Removed incorrect optimization of HEAD requests.
The stub status module and ngx_http_send_response() (used by the empty gif
module and the "return" directive) incorrectly assumed that responding
to HEAD requests always results in r->header_only being set. This is not
true, and results in incorrect behaviour, for example, in the following
configuration:
location / {
image_filter size;
return 200 test;
}
Fix is to remove this incorrect micro-optimization from both stub status
module and ngx_http_send_response().
