Modified the configure script to allow 3rd party libraries to be either installed
by default (requiring --disable) or ignored by default (requiring --enable).
Moved the SRAM library to the "ignored by default" list because it takes so long
to build. Added all of the OSU standard cell libraries (hs/ms/ls each for
12T, 15T, and 18T). Added a straight-through analog pad for high-speed I/O,
especially for the "caravan" analog variant of the "caravel" harness chip.

At a minimum you will want to pass a configure option to declare the location
of the PDK vendor source distribution (which can be obtained separately),
- ./configure --with-[PDK_name]-source=[path]
+ ./configure --enable-[PDK_name]-pdk=[path]
The open_pdks version of the PDK can be built locally within open_pdks without
the need to declare an install target or run "make install". However, it is
recommended to declare a target location and install there, using
- ./configure --with-[PDK_name]-source=[path] --with-[PDK_name]-local-path=[path]
+ ./configure --enable-[PDK_name]-pdk=[path] --with-[PDK_name]-local-path=[path]
followed by "make" and "make install".
