  Adds --ignore_service nano proto compiler flag

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.

  Don't reset cachedSize to 0 in getSerializedSize

* commit 'ea68d73c08b3b9319faef8ef9cd283e773a6ef20':
  Don't reset cachedSize to 0 in getSerializedSize

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.

* commit 'd6aeae143cde31b79a2d57a3ee0e41d9083d232d':
  Don't serialize required fields whose 'has' flags are unset.

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.
