If there really are no c++ sim_objects in the file, then sim_objects can
be set to [] which it used to default to.
This way, if someone hasn't remembered to update their SConscript files
for the new sim_objects and enums parameters, this will give them some
indication what's wrong, rather than the build just failing later.

This will ensure that the value of USE_SYSTEMC is consistent throughout
the build. It also has the side effect that USE_SYSTEMC can be forced
to a particular value if you're confident you know what you're doing
and want to override these checks.

LLVM on Mac OS up until version 10.0.0 doesn't seem to support the
attribute for weak linking and fails to compile. Additionally, even
the basic example tests fail. Therefore, this change disables systemc
by default on Mac OS until we address these issues.

These versions don't support the std::put_time function. Since versions
of gcc older than 5.0 aren't going to be supported at all in the fairly
near future, this should only be temporary. The number of people using
both systemc and older versions of gcc should be very small, or even
zero.

When the native systemc API support is built in, put the systemc and
systemc.h header files in the include path so they can be used as
normal. We don't want any external systemc headers being included and
getting mixed in with our local ones.

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.

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.

This class is mostly implemented as defined by the spec, except that
it doesn't maintain the module name stack (which doesn't yet exist).
