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.

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.
