Fix IDNtoUnicode and unittest. ...

Fix IDNtoUnicode and unittest. 
  1. Check whether uloc_getdata returns the default locale because an invalid or unsupported (not a part of ICU data file we use) locale is passed.
    
  2. Replace 'se' with 'sv' in IDNToUnicode test and change the corresponding
    test result to true. U+00C4 IS used in Swedish, but the result was set to
    false because the test results were machine generated with the same
    typo ('se' in place of 'sv') under en_US.UTF-8 locale on Linux and
    we ran this test only on Windows with en_US locale.

1st part of patch is by Matthias Reitinger <reimarvin@gmail.com>; 

BUG=1153
TEST=NetUtilTest.IDNToUnicode passes in various locales, C, en_US, en_US.utf8, 
     ja_JP.utf8, sv_SE.utf8, hi_IN.utf8, ru_RU.utf8, fr_CA

Is there a bug on this somewhere?  Seems like it'd be easy to lose...

There's an internal bug filed on that. I'll refile it here.
