Ticket #2386: interpretation of LANG variable needs to be case insensitive.

Browse Source 
On Mac OS X, in the iTerm2, when the LANG variable is set to en_US.utf-8
mcedit specifically does not correctly accept input (every character press
is interpreted as a '.'). However when LANG is set to en_US.UTF-8 mcedit
works correctly (see also http://code.google.com/p/iterm2/issues/detail?id=204).

On Linux, nl_langinfo(CODESET) returns upper case UTF-8 whether the LANG is set
to utf-8 or UTF-8.
On Mac OS X, it returns the same case as the LANG input.

So let tranform result of nl_langinfo(CODESET) to upper case unconditionally.
