If ExtendableMessageNano doesn't have any unknown fields, trying to
clear an extension by setting it to null would throw an NPE.

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.

This avoids a race-condition when cachedSize is momentarily set to 0
for non-empty messages if multiple threads call getSerializedSize
(e.g. during serialization).
This is a retry of https://android-review.googlesource.com/#/c/88570/.
getSerializedSize() has been kept non-final so that messages generated
with a previous version of the compiler will not break.

Invalid values from the wire are silently ignored.
Unlike full/lite, the invalid values are not stored into the
unknown fields, because there's no way to get them out from
Nano's unknown fields without a matching Extension.
Edited README and slightly moved it towards a standalone
section for Nano, independent of the Micro section.

Special values for float and double make it inaccurate to test the equality with ==.
The main Java library uses the standard Object.equals() implementation for all fields,
which for floating point fields means Float.equals() or Double.equals(). They define
equality as bitwise equality, with all NaN representations normalized to the same bit
sequence (and therefore equal to each other). This test checks that the nano
implementation complies with Object.equals(), so NaN == NaN and +0.0 != -0.0.

- Get rid of TypeLiteral<T>. It was introduced to read the component
type of a List<T> at runtime. But we use arrays everywhere else,
and we can always read the component type of an array type at
runtime.
- Properly read/write "minor" types (e.g. sint32, sfixed32). The old
implementation could only read/write data as the "typical" types
(one per Java type), e.g. java.lang.Integer -> int32, java.lang.Long
-> int64. So if e.g. an extension specifies sfixed32 as the type, it
would be read/written in the totally incompatible int32 format.
- Properly serialize repeated packed fields. The old implementation
doesn't do packed serialization. As an added bonus, and to be more
aligned with the rest of protobuf nano / main, repeated packable
extensions can deserialize both packed and non-packed data.
- Split Extension class into a hierarchy so under typical usage a
large chunk of code dealing with primitive type extensions can be
removed by ProGuard.
