Amaury Denoyelle b0fe453079 BUG/MINOR: hq-interop: fix FIN transmission
Since the following patch, app_ops layer is now responsible to report
that HTX block was the last transmitted so that FIN STREAM can be set.
This is mandatory to properly support HTTP 1xx interim responses.

  MINOR: qmux: change API for snd_buf FIN transmission

This change was correctly implemented in HTTP/3 code, however an issue
appeared on hq-interop transcoder in case zero-copy DATA transfer is
performed when HTX buffer is swapped. If this occured during the
transfer of the last HTX block, EOM is not detected and thus STREAM FIN
is never set.

Most of the times, QMUX shut callback is called immediately after. This
results in an emission of a RESET_STREAM to the client, which prevents
the data transfer.

To fix this, use the same method as HTTP/3 : HTX EOM flag status is
checked before any transfer, thus preserving it even after a zero-copy.

Criticity of this bug is low as hq-interop is experimental and is mostly
used for interop testing.

This should fix github issue #3038.

This patch must be backported wherever the above one is.
