  1. DOC: Add curve_fit and changes to fsolve/leastsq to release notes.

    Also add the latter changes to their respective docstrings, and fix some
    asserts in their tests.

  2. BUG: fftpack: use single-precision FFT implementation only for "easy"…

    … sizes
    
    For large "difficult" sizes, the current single precision implementation
    apparently falls back to a non-optimal algorithm, and can produce large
    rounding errors. (bug #1212)
    
    This commit provides a work-around, by enabling the single-precision
    algorithms only for sizes that are composite numbers of 2, 3, and 5, for
    which FFTPACK has explicit support. This is probably a rather
    conservative approach.
