2018-09-05systemc: Implement some basic plumbing in sc_module.hh.Gabe Black
Take care of some low hanging fruit as far as wrapper methods and the sc_bind_proxy class. Change-Id: I7f55a37eeaa82338bd608218c0261fbc39e65fc2 Reviewed-on: https://gem5-review.googlesource.com/11612 Reviewed-by: Gabe Black <gabeblack@google.com> Maintainer: Gabe Black <gabeblack@google.com>
2018-09-05systemc: Implement most of sc_object.Gabe Black
To avoid making it hard to change sc_object's implementation in the future, this change keeps most of the data members out of sc_object and keeps them in a seperate Object which is managed independently but still matches to the sc_objects one to one. This change also moves away from the SystemC/sc_gem5 namespace pair in favor of sc_gem5. Having two namespaces with classes, etc, living in both was complicating things. Having to use a namespace that doesn't fit in one scheme or the other isn't great, but it's the lesser of two evils.

2018-09-05systemc: Get sc_main to work even when dynamically linked.Gabe Black
Unfortunately multiply defined weak symbols don't work like they're supposed to when the different versions are across dynamic linking boundaries. Fortunately, a weak symbol with no definition at all will still consistently evaluate as 0, and a singularly defined weak symbol will still resolve correctly. Instead of relying on a weak version of sc_main being overridden by a strong/non-default definition, this change leaves it as undefined and detects at run time whether the symbol resolves to 0 or to an actual code location.

This patch adds StreamID and SubstreamID to Request.

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.
