When ASAN is enabled, a false buffer overflow warning is raised. It is
a false positive since everything starting at '\0' will get ignored by
the PCMPISTRI instruction (see Intel(r) SSE4 Programming Reference,
5.3.1.5 "Valid/Invalid Override of Comparisons", and 5.3.1.2
"Aggregrate Operation", case "Equal any").
Concerns about reading past the end of the page turns out to be false,
there always seem to be a valid page after the current one (for static
and heap memory at least). It is an non-issue since strlen also does
not have issues with this.
Rather than fully disabling SSE 4.2 and using the fallback
implementation for ASAN-enabled builds, read the set of characters from
'a' into the mask without a 128-bit read and then still use SSE 4.2
for the actual query.

Pull the "cast this to a pointer to an __m128i" idiom into a macro, and
use the macro; have that macro use "const" in the casts.

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.
