Update Gnulib; add new modules; remove `round' module.
This updates Gnulib to v0.0-4951-g6ff7b70. * m4/gnulib-cache.m4: Add floor, ceil, frexp, and ldexp. Add wchar as an explicit dependency; it had been present as an indirect dependency before, but no longer. Remove round, which I had requested earlier, but turned out to be unnecessary.
