  lib-fs: Fixed multiple concurrent fs_read_stream() calls

Return a new limit-istream, so each istream can have its own independent
offset.

  Changed paths:
    M src/lib-fs/fs-api.c

  Log Message:
  -----------
  lib-fs: Allow multiple fs_read_stream() calls to seekable istreams.

This fixes for example calling fs_default_copy() for an istream which was
already opened:

Panic: file fs-api.c: line 528 (fs_read_stream): assertion failed: (!file->istream_open)
