libevhtp: 1.2.10 -> 1.2.11
Package for certificate-transparency
This adds openssl support to libevent. Libevent can be compiled without
openssl, in which case it just doesn't build the libevent_openssl
library. However it seems simpler just to default to including openssl
support.
This bumps evhtp's version because 1.2.11 provides pkg-config
information which makes building certificate-transparency easier.
This has been tested with `doCheck = true;`.
