Add file/line information to procedural warnings and darray fixes
...
When -pfileline=1 is used the queue procedural warnings have file
and line information added to the messages. Also switch the trace
debugging to be off by default.
Also, Add some preliminary missing darray functionality.

Handle case that strings are arguments of functions/tasks.
...
When strings are arguments to functions/tasks, that doesn't suddenly
make them implicitly scalar. Strings are vectors and should be treated
that was, even if they are IMPLICIT_REG.

time. If possible, defer evaluation until run time. If used in a
constant expression, output a "sorry" message.

Fix expression type for compressed assignment statements.
...
A compressed assignment statement should give exactly the same
result as the equivalent uncompressed statement. This means
that the type (signed/unsigned) of the LHS affects the type of
the RHS expression (unlike in normal assignments). We need to
take care that bit/part selects and concatenations are correctly
identified as unsigned values, even in the cases where they
reduce to a single whole signal.
