Add strncpyW to unicode.h

[Jeff Latimer]

I have just been reading the lists and realise that strncpyW/strncpy is 
bad news for some reason.  Please consider this patch withdrawn. 

Wouldn't it be better to implement strncpyW as a wrapper for memcpy?  
Given that all the other string functions are implemeted with the (W) 
version, having strncpyW missing is a bit confusing.
