163eb3c56b systemc: Centralize how object parents are chosen.
There's a lot of repeated code for this. Also, the sc_vector type
needs to be able to artificially inject a parent for the objects it
creates.

f7a2c41be0 systemc: Add some error checks to some classes.
These check whether those classes are being constructed in legal
circumstances, and avoids a null pointer dereference.

f9298649bb systemc: Track exports and prim channels, and call their callbacks.
Also call the callbacks on the ports which were already being tracked.

7dd1cea517 systemc: Implement sc_export.
This change ignores the rule that sc_exports all have to be bound
exactly once and only by the end of elaboration. If it's bound more
than once, then the earlier binding will be overwritten, and if it's
not bound at all then it will act like a null pointer. To accomodate
doing those checks in the future, the sc_export_base constructor and
destructor are in the .cc file even though they do very little so that
they can be extended to track a list of all exports which exist.

a60868f5d5 systemc: Seperate the "external" header interface.
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.
