erikcorry@google.com 547cbf9da6 Add some support for the code-point code-unit distinction.
Adds String.fromCodeUnits and String.codeUnitAt, and modifies
String.fromCodePoints and String.codePointAt to actually use code points.
Fixes String.charCodes to use code points and adds String.codeUnits.
Reenables some tests, and adds new ones for non-BMP characters.
Fixes issues 6418, 6501 and 1357.

asiva@google.com ebbb7c4134 - Represent strings internally in UTF-16 format, this makes it
compatible with webkit and will allow for easy externalization of
  strings. One byte strings are retained for pure ASCII strings.
  (The language specification was changed recently to reflect this as
   follows "A string is a sequence of UTF-16 code units").
- Remove four byte string class and all references to it.
- Rename some of the string functions in Dart API to make them
  consistent and better describe the underlying functionality
  Dart_NewString => Dart_NewStringFromCString
  Dart_NewString8 => Dart_NewStringFromUTF8
  Dart_NewString16 => Dart_NewStringFromUTF16
  Dart_NewString32 => Dart_NewStringFromUTF32
  Dart_NewExternalString8 => Dart_NewExternalUTF8String
  Dart_NewExternalString16 => Dart_NewExternalUTF16String
  Dart_NewExternalString32 => Dart_NewExternalUTF32String
  Dart_StringGet8 => Dart_StringToUTF8
  Dart_StringGet16 => Dart_StringToUTF16
  Dart_StringToCString => Dart_StringToCString
  Dart_IsString8 => Removed
  Dart_IsString16 -> Removed
  Dart_StringToBytes -> Removed
  Dart_StringGet32 -> Removed

cshapiro@google.com 9aca46d2a7 Implement support for reading and writing UTF-8 encoded strings.
In the past, characters in C strings were assumed to encode themselves
and when converting Dart strings to C strings characters were narrowed
to 8-bit values.

With this change, C strings are assumed to be UTF-8 encoded.
Converting a C string to a Dart string applies UTF-8 decoding and
converting a Dart string to a C string applies UTF-8 encoding.

Also part of this change are new methods to construct uninitialized
string objects and to copy string data.
