Lars Buitinck 119cc2407f BUG SVMlight loader should check whether n_features is big enough 
scipy.sparse won't complain when it gets a dimensionality that is
too large, causing crashes in estimators.

Fixes #1630.

Lars Buitinck 8a0b317dd1 TST clean up after ourselves in SVMlight test 
As spotted by @yarikoptic in #2553; also, the test was previously not
loading the bzip'd file.

Justin Vincent d420aafb0f TST + PY3 various fixes 
* Little hack in fixes.py that can be removed when NumPy's
  https://github.com/numpy/numpy/issues/3484 is fixed.
* Little cleanup to the fixes implementation.
* Change the numpy workaround and added a test. Fixed some xrange usage.
* Fix the weight boosting test.
* None is not comparable in python3
* Fix a test that depended on dictionary iteration order.
* Python3 removed execfile
* More test fixes.

Fixes #2122.

Fabian Pedregosa 6fd39fbf12 Add support for preference contraints in svmlight format. 
This feature is explained in http://svmlight.joachims.org/ and adds
the ability to control which pairs are considered when dealing with
pairwise loss functions (e.g. for SVMrank).

In order to preserve API compatibility, I return this information (if
present) as a second column to the y vector.

Lars Buitinck e1ba110829 ENH make generated SVMlight files self-describing in a comment 
Comment is *not* used to parse the files, since that would break
compatibility with other tools; it's just there for the user.

Lars Buitinck 2fb124a8d5 API change in SVMlight reader: handle multiple files with svmlight_load_files 
This might not seem as convenient as having svmlight_load_file handle multiple
files itself, but it's much easier to keep consistent and document (!).

Also, removed the buffer_mb parameter, which was unused, and introduced a dtype
parameter to determine the underlying type of the returned sample vectors.
