MAINT deprecate 1d input arrays for all estimators
...
Passing 1D arrays to check_array, without setting `ensure_2d` to false now
raises a deprecation warning before reshaping it. This will later throw an
error.
All Scaler classes also throw warnings when 1D arrays are passed.
All unit tests/doctests are modified to ensure that no 1D arrays are passed,
except in explicit 1D array tests where the warnings have been silenced.
Additional tests are also included which check for different 1D array cases.
2D array tests with one samples and one features are also added and where
they failed, `check_array` call has been modified to give a more useful error
message

[Feature Selection] Fix SelectFDR thresholding bug ( #2771 )
...
From https://github.com/scikit-learn/scikit-learn/issues/2771 , we were
not correctly scaling the alpha
parameter (http://en.wikipedia.org/wiki/False_discovery_rate#Benjamini.E2.80.93Hochberg_procedure )
with the number of features (== hypothesis). Thus, the alpha
parameter was not invariant wrt the number of features.
The correction is as suggested in the original issue, and a test has
been added that verifies that for various numbers of features, an
appropriate false discovery rate is generated when using the selector.
