These warnings were removed when the functionality they warned about
was implemented, but there were some leftovers like unnecessary
includes and some helper functions which hid gem5 specific headers
from the ext directory.

Create and use predefined messages for channels which match the ones
Accellera uses.

Because SC_REPORT_ERROR usually causes an exception to be thrown, it's
easy to assume it will be the last thing executed in a function. It
might, however, be set up to do nothing, in which case the function
will continue to execute.
This change makes sure sc_prim will be set up properly even if errors
about the time a channel can be set up are ignored.
Also, if an exception is thrown while sc_port is being set up, the
corresponding Port object needs to be cleaned up. Rather than try to
intercept exceptions in the constructor and clean up properly, we'll
just make the allocation of the Port object be the last thing it does.
If the function exits early, then the Port pointer will still be
nullptr and nothing will need to be done.

This function requires some slightly annoying bookkeeping since it
doesn't just report whether the current process is running as a result
of a timeout, it reports whether it's running as a result of a timeout
*and* it could have been running from some other sensitivity instead.
Pure timeouts don't count as timeouts which makes it harder to handle
in a general way.

This value is incremented after each delta cycle's evaluate stage and
after timed notifications happen. Its value is used by some channels
to determine whether certain events happened within the previous update
phase to implement the "event()", "posedge()", and "negedge()"
functions.

This change implements channel updates, and also reworks the scheduler
to delegate more to the gem5 event queue by taking advantage of
event priorities to ensure things happen in the right order. There's
a lengthy comment in scheduler.hh describes how that all works.

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.
