- 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.

# A script for testing imgdiff/applypatch. It takes two full OTA

# packages as arguments. It generates (on the host) patches for all
|
|
# the zip/jar/apk files they have in common, as well as boot and
|
|
# recovery images. It then applies the patches on the device (or
|
|
# emulator) and checks that the resulting file is correct.
