dropped. (We've been generating
IMGDIFF2 packages for some time now.)

- 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.
