Jason A. Donenfeld 3c25e5ec38 internal/syscall/windows/registry: allow for non-null terminated strings
According to MSDN, "If the data has the REG_SZ, REG_MULTI_SZ or
REG_EXPAND_SZ type, this size includes any terminating null character or
characters unless the data was stored without them. [...] If the data
has the REG_SZ, REG_MULTI_SZ or REG_EXPAND_SZ type, the string may not
have been stored with the proper terminating null characters. Therefore,
even if the function returns ERROR_SUCCESS, the application should
ensure that the string is properly terminated before using it;
otherwise, it may overwrite a buffer."

It's therefore dangerous to pass it off unbounded as we do, and in fact
this led to crashes on real systems.
