ee58c77008 httpd: fix unbounded memory use in eerror handling 
httpd uses recursion for its read loop:

  future<> read() {
     _read_buf.consume().then([] {
        ...
        if more work:
           return read();
     });
  }

However, after error handling was added, it looks like this:

  future<> read() {
     _read_buf.consume().then([] {
        ...
        if more work:
           return read();
     }).rescue(...);
  }

The problem is that rescue() is called for every iteration of the loop,
instead of for the loop in its entirety.  This means that a rescue
continuation is allocated for every processed request, but they will only
be called after the entire loop terminates.  This results in tons of
allocated memory.

Fix by moving error handling to the end of the loop (and incidentally using
do_until() instead of recursion).

2289b03354 httpd: Fix RST handling 
I found wrk sometimes sends RST instead a FIN to close a connection. In
this case, we will reset the connection and go to CLOSED state. However
httpd will not delete this, so we will have leaked connections in CLOSED
state.

Fix by handling the exception and sending an empty response as we do in
EOF case. Here we do not pass the exception to upper layer again,
otherwise httpd will be very noise.
