When compiling a protobuf with gcc 4.1.2 for powerpc, I ran into
another of the following warning message:

INFO: From Compiling my_proto.pb.cc powerpc-603e-linux-gcc:
bazel-out/local_linux-dbg/genfiles/my_proto.pb.cc: In member
   function `virtual void MyProto::Clear()':
   bazel-out/local_linux-dbg/genfiles/my_proto.pb.cc:223: warning: this
      decimal constant is unsigned only in ISO C90

The line in the proto file that was triggering it was:

  if (_has_bits_[24 / 32] & 4278190080) {
    ZR_(field1_, field2_);
  }

_has_bits_ is a uint32.  The constant mask should therefore be
unsigned.  This change updates the constant to be generated as
unsigned.

Conformance tests can now be excluded based on their names.

Migrate writer to printer for C#

Add cmake support.

Change-Id: I121cb70bfdc4894c297ab1a36f1db47736c0652b

Remove Android.mk

This allows us to enable conformance tests even when we know
that some tests are failing and need to be fixed.

Add protoc path detection for Mac OS

This file bares a different copyright license and also doesn't actually
work (out-dated file lists, no config.h/pbconfig.h, refers to inexist
AOSP paths).

Fix two issues on vs2010.

Add remaining not-already-imported well known types files to podspec

Fix unittest in i386

Document why the podspec is on the root of the repo

A few corrections to the proposed podspec

Change the C# enum generator inherit from primitive generator

RepeatedField::begin()/end() will return NULL when the content is empty.
Passing these NULL values to std::copy() will result in runtime complains
from some compilers (e.g., vs2010).

destroy() should always call the destructor because the caller may rely on
the destructor to do clean-ups.

Add oneof support for c#

default configuration. In default configuration, maven needs webdav for
deployment, which cannot be found in central repository.
