This patch changes the base oct to string converter to correctly
pad the top digit. x or xx should display as a single lower case
x when they are located in the top bits. Before these were being
interpreted as 00x or 0xx and displayed X. Also modified the hex
conversion to use this same scheme instead of a loop.
Modified the code that deals with real variables to accept an integer
value when using vpi_put_value(). Also added some type of diagnostic
message for all switch defaults that have an assert(0) to indicate an
error condition, removed CVS comments and removed a small section of
unreachable code.
