Class initializers prevent ProGuard from inlining any methods
because it thinks the class initializer may have side effects.
This is true for static methods, but instance methods can still
be inlined, because to have an instance you will have touched
the class and any class initializers would have run. But
ProGuard only starts inlining instance methods of classes with
class initializers from v4.11b6, and Android uses v4.4 now.
This change tries to avoid the class initializers as much as
possible, by delaying the initialization of the empty array and
some fields' saved defaults until when they're needed. However,
if the message hosts any extensions, they must be public static
final and therefore introducing the class initializer. In that
case we won't bother with lazy initialization.

For nested message objects, don't generate accessor methods because they have
a default value that is not a valid value (null), so there is no reason to have
get/set/has/clear methods for them. Clients and protos (while serializing) can
check against the invalid value to see if it's been set.

Strip the null elements out before serializing the array.
This is helpful in the cases where the user wants to construct
an array of an inexact size for serialization. For example:
User constructs array of size 5 because they anticipate adding
more than 1 element before serialization. Only 3 get added, so
the array looks like [Obj, Obj, Obj, null, null]. This would
curently crash without this CL.
All repeated fields of ref-type elements can contain null
elements: repeated strings, repeated bytes, and repeated
messages/groups.

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.

Also pre-inlines set() and has() in serialization code. This could
theoretically help ProGuard: the message class size is usually large,
and because of this only, it may refuse to inline an accessor into
the serialization code, and as a result keeps the accessor intact.
Chances are, after pre-inlining all accessor calls within the message
class, those accessors become unused or single-use, so there are more
reasons for ProGuard to inline and then remove them.

- Blank line after opening a message class (but not an enum interface).
- Let all code blocks insert blank lines before themselves. This applies to
'package' statement, all message classes, enum classes or constant groups,
extensions, bitfields, proto fields (one block per field; i.e. accessors
don't have blank lines among them), and basic MessageNano methods. In this
case we don't need to guess what the next block is and create blank lines
for it.
- Fixed some newline/indent errors.
- Only one SuppressWarnings("hiding") per file.

The public doc states that repeated fields are simply concatenated
and doesn't impose a different semantics for packed fields. This
CL fixes this for packed fields and adds tests covering all cases.
Also fixed a bit of missed null-repeated-field treatments.

There's no distinction between a repeated field being null and being
empty. In both cases, nothing is sent on the wire. Clients might for
whatever reason inadvertently set a repeated field to null, so
protect against that and treat it just as if the field was empty.

The field initializers have basically caused the compiled <init> method
to inline the whole clear() method, which means if ProGuard is not used
or failed to inline or remove clear(), there are two big chunks of code
that do the same thing. So why not just call clear() from the ctor.

This CL implements the 'optional_field_style=accessors' option.
All optional fields will now be 1 Java field and 1 bit in a shared
bitfield behind get/set/has/clear accessor methods. The setter
performs null check for reference types (Strings and byte[]s).
Also decentralized the clear code generation.

It didn't appear until API 9 and is thus incompatible with Froyo.
Instead, allocate a new array and System.arraycopy inline.

Prefix access to proto variable names with "this.". Also remove unused
GenerateMergingCode.

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
