Fixed "zero size buf" alerts with subrequests.
Since 4611:2b6cb7528409 responses from the gzip static, flv, and mp4 modules
can be used with subrequests, though empty files were not properly handled.
Empty gzipped, flv, and mp4 files thus resulted in "zero size buf in output"
alerts. While valid corresponding files are not expected to be empty, such
files shouldn't result in alerts.
Fix is to set b->sync on such empty subrequest responses, similarly to what
ngx_http_send_special() does.
Additionally, the static module, the ngx_http_send_response() function, and
file cache are modified to do the same instead of not sending the response
body at all in such cases, since not sending the response body at all is
believed to be at least questionable, and might break various filters
which do not expect such behaviour.
