Stephen Williams bbc80a84a6 Rename $log to $log10.
Verilog-2005 defines the base-10 log function to be $log10. This makes
sense because in C the log() function is the natural log. So add the
$log10 function.

Since there may be legacy code that uses the $log function, leave it
defined, but we should consider at least printing a warning when the
$log function is used.

Stephen Williams f5263c9447 Add the va_math module and constants.vams include file.
The va_math.vpi module implements systen-function versions of the
Verilog-A math functions. This library was contributed by Cary R.

Also add the constants.vams include file. This is pretty much
direct from the Verilog-AMS LRM.
