Add a mandatory option in imgdiff to write the split info (i.e.
patch_size, tgt_size, src_ranges) to file when handling large apks.
Therefore, the caller of imgdiff can create split transfers based on
the info.

This reverts commit 8be0f39fec to reland
the change that removes EXPAND/STRINGIFY macros.
It's error-prone by putting anything into a string (e.g.
EXPAND(RECOVERY_API_VERSION) would become "RECOVER_API_VERSION" if we
forgot to pass -DRECOVERY_API_VERSION=3).
The initial attempt put RECOVERY_API_VERSION into common.h, which might
be included by device-specific codes but without defining that when
compiling the module. This CL avoids the issue by using a constant
in the header, with a static_assert in recovery.cpp that guards the
consistency.
Test: recovery_component_test
Test: Sideload OTAs on bullhead and sailfish respectively.

Otherwise the test may fail after a large number of iterations due to
file open failure.
Bug: 65430057
Test: run recovery_component_test on sailfish for 2000 iterations.

Localized texts only make sense on devices with screens.
Test: Run fake OTA on angler; check the on-screen texts.

By grouping similar kinds together, in an order of types, constants,
ctor/dtor, all other methods and data members.
Also rename ScreenRecoveryUI::density_ to ScreenRecoveryUI::kDensity to
align with others.
Test: mmma bootable/recovery

After the cleanup to WearRecoveryUI, text_top_ now always equals to
((text_row_ + 1) % text_rows_).
Test: Check the recovery UI and 'View recovery logs'.
Change-Id: I69a7f377bbd990db2194f9d3efae257c323c06a8
They're mostly identical to the ones in ScreenRecoveryUI, except for the
(legacy) use of 'text_top_'. Because wear_ui.cpp misses the change in
[1] that uses an alternate screen for viewing recovery logs.
Also clean up the included headers.
[1] commit c049163234 ('Add an alternate
screen for viewing recovery logs.').
Test: Build a wearable target recovery; `View recovery logs`.

Prior to this CL, menu_ is allocated with a fixed length of text_rows_.
However, because we support scrollable menu in wear_ui, there might be
more menu entries than text_rows_, which would lead to out-of-bounds
array access. This CL addresses the issue by switching to std::vector.
Bug: 65416558
Test: Run 'View recovery logs' on angler.
Test: Set large margin height that leaves text_rows less than 21. Then
run 'View recovery logs' with 21 menu entries.

Due to the cache size limit for OTA generation, we used to split large
zip files linearly into pieces and do bsdiff on them. As a result, i) we
lose the advantage of imgdiff; ii) if there's an accidental order change
of some huge files inside the zip, we'll create an insanely large patch.
This patch splits the src&tgt more smartly based on the zip entry_name.
If the entry_name is empty or no matching source is found for a target
chunk, we'll skip adding its source and later do a bsdiff against the
whole split source image (this rarely happens in our use cases except
for the metadata inside a ziparchive).
After the split, the target pieces are continuous and block aligned,
while the sources pieces are mutually exclusive. (Some of the source
blocks may not be used if there's no matching entry_name in the target.)
Then we will generate patches accordingly between each split image
pairs.
Afterwards, if we apply imgpatch to each pair of split source/target
images and add up the patched result, we can get back the original
target image.
For example:
Input: [src_image, tgt_image]
Split: [src-0,tgt-0; src-1,tgt-1, src-2,tgt-2]
Diff: [ patch-0; patch-1; patch-2]
Patch: [(src-0,patch-0)=tgt-0; (src-1,patch-1)=tgt-1;
(src-2,patch-2)=tgt-2;]
Append: [tgt-0 + tgt-1 + tgt-2 = tgt_image]
Peformance:
For the small package in b/34220646, we decrease the patch size of
chrome.apk dramatically from 30M to 400K due to the order change of
two big .so files.
On two versions of angler, I also observe decent patch size decrease.
For chrome.apk, we reduced the size from 5.9M to 3.2M; and for
vevlet.apk from 8.0M to 6.5M.
Bug: 34220646
Test: recovery component test && apply imgdiff & imgpatch on two
chrome.apk
