This commit introduces a prebuilt ELF binaries checker. The checker
will check:
1. Whether all DT_NEEDED shared libraries are specified in
`shared_libs` (Android.bp) or `LOCAL_SHARED_LIBRARIES` (Android.mk).
2. Whether all undefined symbols in the prebuilt binary can be resolved
to defined symbols exported by its dependencies.
This ensures that prebuilt binaries won't silently become ABI
incompatible.
To check the prebuilt binaries, all of the dependencies must be
specified in `shared_libs` (Android.bp) or `LOCAL_SHARED_LIBRARIES`
(Android.mk).
If your prebuilt binaries cannot be checked for some reason, you may add
the following property to Android.bp:
check_elf_files: false,
Or, add the following setting to Android.mk:
LOCAL_CHECK_ELF_FILES := false

- When removing a partition, BlockDifference() object
will have tgt=EmptyImage(). Fix the asserts accordingly.
Also, BlockDifference object now allow tgt=None case.
- When adding a partition, BlockDifference() object
will have src=None. Fix the asserts accordingly.
Also, add unit tests to DynamicPartitionsDifference.

We cannot simultaneously stash more blocks than the size limit imposed by
the cache size. As a result, some 'diff' commands will be inevitably
converted to new. We used to do this conversion blindly when iterating
through the transfer list. This leads to an unintended large package.
In order to choose the right transfers to convert, we calculate the size
of the compressed data, and build a heuristic about the package size
increase to remove each stash blocks. After the process, the given
package size for the watch device further reduces from 186M->155M.
In some rare cases, the removed stashed blocks don't directly contribute
to the maximum simultaneously stashed size. For example,
stash A: 10 blocks
stash B: 5 blocks
free B: 5 blocks <-- stash B has been freed before we reach max stashed blocks
stash C: 10 blocks
Converting these blocks lead to an uncertain result. On one hand, patches
are generally smaller than the new data; while on the other hand, the
regenerated graph may have fewer order violation and thus give some size
reduction. But these cases are rare and it seems an overkill to consider all
possible scenarios here.

Test: build non-A/B incrementals and check the size
(p.s. it can be tested on all target files with customed cache threshold)

To address problems creating real tiny filesystem placeholders,
make sure extra spare inodes margin is greater than 0.
For initial estimate we add 4% of total we request at least 8.
For second pass estimate we add 0.2% of total we request at least 1.
We bumped up the margin for zie on the second pass to 0.3% as the
value was too close on one of the builds.

We used to create the intermediate output file as a tempfile, when
adding images to a given zip file. This CL changes OutputFile to write
intermediate files under the given input dir (i.e. OPTIONS.input_tmp
that holds the unzipped files), if the final destination is a zip
archive. This allows image building codes finding the generated images
at consistent locations. The intermediate files will be cleaned up as
part of OPTIONS.input_tmp.

inode-size will jump around based on filesystem size, however
readonly Android system partitions have a specific pattern of
xattr associated with sepolicy and 256 is the most efficient at
absorbing the content.

We used to build retrofit full OTA package as long as
PRODUCT_RETROFIT_DYNAMIC_PARTITIONS is true. This doesn't work with AOSP
targets that have the flag set but without any available vendor image.
This CL detects such a condition and uses a separate flag to guard the
retrofit OTA building as well as the split super images generation.

soong_ui is passing the Android.mk file list to Kati, and it ignores
Android.mk files found via symlinks, so we don't need the workarounds
for build/make/target/board/Android.mk and build/target/board/Android.mk
both existing.
We've got dist support in Soong now, so we can remove the signapk
