[PATCH/RFC 2/2] lib: string: Make all calls to strnicmp into calls to strncasecmp

[Rasmus Villemoes]

The previous patch made strnicmp into a wrapper for strncasecmp. This
patch makes all in-tree users of strnicmp call strncasecmp directly,
while still making sure that the strnicmp symbol can be used by
out-of-tree modules. It should be considered a temporary hack until
all in-tree callers have been converted.
