ENH: add support for solout in dopri5, dop853
ENH: add solout support for complex ode
STY: docstring style; this is my first commit to branch fetched from another user's scipy fork so it might screw up
STY: change single-line test docstrings to comments
TST: assert -> assert_
MAINT: remove fortran spam in tests
ENH: stats: Add the power_divergence function that generalizes the
chi-squared test statistic, and allow it to be used in chi2_contingency.
Update the interpolative decomposition library to the latest version (attempt two)
MAINT: small changes to variable names and default settings

ENH: linalg: Update the interpolative decomposition library to the latest version
DOC: merge wiki edits for ndimage.  Thanks to Tim Cera.
DOC: merge wiki edits for interpolate module.
DOC: merge wiki edits for stats.mstats module.

Other changes are not mergeable, because they edit docstrings that are
taken over from their non-masked counterparts.

BUG: optimize: fix epsfcn choice in minpack routines

An additional sqrt() was introduced in 703dc23 --- minpack takes the
sqrt internally, so it should not be done again.

The routines can still fail if the problem is badly scaled. The test is
here changed to be less badly scaled.  The correct choice of epsfcn is
problem-dependent and in general needs to be left to the user.

Fixes gh-2639
BUG: interpolate: ensure fitpack work arrays are aligned to double boundaries

gfortran on some optimization levels (-O3) assumes that double-precision
arrays are aligned in memory on sizeof(double) boundaries.

The fitpack_surfit routine failed to properly ensure this, which results
to crashes in some cases.
