Zachary Anderson 103881d01c Make header include guards great again 
i.e. #ifndef VM_WHATEVER -> #ifndef RUNTIME_VM_WHATEVER

This lets us remove a hack from the PRESUBMIT.py script that existed
for reasons that are no longer valid, and sets us up to add some
presubmit checks for the GN build.

sgjesse@google.com 7fc2230b02 Add support for surrogates when serializing and deserializing for native ports 
As Dart allows creating string with UTF-16 surrogate code units which
are not always in lead/trail pairs, we need to support this in the
communication with native ports.

This change allows surrogate code units in messages to/from native
ports and supports them in the UTF-8 encoding used on the Dart_CObject
structure string representation.

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

cshapiro@google.com dcaf11db96 Implement a heap profiler for the Dart managed heap. 
This profiler will write binary HPROF data to a user provided stream that
can later be viewed by tools such as the Eclipse Memory Analyzer.

While all user defined types are accurately described in the profile data,
internal types that are not self-describing appear as empty objects.  This
will be addressed by a future change.

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.
