/* Heavily-used const UNICODE_STRINGs are defined here once. The idea is a
speed improvement by not having to initialize a UNICODE_STRING every time
we make a string comparison. The strings are not defined as const,
because the respective NT functions are not taking const arguments
and doing so here results in lots of extra casts for no good reason.
Rather, the strings are placed in the R/O section .rdata, so we get
a SEGV if some code erroneously tries to overwrite these strings. */

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...
Note: The "extern" is required, otherwise either the variables are dropped
entirely, or C++ name mangling is applied despite the extern "C"
bracket, depending on the compiler version */
