http2: fix handling of RST and GOAWAY to recognize partial transfers
- a reset transfer (HTTP/2 RST) did not always lead to the proper
  error message on receiving its response, leading to wrong reports
  of a successful transfer
- test_05_02 was able to trigger this condition with increased transfer
  count. The simulated response errors did not carry a 'Content-Length'
  so only proper RST handling could detect the abort
- When doing such transfers in parallel, a connection could enter the
  state where
  a) it had been closed (GOAWAY received)
  b) the RST had not been "seen" for the transfer yet
  or c) the GOAWAY announced an error and the last successful
  stream id was not checked against ongoing transfers

Closes #10693
