Added nan?, infinite?, degrees->radians, radians->degrees, exact-round, exact-floor, exact-ceiling, exact-truncate to racket/math
...
Altered TR's random arithmetic testing to generate single-flonums and very small flonums; fails now because of erroneous types
Fixes to sgn, sinh, cosh, and tanh:
* preserve single-flonum-ness
* correct zero sign (-0.0) for negative return values that are smaller than epsilon
* correct behavior with NaN and infinite inputs

1d, 2d and 3d function renderers no longer sample outside the function's bounds
...
This makes it more efficient to plot piecewise functions by drawing each piece with one renderer, and possible to plot functions with discontinuities by using a renderer to draw each continuous piece.

Moved some flonum stuff (e.g. flatan2, flnext, +max.0, +min.0, etc.) to unstable/flonum (will document in another commit)
...
Moved Racket-language, doc-generating "defthing" defines to unstable/latent-contract/defthing (will document in another commit)

Plots with intervals too small or too large for flonums (2D and 3D)
...
Bounds fixpoint computation now uses only exact rationals
Speed improvements (3d-plot-area% now uses flonums internally as much as possible)
