Use explicit 32-bit integers in random number system functions (issue #661 ).

This simplifies the code by making it independent of the size of 'long', and
fixes the behaviour of urandom_range when the upper limit is > 0x7fffffff.

With a pattern rule, the recipe will only be executed once, even when
the rule has multiple targets. Using this to handle the output from
bison is included as an example in the GNU make manual.
This fixes the makefiles so that bison-generated header files will be
regenerated if they are deleted.

Enable checks for VPI const-correctness.

Note we only want these enabled when building the compiler and runtime
binaries. If we included the ICARUS_VPI_CONST definition in the global

would affect compilation of user VPI code.

Currently $display et al. output nothing when the expression
