Start runtime trace aids
...
The runtime is a vvp runtime engine debug aid that allows for
detailed dump into a debug log. The trace is enabled by setting
the VVP_DEBUG variable and activating specific debug messages
in the vvp source.

Variable drivers propogate initial values.
...
Make varable drivers (reg vectors and real) propagate their initial
values using a special init scheduler queue. This causes the net to
be loaded with reasonable initial values.

Fix code generation for real expressions
...
Real value are vector width of 1, fix real literal to reflect this.
fix leaking real registers in code generation for function arguments.
Load of signal should handle conversion from real to vector. Function
arguments, type vector passed a real value, are an example where this
comes up.

Do not process back-slash escapes twice.
...
Backslash-escapes are processed early, during elaboration, so that
escaped characters show up in all places with the calculated value.
This means the $display formatting will get processed strings and
should not process back-slashes again.
