* ma.masked_equal : force the `fill_value` of the output to `value` (ticket #1253)
* lib._iotools:
- NameValidator : add the `nbfields` optional argument to validate
- add easy_dtype
* lib.io.genfromtxt :
- add the `autostrip` optional argument (ticket #1238)
- use `invalid_raise=True` as default
- use the easy_dtype mechanism (ticket #1252)
