replace example with syntax definition
inline health_headers directive parse function

* bugfix: change caddyfile_adapt testcase file from space to tab

* reverseproxy: modify health_header value document as optional and add more test cases

caddyfile: Introduce basic linting and fmt check (#3923)
* caddyfile: Introduce basic linting and fmt check

This will help encourage people to keep their Caddyfiles tidy.

* Remove unrelated tests

I am not sure that testing the output of warnings here is quite the
right idea; these tests are just for syntax and parsing success.

headers: Support default header values in Caddyfile with '?' (#3807)
* 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)

see https://github.com/golang/go/issues/42534

* Refactor and cleanup with improvements

* More specific link

reverseproxy: Restore request's original host and header (fix #3509)
We already restore them within the retry loop, but after successful
proxy we didn't reset them, so as handlers bubble back up, they would
see the values used for proxying.

fastcgi: Make sure splitPos handles empty SplitPath correctly (#3491)
In commit f2ce81c, support for multiple path splitters was added. The
type of SplitPath changed from string to []string, and splitPos was
changed to loop through all values in SplitPath.

Before that commit, if SplitPath was empty, strings.Index returned 0 and
PATH_INFO was set correctly in buildEnv.

Currently, however, splitPos returns -1 for empty values of SplitPath,
behaving as if a split position could not be found at all. PATH_INFO is
then never set in buildEnv and remains empty.

Restore the old behaviour by explicitly checking whether SplitPath is
empty and returning 0 in splitPos.

Closes #3490
