Jason A. Donenfeld 39d6e4f2f1 Change queueing drop order and fix memory leaks
If the queues are full, we drop the present packet, which is better for
network traffic flow. Also, we try to fix up the memory leaks with not
putting buffers from our shared pool.

Jason A. Donenfeld 063becdc73 uapi: insert peer version placeholder
While we don't want people to ever use old protocols, people will
complain if the API "changes", so explicitly make the unset protocol
mean the latest, and add a dummy mechanism of specifying the protocol on
a per-peer basis, which we hope nobody actually ever uses.

Jason A. Donenfeld a050431f26 Makefile: export PWD for OpenBSD's ksh(1)
Interestingly, ksh(1) on OpenBSD does not export PWD by default, and it
also has a notion of the "logical cwd" vs the "physical cwd", with the
latter being passed to chdir, but the former being stored in the
non-exported PWD and displayed to the user. This means that if you `cd`
into a directory that's comprised of symlinks, exec'd processes will see
the physical path. Observe:

  # ksh
  # mkdir a
  # ln -s a b
  # cd b
  # pwd
  /root/b
  # ksh -c pwd
  /root/a

The fact of separating physical and logical paths is not too uncommon
for shells (bash does it too), but not exporting PWD is very odd.

Since this is common behavior for many shells, libraries that return the
working directory will do something strange: they `stat(".")` and then
`stat(getenv("PWD"))`, and if these point to the same inode, they roll
with the value of `getenv("PWD")`, or otherwise fallback to asking the
kernel for the cwd.

Since PWD was not exported by ksh(1), Go's dep utility did not understand
it was operating inside of our faked GOPATH and became upset.

This patch works around the whole situation by simply exporting PWD
before executing dep.

Jason A. Donenfeld 5a267f0b8c timers: no need to clear keepalive in persistent keepalive
We do this after sending the keepalive anyway.

This is something of a regression, though, since before we'd cancel and
then send, but now we send and then cancel, so it introduces a potential
race, but hopefully that isn't too big of a deal.

Jason A. Donenfeld 870734ab5e timers: clear send_keepalive timer on sending handshake response
We reorganize this into also doing so on sending keepalives itself,
which means the state machine is much more consistent, even if this was
already implied.
