Minor change to mapped_file module, create utility function to verify
file is readonly and map. Also, update the unit test to create temp pb
file instead of writing to the test dir.

This module is repsonsible for finding the storage file location based on a
pb file and then map these storage files into memory using memmap2
crate. The mapped files are cached in a static hashmap in this module.
Note that memmap2 crate has not been introduced to AOSP yet as a 3p
crate. It is in the process of importing to AOSP ATM. So in src/lib.rs,
we only include this module if we are building the target using cargo.
Also, the test storage files: package.map, flag.map and flag.val are
generated based on the storage test aconfig files in
aconfig/aconfig/tests dir. With aconfig create-cache command first to
produce cache files, and then aconfig create-storage command to create
each storage file.
aconfig create-cache --package com.android.aconfig.storage.test_1 --container system --declarations ./storage_test_1.aconfig --cache com.android.aconfig.storage.test_1.cache

bucket index currently is a field in PackageTableNode/FlagTableNode, but this is
purely aux info that is never searilized or deserialized. Therefore we
should remove it from the struct definition. Instead aconfig should
define a wrapper struct that wraps around an instance PackageTableNode/FlagTableNode
as well as aux info like bucket_index.

Introduce a new proto to capture storage file location for each
container. This proto file will appeara as
/metadata/aconfig/storage_file_location.pb. Storage service daemon is
responsible for writing entires to it when a new storage file set is
available. The flag read lib will use this file to find the
corresponding storage file and mmap them.

We no longer build GKIs from the platform tree.
These build commands were neither used nor maintained anymore, so clean
them up to reduce maintenance effort.
Keep the command line options as no-op, so existing scripts that still
specifies the deprecated options don't break.

Currently, EXT4 image building is done in a 2 pass fashion:
First pass: build ext4 image with small margin/headroom, check the
number of block used in the output image
Second pass: Build ext4 image again with an estimated block count from
first pass
The two pass implementation is done to keep image size at a
minimum. Recently some failures in first pass invocation is observed due
to image being undersized. Since we will reduce the image size in 2nd
pass, it's OK to increase the image size estimate during first pass. Add
a headroom 10% of total file size to fix build failures.

Move aconfig storage file definition into its own crate, as flag read
lib will need it as well. The new crate is placed under
aconfig_storage_file dir.

Looks like modules can now be missing "shared_libs" and "static_libs".
Use default values of empty sets where applicable, or check for the
existence of the keys before looking for them.

Previously, aconfig repo is the root directory of aconfig binary crate,
but it also hosts printflags crate inside, and there is no cargo support
for printflags binary crate. In addition, with more aconfig development,
more crates are being added to this repo. Thus this repo should be
configured as a Cargo workspace with multiple crates rather than a
single crate.
Note the top level Cargo.toml file specifies the crates this workspace
carries:
(1) aconfig_protos: the proto library crate that will be used by many other
crates such as aconfig binary crate and printflags binary crate
(2) aconfig: the aconfig binary crate
(3) printflags: the printflags binary crate
(1) aconfig_protos crate setup:
Inside aconfig_protos dir we set up the aconfig_protos crate, the
previously src/proto.rs is now aconfig_protos/src/lib.rs, the build.rs
is carried over to this crate.
(2) aconfig binary crate setup:
Notice its Cargo.toml file claims package dependency on aconfig_protos
crate. It no longer carries proto related module and build.rs file.
(3) printflags binary crate setup:
Similary, notice that in its Cargo.toml file, it claims package
dependency on aconfig_protos crate.
With this setup, we can Cargo build/test each crate individually when
inside a specific crate dir. But we can also run Cargo build/test at
repo root level, which will build/test all the crates in this workplace.
This is the structuring cl. The next cl is to move storage modules into
its own library crate. This storage file library crate will be used by
both aconfig binary crate as well as flag read library crate (to be
created as another new crate here).

Previously, META/apex_info.pb contained only /system/apex apexes. Now,
it has all apexes from all possible partitions.
The main purpose of this file is to caculate the decompressed apex size
when applying OTA. Hence it should have all apexes, not just system
apexes.

Based on the build system feedback, it is better to create storage file
individually per each aconfig command invocation in a makefile. Thus
updating the create-storage command to create one file at a time based
on passed in file selection.
