inets: Patch 1129

    OTP-8739  [httpc] If a request times out (not connect timeout), the
              handler process exited (normal) but neglected to inform
              the manager process. For this reason, the manager did not
              clean up the request table, resulting in a memory leak.
              Also the manager did not create a monitor for the handler,
              so in an unforseen handler crash, this could also create
              a memory leak.

    OTP-8741  The service tftp was spelled wrong in documentation and
              in some parts of the code. It should be tftp.

    OTP-8742  [httpc] Replaced the old http client api module (http) with
              the new, httpc in the users guide.
