Add a .sft file for the system functions.

# This is the system function descriptor table for the
# builtin (system) functions.

Add missing probabilistic functions and compiletf routines. Add the missing probabilistic functions and add compiletf routines for all the functions. The original calltf routines have been modified as appropriate. The base functions are straight copies from the standard. I have visually verified the curves with 5,000 points and they look correct.

$random vpiSysFuncInt
Declare $rtoi in system.sft instead of the sys_funcs table. The sys_funcs table should be left to those functions that are handled internally by the compiler. Really, the internal sys_funcs table is a legacy from the days before the compiler supported system function tables in the .sft format.

[PATCH] Implement System Verilog $urandom and $urandom_range functions. This patch implements the System Verilog $urandom() and $urandom_range() functions. There are no check to verify that $urandom_range is only given unsigned arguments. If you give it a negative value the bit pattern will be interpreted as a unsigned number.

Add $clog2 function. This patch adds the $clog2 system function. It also makes this function work as a constant function. The runtime version still needs to be updated to use an integer based version instead of the current double based method. The double method suffers from rounding errors.

Add $simparam and other fixes. This patch adds $simparam and $simparam$str from Verilog-A. The analog simulator parameters return 0.0 or N/A. The vvp_cpu_wordsize system function has been moved into the $simparam call and is now named CPUWordSize. This patch also starts the factoring of common code in the vpi directory. Some routines were renamed. The priv.c file was renamed to sys_priv.c to match the include file. System functions can now have strings put to their output.

Add the $abstime() system function from VASM-2.3. This patch adds the $abstime() system function from VAM-2.3. It returns the current time as a real value scaled to seconds.
