2018-08-28systemc: Minimally implemented the deprecated sc_simcontext.Gabe Black
This is supposed to be deprecated, but is still used in a small way by the tests. Change-Id: I94fc32f9e0f03d50c00ce5421926203859064020 Reviewed-on: https://gem5-review.googlesource.com/11352 Reviewed-by: Gabe Black <gabeblack@google.com> Maintainer: Gabe Black <gabeblack@google.com>
2018-08-28systemc: Add a minimal version of the deprecated sc_process_b.Gabe Black
This type is deprecated, but some tests still rely on it. This change adds just enough of it to satisfy the tests, and also the several different mechanisms for retrieving the sc_process_b which refers to the currently active process.

This patch adds StreamID and SubstreamID to Request. These fields can be used by a SMMU/IOMMU model to pick up the correct translation context for each request and they correspond to an ASID in a device. For this reason they have been merged together with the request asid in a union, so that a cpu will set the asid and a device will set the Stream and Substream ID.
