Part 1 of refactoring template files into ./contrib

BROKEN without later parts (documentation and Makefile updates)

This commit moves and deletes a lot of Xula2 and SP605 files around.

It also includes a large cleanup of xilinx.mk

+requests from AJ:
+    anything related to not rebuilding all the coregen when not necessary.
+
+    e.g. want a make clean equivalent to removing the build dir but not the
+    cores. This should actually be the default behavior, with different
+    operator for nixing the cores.
+
+    not auto rebuilding the cores when switching branches/commits if not
+    strictly necessary. Because git touches all the files, this may be
+    difficult.
+
+    make isim/simulate will run to completion even if there were errors on
+    the build.
+
+    In the case of make isim, isim will load and run the previously valid
+    simulation. Unless you happen to see the error go by in the build log,
+    you will unknowingly be simulating your previous build, whereas your
+    current build failed to compile.
+
+    The solution is to have make simulate begin by deleting the previous
+    simulation executable, so that it must successfully create a new one
+    before loading isim.
+
+Add linting to tests (aka, tb/*_tb.v)
