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

Support delays for all operators in a continuous assignments.
...
Previously only the logical operators (~, &, |, ^, etc.) supported a
delayed value in a continuous assignment. This patch should extend this
to all operators. An extensive check of real values was done. The same
will be done shortly for bit based nets.
Checks for constructs currently unsupported in continuous assignments
provide a more explicit message (** operator, real user functions,
{!, && and ||} operators with a real argument).

functions that are called from continuous assignments.

Generate explicit locals in the vvp target.
...
With this change, local symbols are not emitted in the vvp target,
but are marked as local. When thus marked, the vvp run time does not
offfer any VPI access and the signals (net or var) are effectively
invisible.

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.

Pass local scope precision from compiler to vvp/etc.
...
This patch adds ivl_scope_time_precision() to the compiler which can
be used to extract the local scope precision. tgt-stub and tgt-vvp
have been modified to use this new function and output a value that
is appropriate. The vvp runtime has been altered to use this new
data which is accessed with the vpip_time_precision_from_handle()
function. vpiTimePrecision uses this function to return the correct
precision.
