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.
