Systemc: Port over all of the systemc "datatype" headers.
These are the headers originally written by Accellera with a few
modifications. Most significantly, I went through and mostly (but not
entirely) manually editted them to conform to gem5 style and to be
more self consistent. Second, I resolved some macros which optionally
select features. I removed support for deprecated functions, and
otherwise enabled everything.
The actual implementation behind these headers will also be ported
over, but in a subsequent change.
