6beb2e16aa implement remote syslog as a platform feature
To configure, run the following command in an interactive shell (e.g. via
breakglass, or when mounting the permanent partition of the SD card on the
host):

  mkdir /perm/remote_syslog
  echo 10.0.0.76:514 > /perm/remote_syslog/target

I recommend using a (static) IP address for increased reliability, so that
remote syslog works even when DNS does not.

fixes #50

14287515bc dhcp: switch to github.com/rtr7/dhcp4
All existing DHCPv4 packages I looked at were unappealing for one reason or
another, so we’re now using a little helper to glue github.com/google/gopacket
and github.com/mdlayher/raw together, which suffices for our use-case and gives
us more control.

b6086c6f88 reboot: use KexecFileLoad and KEXEC_* from golang.org/x/sys/unix (#42)
The KexecFileLoad syscall wrapper and the KEXEC_* constants were added
to golang.org/x/sys/unix. Use them instead of open-coding them.

24c8ad07b5 streamRequestTo: call f.Sync()
When calling reboot shortly after /update/*, the kernel should flush its cache,
but if you’re not calling reboot, it would be good to persist the data on disk
nevertheless.

c74265523b implement XSRF/CSRF protection for /stop and /restart
While stopping/restarting processes seems like a nuisance at best, it’s good
style to prevent these attacks.

This commit the Double-Submit Cookie protection, which seems appropriate for our
architecture and demands. See also:

4a126f13af init+dhcp changes for Squashfs root file systems
We can do away with a bunch of hacks now, but we’ll keep them around for a
little while to make updates easier (i.e. to boot with old and new gokr-packer
versions, just in case people don’t update both at the same time).

238bbfa55e init: update listeners when pressing <ENTER> on the serial console
This is useful when the network doesn’t come up correctly: you can connect a
network cable between your computer and the gokrazy machine, press <ENTER> on
the serial console and connect to gokrazy via its IPv6 link-local address (to
find the address, use ping6 ff02::1%eth0).

6063608b2b update: introduce a /bootonly handler for bakery
Regular updates hit /boot, /root, then /switch.

bakery only updates /boot, so we need to take care of persisting the active root
partition across /boot updates.

50b9390a43 dhcp: simplify Utsname conversion (#36)
Utsname from golang.org/x/sys/unix contains byte array members instead of
int8/uint8. This allows to simplify the NULL byte indexing in
