  Rewrite to work for stream connection
  Update Linux version for pktoptions TTL

A copy has to be made of the message as there is
a trace token. There was a bug where the actual
message was incorrectly modified even if it was a
literal.

* sverker/erts/sendfile-error-bug/ERL-784/OTP-15461:
  erts: Fix hanging sendfile bugs when socket closes unexpectedly
  erts: Fix unexpected inet_reply message from failing file:sendfile
  erts: Fix bug in sendfile for active socket

* siri/logger/std-recreate-file-if-rotated/OTP-15469:
  [logger] Re-create log file if deleted

* raimo/test-cuddling:
  Parallel stress test strong_rand_bytes
  Update OS version numbers

This is an update to logger_std_h, which makes it play well with tools
like logrotate.

* siri/logger/refactor-built-in-handlers:
  [logger] Write asynchronously to disk log
  [logger] Add statistics counter for drops due to message bursts
  [logger] Further refactor built-in handlers
  [logger] Move common handler code to logger_h_common

A failing file:sendfile call would often send a message
{inet_reply, Port, {error, Reason}} that would pollute the mailbox
of the calling process.

TCP_REQ_SENDFILE has its own reply messages format
{sendfile, _, _} and does not expect an inet_reply message.

Solution: Suppress inet_reply error message if TCP_ADDF_SENDFILE
is set.

driver_select() was called after port had been killed
by tcp_inet_sendfile() calling tcp_send_error().
