don't prepend raw close code anymore

thanks to recent crystal changes adding support for close reasons we
don't need to encode things anymore.

 - Default HEAD request removed has been removed. If you wish to provide it,
   you must give your own handler.
+  - Can not be upstreamed as it would be a breaking change that I did not
+    ask upstream about. This is a very specific issue to the web services I
+    write.
 - Fix to prevent overwriting the `content-length` header value when set by the
   request handler.
+  - Could be upstreamed, as it is a single line fix.
 - Websockets can be closed via an exception, with support for reasons.
+  - Can not be upstreamed. Same reasoning as the first change.
