I don't see any other "quic." prefs, should this just go in net.?

e.g. "net.quic_allowed" ?

Net doesn't do any command line parsing, to let it be configured on a
per-URLRequestContext basis, and net can't depend on prefs.

There are plenty of quic constants in hrome_switches.h.

I meant, not in net/, but just have the pref be prefixed by "net." -- just like
the surrounding prefs here.

+1 to a common prefix.

Done.
