    xen: address MISRA C:2012 Rule 4.1
    
    MISRA C:2012 Rule 4.1 has the following headline:
    "Octal and hexadecimal escape sequences shall be terminated."
    
    The string literals modified by this patch contain octal or
    hexadecimal escape sequences that are neither terminated by the
    end of the literal, nor by the beginning of another escape sequence.
    
    Therefore, such unterminated sequences have been split into a
    separate literal as a way to comply with the rule and preserve the
    semantics of the code.
    
    No functional changes.
