2018-07-24systemc: Flesh out the sc_port implementation slightly.Gabe Black
This makes other files compile because it changes the relationship between constructors,etc., slightly.

2018-07-24systemc: Add systemc and systemc.h header files.Gabe Black
These are the header files as defined by the standard, although some predefined channel types and most of the sc_dt namespace have yet to be stubbed out, and so those portions are excluded.

2018-07-24systemc: Seperate the "external" header interface.Gabe Black
Most (but not all) of the SystemC headers are part of the "external" interface that an existing, standard compliant module would include through <systemc.h> or <systemc>. Since those follow slightly different rules (relative includes, no gem5 includes), this change separates them out so that they're easier to identify. Also, this change moves the other files into a "core" subdirectory, with the intention to add a "dt", aka data type, directory some time in the future when those standard defined types are implemented.

2018-07-23systemc: Hook up sc_main.Gabe Black
sc_main is exported as a python method on the SystemC_Kernel class and takes a series of string arguments. The internal c++ implementation converts those arguments into the standard argc and argv and uses them to call the standard SystemC version of that function. A weak SystemC version of sc_main is provided so that systemc will compile with or without a simulation provided version of that function. The weak version just complains and dies.
