Before java code will directly use the flag name as the method name.
This change adds funciton to try the best to convert flag name to
camelCase, and then use the camelCase string as the method name in the
generated code.

The Java codegen may translate flag names (snake_case) to Java
camelCase, dropping the underscores. The flags a_b and a__b will
translate to the same camelCase form, which is ambiguous.
Circumvent this problem by disallowing consecutive underscores in flag
names, flag namespaces, and packages.

Add integration tests for Java. This test setup verifies that
- the build system calls aconfig to generate a Java library
- the Java test compiles against the auto-generated library
- the auto-generated code returns expected values
Similar integration tests for C++ and Rust will be added in follow-up
CLs.
Note: the build does not currently support specifying that
tests/*.values should be applied, so the test flags will all be assigned
the defaults. A later CL will fix this.

Also, update examples to use dots in the package fields.
Also, remove unnecessary #include from the auto-generated C++ code: the

Add a new "create-device-config-sysprops" command that works like
"create-device-config-defaults" but for system properties.
DeviceConfig is a Java service, and will mirror (some of) its values by
setting system properties in the persist.device_config namespace. Native
code will access DeviceConfig (actually, the system properties) via the
server_configurable_flags library.
The new command writes a file that can be appended to /system/build.prop
to pre-populate persist.device_config before DeviceConfig has started.
Like create-device-config-defaults, the new command skips READ_ONLY
flags.

DeviceConfig is the backend for READ_WRITE flags.
Add a new command "create-device-config-defaults" to create a file that
DeviceConfig will read to pre-populate its data store on first init.
This will be used to quickly switch flag values during CI tests:
rebuilding and reflashing a device would have the same effect, but would
be costlier. This feature is not expected to be used outside CI tests.
Note: because DeviceConfig only works with READ_WRITE flags, the
generated file excludes READ_ONLY flags.

Pass the Cache argument to command::create_<lang>_lib functions by value
instead of by reference, to align with other commands.
The intended ownership flow is as follows:
- main creates objects based on command line arguments
- main hands commands ownership of the objects
- command processes the objects
- command gives main ownership of any generated output
- main writes the output to file
Rationale: commands.rs is a unit testable version of main, and to the
rest of aconfig, acts as the top level entry point; main.rs exists only
to parse command line arguments and perform I/O.

The namespace and flag names will be used as identifiers in the
auto-generated code. Place restrictions on what constitutes a valid
name.
Valid identifiers are those that match /[a-z][a-z0-9_]/. aconfig
explicitly does not implement any automatic translation to make names
valid identifiers: this sidesteps potential conflicts such as "foo.bar"
and "foo_bar" mapping to the same name if dots were translated to
underscores.

Add a new `create-rust-lib` command to generate Rust code. The output is
a src/lib.rs file; the build system is assumed to set the generated
crate's name.
For READ_ONLY flags, the generated code returns a hard-coded true or false.
For READ_WRITE flags, the generated code reaches out to DeviceConfig via
the cc_library server_configurable_flags via the
libprofcollect_libflags_rust Rust bindings. The build system is assumed
to add this to the generated crate's dependencies.
Note: libprofcollect_libflags_rust seems generic enough that it should
be moved to an official Rust wrapper for server_configurable_flags. This
is tracked in b/284096062.
Summary of module the built system is assumed to wrap the auto-generated
code in:
rust_library {
name: "lib<namespace>_rs",
crate_name: "<namespace>_rs",
edition: "2021",
clippy_lints: "none",
no_stdlibs: true,
lints: "none",
srcs: ["src/lib.rs"],
rustlibs: [
"libprofcollect_libflags_rust",
],
}
Also add a set of test input to be used in the unit tests for a more
coherent test strategy. A follow-up CL will migrate the code in
commands.rs, codegen_java.rs and codegen_cpp.rs.
