speed improvement by not having to initialize a UNICODE_STRING every time
we make a string comparison. The _RDATA trick allows defining the strings
as const (so we get a SEGV if some code erroneously tries to overwrite
them), while declaring them as non-const in the auto-generated globals.h.
The strings are usually used in NT functions which don't take const
arguments. We avoid a lot of extra casts here...
