65cfefaa3c cmd, docker: Updates for infrastructure
These are some changes to the relay pool server, upgrade server, and
crash receiver to run under Kubernetes. It's been in production for a
while.

cmd/strelaysrv, cmd/strelaypoolsrv: Sanitize query strings (fixes #8314) (#8315)
Use the proper encoding function in the relay server when constructing
the URL. In the pool server, parse and re-encode the query values to
sanitize whatever the client sent.

all: Remove usage of deprecated io/ioutil (#7971)
As of Go 1.16 io/ioutil is deprecated. This replaces usage with the
corresponding functions in package os and package io.

all: Truncate some timestamps (fixes #7457) (#7459)
This truncates times meant for API consumption to second precision,
where fractions won't typically matter or add any value. Exception to
this is timestamps on logs and events, and of course I'm not touching
things like file metadata.

I'm not 100% certain this is an exhaustive change, but it's the things I
found by grepping and following the breadcrumbs from lib/api...

I also considered general-but-ugly solutions, like having the API
serializer itself do reflection magic or even regexps on returned
objects, but decided against it because aurgh...

cmd/strelaypoolsrv: Fix relay shuffling (fixes #6936) (#6935)
When cap(permanentRelays) >= len(permanentRelays) + len(knownRelays),

	append(permanentRelays, knownRelays...)

returns a slice of the array underlying permanentRelays. The subsequent
rand.Shuffle then mixes the permanent and known relays. Sequential
requests may cause strelaypoolsrv to forget its permanent relays. Worse,
concurrent requests may cause shuffling of the same slice on multiple
processors concurrently.

all: Store assets as strings (#6611)
Storing assets as []byte requires every compiled-in asset to be copied
into writable memory at program startup. That currently takes up 1.6MB
per syncthing process. Strings stay in the RODATA section and should be
shared between processes running the same binary.

cmd/strelaypoolsrv: Fix race condition in caching (#6496)
Successful LRU cache lookups modify the cache's recency list, so
RWMutex.RLock isn't enough protection.

Secondarily, multiple concurrent lookups with the same key should not
create separate rate limiters, so release the lock only when presence
of the key in the cache has been ascertained.

all: Tweak error creation (#6391)
- In the few places where we wrap errors, use the new Go 1.13 "%w"
  construction instead of %s or %v.

- Where we create errors with constant strings, consistently use
  errors.New and not fmt.Errorf.

- Remove capitalization from errors in the few places where we had that.

all: Update certificate lifetimes (fixes #6036) (#6078)
This adds a certificate lifetime parameter to our certificate generation
and hard codes it to twenty years in some uninteresting places. In the
main binary there are a couple of constants but it results in twenty
years for the device certificate and 820 days for the HTTPS one. 820 is
less than the 825 maximum Apple allows nowadays.

This also means we must be prepared for certificates to expire, so I add
some handling for that and generate a new certificate when needed. For
self signed certificates we regenerate a month ahead of time. For other
certificates we leave well enough alone.

cmd/*, lib/tlsutil: Refactor TLS stuff (fixes #5256) (#5276)
This changes the TLS and certificate handling in a few ways:

- We always use TLS 1.2, both for sync connections (as previously) and
  the GUI/REST/discovery stuff. This is a tightening of the requirements
  on the GUI. AS far as I can tell from caniusethis.com every browser from
  2013 and forward supports TLS 1.2, so I think we should be fine.

- We always greate ECDSA certificates. Previously we'd create
  ECDSA-with-RSA certificates for sync connections and pure RSA
  certificates for the web stuff. The new default is more modern and the
  same everywhere. These certificates are OK in TLS 1.2.

- We use the Go CPU detection stuff to choose the cipher suites to use,
  indirectly. The TLS package uses CPU capabilities probing to select
  either AES-GCM (fast if we have AES-NI) or ChaCha20 (faster if we
  don't). These CPU detection things aren't exported though, so the tlsutil
  package now does a quick TLS handshake with itself as part of init().
  If the chosen cipher suite was AES-GCM we prioritize that, otherwise we
  prefer ChaCha20. Some might call this ugly. I think it's awesome.

cmd/strelaypoolsrv: Return better error codes and messages (#4770)
The current 500 "test failed" looks and sounds like a problem in the
relay pool server, while it actually indicates a problem on the
announcing side. Instead use 400 "connection test failed" to indicate
that the request was bad and what was the test.

ec62888539 lib/connections: Allow on the fly changes to rate limits (fixes #3846)
Also replaces github.com/juju/ratelimit with golang.org/x/time/rate as
the latter supports changing the rate on the fly.
