Philip Withnall 5e55a4e243 gtlsbackend: Default to indicating no support for DTLS in GTlsBackend ...

I’m unsure what the original reasoning for returning TRUE by default
from supports_dtls was, but it is not backwards-compatible. If a
pre-existing GTlsBackend implementation never implements the
supports_dtls vfunc, the supports_dtls() method will magically return
TRUE rather than FALSE.

Since any backend which does implement DTLS should be implementing the
supports_dtls vfunc (and no DTLS-supporting backends have actually been
merged yet; see bug #697908), it seems safer to make this slight API
break in the name of backwards compatibility than to leave it as
returning TRUE incorrectly.
