These statements pulled a bunch of symbols from the std namespace into
the global namespace. This commit removes all of them except for
std::string, which is a bit trickier to remove.

This excludes cygwin and mingw from using the self implemented
functions.

This includes all internal changes from around May 20 to now.

Bazel expects all tests to do this.

General
* License changed from Apache 2.0 to New BSD.
* It is now possible to define custom "options", which are basically
annotations which may be placed on definitions in a .proto file.
For example, you might define a field option called "foo" like so:
import "google/protobuf/descriptor.proto"
extend google.protobuf.FieldOptions {
optional string foo = 12345;
}
Then you annotate a field using the "foo" option:
message MyMessage {
optional int32 some_field = 1 [(foo) = "bar"]
}
The value of this option is then visible via the message's
Descriptor:
const FieldDescriptor* field =
MyMessage::descriptor()->FindFieldByName("some_field");
assert(field->options().GetExtension(foo) == "bar");
This feature has been implemented and tested in C++ and Java.
Other languages may or may not need to do extra work to support
custom options, depending on how they construct descriptors.
C++
* Fixed some GCC warnings that only occur when using -pedantic.
* Improved static initialization code, making ordering more
predictable among other things.
* TextFormat will no longer accept messages which contain multiple
instances of a singular field. Previously, the latter instance
would overwrite the former.
* Now works on systems that don't have hash_map.
Python
* Strings now use the "unicode" type rather than the "str" type.
String fields may still be assigned ASCII "str" values; they will
automatically be converted.
* Adding a property to an object representing a repeated field now
raises an exception. For example:
# No longer works (and never should have).
message.some_repeated_field.foo = 1

protoc
- New flags --encode and --decode can be used to convert between protobuf text
format and binary format from the command-line.
- New flag --descriptor_set_out can be used to write FileDescriptorProtos for
all parsed files directly into a single output file. This is particularly
useful if you wish to parse .proto files from programs written in languages
other than C++: just run protoc as a background process and have it output
a FileDescriptorList, then parse that natively.
C++
- Reflection objects are now per-class rather than per-instance. To make this
possible, the Reflection interface had to be changed such that all methods
take the Message instance as a parameter. This change improves performance
significantly in memory-bandwidth-limited use cases, since it makes the
message objects smaller. Note that source-incompatible interface changes
like this will not be made again after the library leaves beta.
Python
- MergeFrom(message) and CopyFrom(message) are now implemented.
- SerializeToString() raises an exception if the message is missing required
fields.
- Code organization improvements.
- Fixed doc comments for RpcController and RpcChannel, which had somehow been
swapped.
