Allow converting newbytes to python2 str

[adiroiban]

I have a problem with using grp.getgrnam on Py2.7
I found out that it needs str and does not work with bytes.

Not sure where I should report this but maybe the report could help others who bump on this issue.

(Pdb) name
'str2844-cp\u021b'
(Pdb) type(name)
<class 'future.types.newstr.newstr'>

name_encoded = name.encode('utf-8')
(Pdb) type(name_encoded)
<class 'future.types.newbytes.newbytes'>
(Pdb) name_encoded
b'str2844-cp\xc8\x9b'

(Pdb) grp.getgrnam(name_encoded)
*** KeyError: "getgrnam(): name not found: b'str2844-cp\xc8\x9b'"
(Pdb) grp.getgrnam('str2844-cp\xc8\x9b')
grp.struct_group(gr_name='str2844-cp\xc8\x9b', gr_passwd='x', gr_gid=2948, gr_mem=[])

As I workaround I went for

import codecs
name_encoded = codecs.encode(name, 'utf-8')

Thanks!

I think the workaround should be:

from future.utils import native_str
grp.getgrname(native_str('str2844-cp\u021b'))

Thanks for your comment. Please note that I need native_str from name variable / backward ported Unicode.... I don't think that native_str will help here.
