Changeset:   912bd521c66a
User:        gustafn
Date:        2019-12-16 11:50:33+00:00
Summary:     - new Tcl API call:

      ns_writer sendfiles /list of filespecs/

   every filespec is a dict which must contain a "filename" element and
   can contain additionally an "-offset" and/or a "-size" element.

      ns_writer submitfiles {{filename /tmp/f1} {filename /tmp/f2 -offset 10}}

   This function is e.g. useful for video streaming applications,
   where multiple video file chunks should be transferred (sometimes)
   concatenated in a single chunk. Therefore, this function avoids the
   necessity to concatenate these files in advance (causing increased
   latency and disk usage).

- extend nsd-internal function NsWriterQueue() by two arguments
  for keeping an optional Ns_FileVec with its length

- extend regression test

- despaghetti code: factor out WriterSetupStreamingMode
  (although being called just once) to improve readability of
  NsWriterQueue()
