(cherry picked from commit 8c70d4de97)
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.
Bug: 68016761
Test: Generate an incremental OTA package from images with incomplete
block list. Check the imgdiff stats report.

This variable can be set in BoardConfig.mk to specify a list of
additional paths that contain PGO profiles. These directories are
searched before the predefined paths in soong/cc/pgo.go while finding
PGO profiles.
Test: Set this variable in a BoardConfig and verify that such profiles
are found and that these paths are searched before the predefined paths
in soong/cc/pgo.go.

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)

The bpfloader is a executable binary used by netd to load and attach
networking related bpf program at run time. It need to be flashed to
device when updating the system image. Currently this binary is only
used by devices with kernel version 4.9 or above.
Test: hikey boot and bpf program show up under sys/fs/bpf

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
