This CL adds the "parcelable_messages" option. When enabled, all
generated message classes will conform to the Android Parcelable
contract. This is achieved by introducing a new parent class for
generated classes which implements the required functionality.
Since the store_unknown_fields option also makes use of a superclass,
ExtendableMessageNano, we have two versions of the new Parcelable
superclass: one extending MessageNano, and one extending
ExtendableMessageNano. These classes are otherwise identical.
As these classes depend on Android framework jars, they are not
included in the host .jar build of the nanoproto library.
Finally, add a test suite for running tests of Android-specific
functionality, as this cannot be done on a desktop JVM.

Nano proto compiler normally throws an error if any service is
defined. If --ignore-services=true is set, no error is thrown and the
service is simply skipped.

So we don't need to keep all option in a single line in the .mk files.

The option is only called 'generate_equals' because:
- equals() is the main thing; hashCode() is there only to
complement equals();
- it's shorter;
- toString() should not be included in this option because
it's more for debugging and it's more likely to stop
ProGuard from working well.
Also shortened the "has bit" expression; was
((bitField & mask) == mask), now ((bitField & mask) != 0).
Both the Java code and the bytecode are slightly shorter.

This option generates fields as reference types, and serializes
based on nullness.

enum_style = c | java: 'c' to put the enum member int constants
at the parent scope; 'java' to create uninstantiatable shell
classes at the parent scope and put the int constants inside.
optional_field_style = default | accessors: 'default' to create
one public mutable field per optional proto field; 'accessors'
to encapsulate the generated fields behind get, set, has and
clear accessors.
This CL only contains parsing code for these two parameters.

- File class name is defined as the java_outer_classname option value
or the file name ToCamelCase; never the single message's ClassName.
- File-scope enums are translated to constants in the file class,
regardless of java_multiple_files.
- If java_multiple_files=true, and file's class name equals a message's
class name, no error. This is done by detecting that the outer class
is not needed and skipping the outer class codegen and clash checks.
Note: there is a disparity between java[lite] and the previous
java{micr|nan}o: when generating code for a single-message proto, the
outer class is omitted by java{micr|nan}o if the file does not have
java_outer_classname. This change makes java{micr|nan}o align with
java[lite] codegen and create the outer class, but will print some
info to warn of potential change of code.
- Also fixed the "is_own_file" detection and made all parseX() methods
static. Previously, all messages in a java_multiple_files=true file
are (incorrectly) considered to be in their own files, including
nested messages, causing them to become inner classes (instance-
bound) and forcing the parseX() methods to lose the static modifier.
- This change supersedes c/60164 and c/60086, which causes javanano to
put enum values into enum shell classes if java_multiple_files=true.
We now always use the parent class to host the enum values. A future
change will add a command line option to provide more flexibility.
- Elaborated in java/README.txt.

If has is set, also always serialize.

Imported source files may have different values for the 'java_multiple_files'
option to the main source file's. Whether the fully qualified Java name of an
entity should include the outer class name depends on the flag value in the
file defining the referenced entity, not the main file. This CL loads the
flag values from the main and all transitively imported files into the params,
and generates the fully qualified Java names accordingly.
If the generator option 'java_multiple_files' is set, its value overrides any
in-file values in all source/imported files. This is because this generator
option is typically used on either none or all source files.

You can use the processor option store_unknown_fields to switch
this support on:
aprotoc --javanano_out=store_unknown_fields=true:/tmp/out
A separate option for extensions isn't required. Support
for unknown fields must be turned on to allow storing and
retrieving extensions, because they are just stored as
unknown fields. If unknown fields are switched on, extension
related code will be generated when a proto message includes
an extension range, or an extension is encountered.
By default, store_unknown_fields is false. No additional
code is generated, and the generator will error out if protos
contain extension ranges or extensions.

Like micro protobufs except:
- No setter/getter/hazzer functions.
- Has state is not available. Outputs all fields != their default.
- CodedInputStream can only take byte[] (not InputStream).
- Repeated fields are in arrays, not ArrayList or Vector.
- Unset messages/groups are null, not "defaultInstance()".
- Required fields are always serialized.
To use:
- Link libprotobuf-java-2.3.0-nano runtime.
- Use LOCAL_PROTOC_OPTIMIZE_TYPE := nano
