These replace $USER and `hostname`, which will soon become stable values
due to sandboxing the build on Linux.

This is just a hash of the current.txt and system-current.txt right now,
though it may expand to include other API surfaces in the future.
Once prebuilts/sdk/current is populated with api_fingerprint.txt files,
we can use those for unbundled builds, but until then, just use the
PLATFORM_PREVIEW_SDK_VERSION as a placeholder.
MD5 was just the most convenient, since we don't have a sha tool that we
can use on Mac currently. I'm hoping we can get a toybox-based tool in
the future that standardizes that, but we aren't currently using sha*sum
from toybox on Linux, much less on Darwin yet.

Package size will be unintended large if we stash more blocks than the
stash limit specified by the cache size. To reduce the maximum size of
simultaneous stashed blocks, we will inevitably convert some 'diff'
commands to 'new' commands.
To mitigate the impact, we add a new function to smartly select the
transfers to convert based on their patch size and compressed size.
This cl converts the transfers that have a larger patch size than the
compressed target sizes. And there's a slightly improvement in the
final package size: from 194M -> 185M.

This change excludes retrofit devices from getting a third metadata

This prints the uid map in a very simple format, with
AID_CONSTANT<space>uid
on each line. This is super easy for other tools to
parse, and generate their own mappings, without requiring
edits to fs_config_generator.py itself.

We will call it at an earlier time to compute the patch size; and

The code to manage citing empty <partition>/etc/fs_config_{files|dirs}
content by specifically setting the file(s) to access mode 00000 is
bitrotted and ill-suited for multiple partitions and was written for
a more paranoid time when DAC and MAC rules were not nearly as mature.
Striking out the complications as it affected deterministic results.

For some internal branches, vendor.img isn't built, so there
is no need to build super image / super split images there.

Mechanical extension of mount directories to also support product/
and product_services/ as individually supplied images.
NB: In the distant past, a prototype placing the make rules into a
macro was rejected as too difficult to maintain within the macro
rules, so rules are rolled-out to make them easy to understand.

Setting 'uses_shared_blocks' indicates that the block list for a given
file is incomplete, as some of the blocks are "owned" by others. As a
result, such a file will be skipped from imgdiff'ing.
This CL makes a copy of the original block list before removing the
shared blocks. It uses the original RangeSet as the value of
extra['uses_shared_blocks']. validate_target_files.py will try to read
the file as in the original RangeSet, unless the original list is also
incomplete or has non-monotonic ranges.
Test: Run validate_target_files on a target that uses
`BOARD_EXT4_SHARE_DUP_BLOCKS := true`.

Pages in .data.rel.ro are always dirty. Move whatever we can to
.rodata so that we reduce memory pressure.
The size of rodata, text, and data.rel.ro sections of libc on cuttlefish
before/after this change:
rodata: 0xfd70 -> 0x101d0 (+1120 bytes)
text: 0xb5715 -> 0xb56e5 (-48 bytes)
data.rel.ro: 0x57e0 -> 0x5230 (-1456 bytes)
While this change alone doesn't reduce the number of dirty pages
from data.rel.ro on cuttlefish, it is a step in that direction.

For non-retrofit (launch) devices, super.img is used for factory, so
source images should be from target_files.
In this change, build-superimage-target procedure is converted to a
more flexible script so that it can be built.
