We have a couple of active imgdiff workarounds (and likely with one more
inbounding that allows having shared blocks in ext4 image). Most of
these workarounds need extending imgdiff's capability. While us not
getting there anytime soon, collect the stats to better understand the
impact of each kind so we can prioritize accordingly.
A sample report is as follows.
Imgdiff Stats Report
========================
APK files diff'd with imgdiff (count: 88)
-------------------------------------------
/system/priv-app/Shell/Shell.apk
...
Large APK files split and diff'd with imgdiff (count: 4)
----------------------------------------------------------
/system/priv-app/Settings/Settings.apk

(cherry picked from commit 586c8821083ad1bec874d6de5ab378dbb47dee58)
In Transfer class, unbundle 'intact' with the monotonicity of the input
ranges. Negate the logic of 'intact', and thus rename it to 'trimmed'.
Move this property from an attribute of Transfer class as the one in
RangeSet.extra. 'trimmed' indicates whether the source / target ranges
have been modified after creating the Transfer() instance.
The logic that determines whether we can apply imgdiff has been
refactored and consolidated into BlockImageDiff.CanUseImgdiff(). Now
both of the two paths call this single copy, i.e. the one that detects
large APKs (before creating Transfer()'s), and the other that's about to
generate the patch for a given Transfer instance.

There is an internal buffer in bionic for user/group names that is 32
characters long including the trailing null, so we must restrict the
length of these names during compile time.

These entries are vendor provided and belong on the /vendor partition.

So they can be used by art/test/Android.run-test.mk.
Also remove the line wrapping, which was inserting extra characters
at the beginning of the result, and add a sanity check.

Packages would use proguard rules from their
LOCAL_STATIC_ANDROID_LIBRARIES, but other libraries wouldn't propagate
the rules from their LOCAL_STATIC_ANDROID_LIBRARIES.

due to missing header.jar, build was broken with error:
"android_stubs_current_intermediates/classes-header.jar needed by
android-support-annotations_intermediates/classes-turbine.jar,
missing and no known rule to make it"

This was ok for apk because they are in different parent directory.
