Use the new array VPI functionality (vpiIndex, vpiParent, vpiArray)
to dynamically generate array word names. The old patch to implement
was mostly reverted.
This patch adds the ability to dump array words. The words are only
dumped if they appear in a $dumpvars() statement (they are not dumped
by default). The name used for the word is <array_name>[<index>], so
you can get unexpected name conflicts.
There is also a slight increase in the memory requirements since each
array word now keeps its own name information. In the future we would
like to change this, but that is a much larger rewrite of the array
code in vvp.
This patch also needs the "Prefix escaped identifier ..." patch to
work correctly (the array word name is an escaped identifier).
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.

Words of net arrays were incorrectly added to the scope. They should
only be attached to the array, and accessed as a word of the array.

more general concept of arrays. The NetMemory and NetEMemory
classes are removed from the ivl core program, and the IVL_LPM_RAM
lpm type is removed from the ivl_target API.
