This CL adds a new flag '--skip_postinstall' that allows skipping all
the postinstall hooks when generating an A/B OTA package (default:
False). Note that this discards ALL the hooks, including non-optional
ones. Should only be used if caller knows it's safe to do so (e.g. all
the postinstall work is to dexopt apps and a data wipe will happen
immediately after).

Since we have been carrying test certificates in testdata/ for other
tests, do the same for test_sign_target_files_apks.py. Copy
verity.x509.pem from build/target/product/security/ to testdata/ for
that purpose.
Also capture the stderr output in ReplaceVerityKeyId().

(cherry picked from commit 6048121485)
When target defines 'BOARD_EXT4_SHARE_DUP_BLOCKS := true', the generated
system/vendor images may contain shared blocks (i.e. some blocks will
show up in multiple files' block list), which violates the current
assumptions in BBOTA script.
This CL allows generating BBOTAs by considering the first occurrence as
the "owner" of the shared blocks. All the later users of the shared
blocks will have an incomplete block list, whose RangeSet's will be
tagged with 'uses_shared_blocks'.
Files with 'uses_shared_blocks' tag will not be diff'd with imgdiff,
potentially with patch size penalty. Such files will be accounted for in
imgdiff stats report, where we can revisit for a better solution.
Bug: 64109868
Test: Generate BBOTA full and incremental package with targets defining
'BOARD_EXT4_SHARE_DUP_BLOCKS := true'.

This CL uses the 'incomplete' tag to skip applying imgdiff to files with
incomplete block list. It's not the ideal fix to address the holes in
ext4 images, but would unhide other imgdiff issues covered by the
unconditional fallback.

Test: Generate an incremental OTA package from images with incomplete
block list. Check the imgdiff stats report.

pylint complains about undefined `diff_done`:
W:754, 8: Global variable 'diff_done' undefined at the module level (global-variable-undefined)
W:820,14: Global variable 'diff_done' undefined at the module level (global-variable-undefined)
It would still warn about using global statement after adding the
definition.
W:859, 8: Using the global statement (global-statement)
W:925,14: Using the global statement (global-statement)
This CL computes 'diff_done' via 'len(diff_queue)' instead. It also
moves the progress reporting _before_ the diff work. This way it avoids
showing 100% progress with still changing filenames (because multiple
workers could see an empty queue simultaneously upon finishing their own
works).
There're possible alternatives, such as using the 'nonlocal' keyword in
Python 3 (which we're not there yet), or by using mutable object instead
(e.g. 'diff_done = [0]'). This CL looks cleaner, since it just kills the
var.
Test: Generate a BBOTA incremental. Check the on-screen progress
report.
Test: `pylint --rcfile=pylintrc blockimgdiff.py` no longer complains
about the global diff_done.

The secondary payload should always be applied with
SWITCH_SLOT_ON_REBOOT=0. This CL moves the 'secondary' parameter from
Payload.WriteToZip() to Payload.__init__(). So it can append the flag to
secondary/payload_properties.txt.

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
...

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.
