    flask: add const qualifier to security_context_to_sid()
    
    The function does not modify context argument.
    Also it gives more flexibility to this API usage, because some context 
strings
    in Xen are also const char*.
    
    While there,
    - harmonize last parameter's name,
    - u32 -> uint32_t.
