2018-10-17dev: Build most of the networking devices in the NULL_ISA build.Gabe Black
The only part of these devices which are incompatible with other ISAs, with the possible exception of endianness transformation, is that the dist_iface implementation refers to ThreadContext methods and that class is heavily tied to the guest ISA. Only those few lines are excluded in a NULL_ISA build.

2018-10-17dev: Build the PCI device models even in NULL_ISA builds.Gabe Black
There are some minor ISA dependencies in the PCI device models, specifically that they use the set<> accessors on the packet objects. This actually compiles fine because the NULL ISA claims to be little endian, but really these accessors should be changed to use little endian all the time since that's what PCI is defined to use, not the guest endianness. The other types of accessors, specifically the ones that default to what the guest wants, should be excluded when building NULL_ISA, and, pending other dependencies, the NULL_ISA should no longer have an endianness associated with it.

2018-10-16systemc: Handle integer based IDs like Accellera does.Gabe Black
This is actually not consistent with how it was handled in 2.0.1 which is supposedly what this is supposed to be backwards compatible with, in that in the earlier version on info and warning messages were suppressed. This is exposed by one of the tests, utils/sc_report/test01, which suppresses an integer ID and then reports an error with it. The "golden" output shows the message supressed, but the actual implementation makes no such distinction. This implementation duplicates Accelleras for now, but a future change will make it consistent with the old implementation so the test will pass.

2018-10-16systemc: Manually correct the golden output for a test.Gabe Black
The golden reference output for the test was to throw an error which is clearly not at all related to the test (it was about immediate self notifications while the test never calls any form of notify()) and which would happen significantly before the end of the test, negating all the other behaviors and checks which would happen after that point. Since it strongly looks like the reference output was updated in error, and because other very similarly structured tests are expected to run silently except for printing "Success" at the end (which it does when run under gem5), this change manually updates the golden reference output to reflect what appears to be correct.

That would result in the exception being injected into the thread twice which is incorrect.
