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.
