* Apply patch for PR 41056 (19954) to fix chunk
  filter. Now flushes work better.

* Protect against any sort of non-block read that
  would block. If ap_get_brigade() shows that, return
  EAGAIN.

* Further refinement for PR41056 / PR 19954 (mostly-fixed in r480135.)
  We assume that a successful read but an empty brigade
  is NOT cause for EAGAIN. Testing may or may not
  confirm this assumption, in which case that test
  may be required as well.

* If no data is available at this point of time we need to switch into the
  BODY_CHUNK_PART state like we do several lines later in the code in the
  same situation.

* Case statements should go on their own line.  (No functional change.)

* modules/http/http_filters.c
  (ap_http_filter): Put case on its own line.

* Add missing Changelog entry for PR41056 / PR 19954. This was fixed in r480135.

* Detabify and make spacing in HTML code the same as before r593816. This
  avoids that the autoindex test (t/modules/autoindex) fails. Adjusting
  the autoindex test would cause it to fail with older versions and would
  make it harder to recognize regressions.

Prevent 1-byte overflow on 8192 boundary (see PR 43310)


Alternate fix... profiling indicates that the string
termination is completely unneeded and superflous. In
which case, the original allocation size is sufficient
since nothing external worries about a NULL nor
looks for it.

* Add the novary flag to RewriteCond in order to prevent the appending
