unicode diacritics support
There have been issues with non-latin1 diacritics and unicode. http://bugzilla.kernel.org/show_bug.cgi?id=7746 Git 759448f459234bfcf34b82471f0dba77a9aca498 `Kernel utf-8 handling' partly resolved it by adding conversion between diacritics and unicode. The patch below goes further by just turning diacritics into unicode, hence providing better future support. The kbd support can be fetched from http://bugzilla.kernel.org/attachment.cgi?id=12313 This was tested in all of latin1, latin9, latin2 and unicode with french and czech dead keys. Turn the kernel accent_table into unicode, and extend ioctls KDGKBDIACR and KDSKBDIACR into their equivalents KDGKBDIACRUC and KDSKBDIACR. New function int conv_uni_to_8bit(u32 uni) for converting unicode into 8bit _input_. No, we don't want to store the translation, as it is potentially sparse and large.
