inets: Patch 1111

    OTP-8508  [httpc] Badly formated error reason for errors occuring
	      during initial connec to a servert. Also, the possible error
	      reasons was not properly documented.

    OTP-8509  [httpd] Issues with ESI erl_script_timeout. </p> *) The
	      "erl_script_timeout" config option is ducumented as a number
	      of seconds. But when parsing the config, in the new format
	      (not a config file), it was handled as if in number of
	      milliseconds. *) When the erl-script-timeout time was
	      exceeded, the server incorrectly marked the answer as sent,
	      thereby leaving client hanging (with an incomplete answer).
	      This has been changed, so that now the socket will be closed.
