Add power operator (**) for real values in a continuous assignment.
...
This patch adds the power operator for real values in a continuous
assignment.

Support delay of user function output
...
When used in continuous assignments, user defined functions may have
delayed output. Handle that by generating the proper .delay node when
needed to delay the output of a .ufunc node.

Net arrays that are addressed are not dangling
...
The nodangle functor tries to delete NetNet objects that are not used.
But NetNet objects that are addressed by a NetArrayDq should never be
dangling. So make sure the NetArrayDq marks the target NetNet correctly.

Fix type handling of real-value system functions in nets
...
In nets, if system functions return a real value the function lookup
was getting the correct width, but was also setting the width to 0,
which confused down-stream net handling. Real-value system fuctions
have a width of 1. (1 real-valued scalar.)

LineInfo uses perm_string for path.
...
Rework the handling of file names to use a perm_string heap to hold
the file names, instead of the custom file name heap in the lexor.
Also rename the get_line to get_fileline to reflect its real duties.
This latter chage touched a lot of files.

Give delay paths scope.
...
Delay paths need a scope. This helps the code generators bind the
modpaths to the correct scope. This patch doesn't actually make use
of the information, it just makes it available to code generators.
