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.
