rclone now supports symlinks (in experimental)

[Drew Parsons <dparsons@debian.org>]

I've updated rclone to v1.47.

This version is particularly interesting since it now supports symlinks 
(since v1.46).

I upgraded a handful of dependencies along the way to get a successful 
build, uploaded to experimental.  I haven't uploaded rclone itself yet 
since golang-github-koofr-go-httpclient and 
golang-github-koofr-go-koofrclient are now waiting in the NEW queue.  
All packages involved are pushed to experimental branches in the salsa 
repos:
  golang-github-koofr-go-koofrclient
  golang-github-koofr-go-httpclient
  golang-github-abbot-go-http-auth
  golang-github-dropbox-dropbox-sdk-go-unofficial
  golang-github-ncw-swift
  golang-google-api
  rclone


I disabled new dlna server support by listing cmd/serve/dlna under 
Files-Excluded in debian/copyright and using debian/watch (uscan by way 
of gbp) to repackage without the directory. My go-fu was not strong 
enough to disable with a simple patch in the code (when I tried it kept 
giving errors).  dlna can be reinstated once golang-github-anacrolix-dms 
is packaged.

I upgraded golang-google-api to v0.1.0.  v0.4.0 is actually available 
now, but rclone lists v0.1.0 in its go.cmd and I didn't want trouble 
with possible API breakage.


If you're an rclone user then please [build,] test and review.
