Instead, the DTLS driver can detect these states implicitly based on
when we write flights and when the handshake completes. When we flush a
new flight, the peer has enough information to send their reply, so we
start a timer. When we begin assembling a new flight, we must have
received the final message in the peer's flight. (If there are
asynchronous events between, we may stop the timer later, but we may
freely stop the timer anytime before we next try to read something.)
The only place this fails is if we were the last to write a flight,
we'll have a stray timer. Clear it in a handshake completion hook.

Go 1.9 is slated to have some backwards-incompatible changes to
html/template. See https://github.com/golang/go/issues/19952.
If I'm reading this correctly, the issue is that the context-aware auto
escaper had some magic around the 'html' filter, but it would get
confused if this was used in the wrong context.
This does not apply to us because we never used it in an attribute, etc.
Nonetheless, we can be compatible with it and tidy up markupPipeWords'
type signature. It should have had type template.HTML -> template.HTML,
not string -> template.HTML, because it expects the input to be
pre-escaped. (The old 'html' escaper, in turn, probably should have had
type string -> template.HTML, but I guess it didn't because all this
existed for a text/template migration convenience of some sort?)
I considered adding our own escapeHTML with type string -> template.HTML
and fixing markupPipeWords to be template.HTML -> template.HTML, but
markupPipeWords does not correctly handle all possible template.HTML
input. If a | were in an attribute somewhere, it would mangle the text.
Instead, I kept it of type string -> template.HTML and defined it to
perform the HTML escaping itself. This seems to produce the same output
as before in Go 1.8 and tip.

compilation units because UBSan sometimes explodes. This is nuts, but so
it goes.
Instead, use StackTraits to extract the STACK_OF(T) parameters and
define an iterator type.

This is because we do not want to have any messages that are absorbed

implemented at a higher level. We could limit the number of ClientHello

this fatal behaviour for a long time without issue and it's simple.
