Flags belong to a namespace. Update the proto files to reflect this.
Config files can only refer to a single namespace. Override files can
refer to multiple namespaces; an override directive for a flag in a
different namespace than the one represented by the cache will be
silently ignored.
Rename the proto messages to make it more clear what they are. Propagate
this change through the wrappers in aconfig.rs and the rest of the code.
Also, settle on Tracepoint instead of TracePoint.

Introduce a new protobuf format to represent the all flags parsed by
aconfig. This data in this new format is similar to that of the internal
cache object, but the protobuf is a public API for other tools to
consume and any changes to the proto spec must be backwards compatible.
When aconfig has matured more, Cache can potentially be rewritten to
work with proto structs directly, removing some of the hand-written
wrapper structs and the logic to convert to and from the proto structs.
At this point, the intermediate json format can be replaced by the
protobuf dump.
Also, teach `aconfig dump` to accept an --out <file> argument (default:
stdout).
Also, teach `aconfig dump` to read more than once cache file.
Note: the new protobuf fields refer to existing fields. It would make
sense to split the .proto file in one for input and one for output
formats, and import the common messages, but the Android build system
and cargo will need different import paths. Keep the definitions in the
same file to circumvent this problem.

Improve how the flag values (state, permission) are tracked when parsing
config and override files: migrate from a raw string to a proper struct,
as this will make it easier when aconfig will output this data in some
structured format for other tools to consume.
Also, rename Cache.debug to Cache.trace.

* changes:
aconfig: add support for changing flag value based on build
aconfig: introduce cache
aconfig: define Aconfig proto
aconfig: add support for cargo
Teach aconfig about build IDs (continuously increasing integers). Extend
the aconfig file format to allow flags to say "by default, my value is
X, but starting from build ID A, it's Y, and from build ID B, it's Z".

Introduce the Cache struct to represent parsed and verified aconfig and
override content. Most commands in aconfig will work of an existing
cache file, eliminating the need to re-read the input every time.
Restructure main.rs to use clap to create a proper command line
interface with support for sub-commands. main.rs is responsible for
parsing the command line, performing disk I/O and calling the correct
subcommand implementation (in commands.rs).
To simplify unit tests, subcommands never perform explicit I/O; instead
they only work with Read and Write traits.
Also add dependencies on clap, serde and serde_json.

Fill in aconfig.proto. Define Aconfig definitions (for introducing flags
and setting their values) and Overrides (for overriding flags regardless
of what their definitions say). More changes to the proto schema are
expected when more of the aconfig project is outlined.
Use proto2 instead of proto3: this will cause the protobuf text parser
to error on missing fields instead of returning a default value which is
ambiguous, especially for booleans. (Also, the text protobuf parser
doesn't provide good error messages: if the input is missing a field,
the error is always "1:1: Message not initialized").
Unfortunately the generated Rust wrappers around the proto structs land
in an external crate, which prevents aconfig from adding new impl
blocks. Circumvent this by converting the data read from proto into
structs defined in the aconfig crate.
Change main.rs to parse (static) text proto.
Also add dependency on anyhow.

Officially, aconfig is build using the Android tool-chain. However, to
speed up the local development cycle, add support for building with
cargo.
While it is possible to tell cargo to place the build artifacts outside
the source tree, there is no way to tell it to not generate the cargo
lock file in the same directory as Cargo.toml. Add a .gitignore to
ignore Cargo.lock and the target directory.
The way the Android build system and cargo generates code from the
protobuf files is slightly different. Tell cargo to enable the "cargo"
feature and introduce src/protos.rs to hide this difference from the
rest of the aconfig source.

Introduce a new tool, aconfig, to manage build time configurations, such
as feature flags.
This CL adds a project skeleton. Later CLs will add the actual
implementation.
Note: there is no need for an explicit TEST_MAPPING file;
rust_test_host are automatically included in host-unit-tests and
explicitly adding these tests via TEST_MAPPING will cause an error.
