The docs at os/signal.Notify warn about this signal delivery loss bug at
https://golang.org/pkg/os/signal/#Notify, which says:
Package signal will not block sending to c: the caller must ensure
that c has sufficient buffer space to keep up with the expected signal
rate. For a channel used for notification of just one signal value,
a buffer of size 1 is sufficient.

* fix(caddy): Avoid "operation was canceled" errors
- Also add error handling for StatusGatewayTimeout
* revert(caddy): Revert 504 handling
- This will potentially break load balancing and health checks
* Handle client cancellation as different error

* implement default values for header directive
closes#3804
* remove `set_default` header op and rely on "require" handler instead
This has the following advantages over the previous attempt:
- It does not introduce a new operation for headers, but rather nicely
extends over an existing feature in the header handler.
- It removes the need to specify the header as "deferred" because it is
already implicitely deferred by the use of the require handler. This
should be less confusing to the user.
* add integration test for header directive in caddyfile
* bubble up errors when parsing caddyfile header directive
* don't export unnecessarily and don't canonicalize headers unnecessarily
* fix response headers not passed in blocks
* caddyfile: fix clash when using default header in block
Each header is now set in a separate handler so that it doesn't clash
with other headers set/added/deleted in the same block.
* caddyhttp: New idle_timeout default of 5m
* reverseproxy: fix random hangs on http/2 requests with server push (#3875)

Before, if there was an error in the error handler, we would not write a
status code, which resulted in Go writing a 200 for us by default, which
does not make sense when there's an error. Now we write the second
error's status if available, otherwise 500.
* caddytls: Support multiple issuers
Defaults are Let's Encrypt and ZeroSSL.
There are probably bugs.
* Commit updated integration tests, d'oh
* Update go.mod
* nitpicks and small improvements in basicauth module
1:
roll two if statements into one, since err will be nil in the second case anyhow
2:
unlock cache mutex after reading the key, as this happens by-value and reduces code complexity
3:
switch cache sync.Mutex to sync.RWMutex for better concurrency on cache fast track
* allocate the right kind of mutex
* fileserver: Improve and clarify file hiding logic
* Oops, forgot to run integration tests
* Make this one integration test OS-agnostic
* See if this appeases the Windows gods
* D'oh
Always follow the code path of hashing and comparing a plaintext
password even if the account is not found by the given username; this
ensures that similar CPU cycles are spent for both valid and invalid
usernames.

* Minor cleanup
The server is already added to the context. So, we can simply use that

* Add integration test for auto HTTP->HTTPS redirects
A test like this would have caught the problem in the first place
