fcb710b by Jakub Zawadzki (darkjames@xxxxxxxxxxxx):

    Add sse4.2 optimized function ws_mempbrk_sse42()
    
    In text protocols, like SIP, lot of time is spend guint8_pbrk(),
    assume that text is not binary (no NULs), and use SSE4.2 pcmpistri
    instruction.
    
    Also move & rename guint8_pbrk() from tvbuff.c as _ws_mempbrk.
    
    HAVE_SSE42 must be defined to use _ws_mempbrk_sse42() only activaded for
    Windows currently.
