Merge pull request #3257 from charris/2to3-apply-unicode-fixer

2to3: Apply unicode fixer.
2to3: Stop using 2to3 and remove the tools/py3tool.py file.

The same code base now supports python versions 2.6-2.7 and 3.2-3.3.

Closes #3247.
DOC: Document that the 2to3 fixer is no longer used.
MAINT: Use from future_builtins zip and map.

For Python versions 2.6 and 2.7 the iterator forms of zip and map
can be imported from future_builtins. That is done here so as to
avoid using itertools.{izip, imap}.
ENH: remove obsolete ifort flags, ensure generated binaries work everywhere.

MAINT: Remove unneeded version checks.

Now that only Python versions 2.6-2.7 and 3.2-3.3 are supported
some version checks are no longer needed. This patch removes them
so as to clean up the code.
MAINT: Remove the tools/py3tool.py file.

The tools/py3tool.py file was responsible for running 2to3. Now that
2to3 is no longer run it is not needed and can be removed.
Fix for astype('S') string truncate issue

Calling astype('S') for an array of string objects results in a string array where dtype='S64', even if the original string objects are longer than 64 characters. Add call to GetParamsFromObject() to determine maximum string object length, and use that as string dtype size.
