wireshark devel 1.99.0

Primarily: Adds a devel option.
Secondary: Makes the URLs canonical; Wireshark have formally
permanently moved the http links to https.
Thirdly: Jiggles the mirrors about a bit; currently both the main url
and the mirror are US based, so for the sake of balance I’ve gone for
one US, one EU, both SSL/TLS. The new mirror link is an official
Wireshark recommended one.
Lastly: Adds a very optional dependency to use our libpcap, if so
desired.
wireshark: update 1.12.2 bottle.
