varnish and pcre2

[David CARLIER]

Hi,

@Geoff your answer makes sense, so to explain some people start to install
pcre2 over pcre due to pcre's security flaws rather than supposely
performance increases (I do not think there is really). Plus I have
submitted a pcre2 support this week to haproxy which might land in the next
branch. I was just curious how other softwares was doing ;)

Kind regards.
