7ea809897d ipn/ipnserver: enable systemd-notify support
Addresses #964

Still to be done:
- Figure out the correct logging lines in util/systemd
- Figure out if we need to slip the systemd.Status function anywhere
  else
- Log util/systemd errors? (most of the errors are of the "you cannot do
  anything about this, but it might be a bad idea to crash the program if
  it errors" kind)

Assistance in getting this over the finish line would help a lot.

aa9d7f4665 tstime: add Parse3339B, for byte slices
Use go4.org/mem for memory safety.
A slight performance hit, but a huge performance win
for clients who start with a []byte.
The perf hit is due largely to the MapHash call, which adds ~25ns.
That is necessary to keep the fast path allocation-free.

tsweb: refactor JSONHandler to take status code from error if it is present (#905)
This change is to make JSONHandler error handling intuitive, as before there would be two sources of HTTP status code when HTTPErrors were generated: one as the first return value of the handler function, and one nested inside the HTTPError. Previously, it took the first return value as the status code, and ignored the code inside the HTTPError. Now, it should expect the first return value to be 0 if there is an error, and it takes the status code of the HTTPError to set as the response code.

6332bc5e08 controlclient: print http errors if result code != 200.
Turns out for the particular error I was chasing, it actually returns
200 and zero data. But this code mirrors the same check in the map
poll, and is the right thing to do in the name of future debugging.

3f4d93feb2 go.mod: bump depaware to get diffs out of -check, again
I had to use

go get -u github.com/tailscale/depaware@e09ee10c18249e4bf198e66bbd47babcd502637a

to force it to the correct version; it kept selecting head~1.

Maybe because the branch is called main instead of master?
Maybe because of some delay?
