Add preliminary support for vpiUserSystf, vpi_get_systf_info(), etc.

Browse Source 
This patch changes system tasks and functions to use the vpiUserSystf
property and returns this information when vpi_register_systf() is
called. It also adds the vpiUserDefn property for system tasks and
functions which for now always returns 1 (true). System task and
functions can now get a handle to this information using the
vpiUserSystf property. vpi_systf_info() returns pointers to the
real data so the user will need to be careful when using the pointer
fields (e.g. tfname, user_data, etc.). This is a shallow copy. A deep
copy would require the user to free the various fields and I'm not
certain it is even possible or desirable to copy the user_data for
all cases.

A stub for vpi_compare_objects() was also added since I will need
that when testing the second half of the patch (add iteration over
all the vpiUserSystf objects and add a method to control vpiUserDefn).
