"--dependency_manifest_out=FILE", protoc will write dependencies of
input proto files into FILE. In FILE, the format will be
<full path to FILE>: <full path to 1st proto>\\\n <full path to 2nd proto> ...
This cl is based on https://github.com/google/protobuf/pull/178

Use --manifest-file=somefile.d to output the dependency manifest.
This file will contain a list of files which were read by protoc as part
of creating the output files.  It doesn't include the plugin inputs if
plugins are used, that could be a later extension.
The manifest file is in the format <output file>: <input files>.  The
manifest file format only allows you to specify one output file, which
isn't a problem as it's used to detect input changes in order to detect
when to rerun the protoc command.  The output file used in the manifest
is the manifest filename itself; to use this in ninja you should declare
the manifest file as the first output as well as the depfile input.

Support for maps in the MRI C Ruby extension.

Include names.h as java_names.h in the opensource tree

This adds the Map container and support for parsing and serializing maps
in the protobuf wire format (as defined by the C++ implementation, with
MapEntry submessages in a repeated field). JSON map
serialization/parsing are not yet supported as these will require some
changes to upb as well.

Update python version / setuptools instructions

 Add __version__

Improved little endian byte order detection

Reflect the change that protobuf should now only be supporting 2.6+ (I'd guess note python 3.x+ when its supported in implementation)

Refer to the Python Packaging User Guide for installing setuptools (and pip) instead of out of date telecommunity guide.

Including <sys/param.h> on Mac/iOS doesn't define __BYTE_ORDER so
PROTOBUF_LITTLE_ENDIAN was never being defined. This commit adds a check
for the __LITTLE_ENDIAN__ macro which is defined by clang and Apple gcc on
little endian architectures.

Support Ruby code generation only for proto3.

Update Ruby build setup to produce gems successfully. Include upb as a single .c / .h file.

system. The Ruby module build now uses an amalgamated distribution of
upb, and successfully builds a Ruby gem called 'google-protobuf' with
module 'google/protobuf'.

Source code refactoring. Extracted common functionality in cpp_helpers.c...

Returned print_indent and print_outdent back to printservicestub and printserviceclass in python generator

Make C++ code generation of string oneof field compatible with C++11
