3d29513196 systemc: Implement general and VCD trace support.
This doesn't include WIF trace support, but does make allowances for
adding it in the future.

dfd2e7681e systemc: Fix the default width values for the various sc_trace-s.
These were all set to 8 * sizeof(char) instead of using the size of the
actual data type being traced.

Also add a very simple implementation to the generic sc_signal_in_if<T>
sc_trace which just delegates to the sc_trace of the underlying type T.

3f3773757e systemc: Fortify how exceptions are caught and passed around.
This change tightens up exception catching and makes gem5's systemc
code react to exceptions more in line with the Accellera
implementation. This prevents exceptions from being caught by the
pybind11 integration which makes it very difficult to see where an
exception came from, and makes the output differ by including a
(mostly useless) backtrace.

8f04ccbb0e systemc: Make some functions static in conflict with the spec.
The spec is likely wrong in this case since a lot of the other
neighboring functions are static, and the Accellera implementation and
the tests seem to assume they're static.

a7c7b93971 systemc: Add some non-standard sc_trace variants.
These overloads of sc_trace take the unsigned version of some primitive
types. The compiler thought it was ambiguous how to convert an unsigned
integer value into a signed one since there were several different
functions which took signed integer parameters of various sizes.

These versions of sc_trace aren't in the standard, but they are in the
Accellera implementation and do fix building of the regression tests.

d8a149bb7d systemc: Turn some macros into enums to fix regression test building.
The spec defines these constants to be macros, but the regression test
refers to them using the sc_core namespace. That breaks things because
the macros don't expand to an identifier, they expand to an expression.

This change converts the macros into enums like in the Accellera
implementation to get the regression tests to build.

f8ad69b320 systemc: Fill out some of the sc_vector.hh classes.
The iterator class needs to have some operators, etc., defined so that
tests written against it can compile correctly. The implementations
were heavily influenced by the Accellera implementation.

Also it should be noted that the systemc spec is incorrect where it
defines these classes. When implemented like they are in the
Accellera version, the versions of bind in sc_vector_assembly which
take sc_vector<T>::iterator and iterator parameters are different, and
so they can overload each other. If implemented as described by the
spec however, those types are the same and the code won't compile.
