Google Music: playback stops at the end of a song with 'gnutls_handshake() failed: An unexpected TLS packet was received.'

[tizonia]

Description

This is a follow-up on the investigation started in #489.

This is a new issue that appears to be originated in the lower layers of the application, either libcurl, or GnuTLS:

libcurl : [SSL re-using session ID
libcurl : [gnutls_handshake() failed: An unexpected TLS packet was received.
libcurl : [stopped the pause stream!
libcurl : [Closing connection 28

I have discussed this issue in the curl-library mailing list:
https://curl.haxx.se/mail/lib-2018-06/0035.html
https://curl.haxx.se/mail/lib-2018-06/0038.html
https://curl.haxx.se/mail/lib-2018-06/0045.html

It looks like the only way out for now will be to implement some mechanism in Tizonia to automatically produce an internal EOS when the 'gnu_tls' error is detected.

Steps to Reproduce

1. Use some Google Music search option.
2. Leave it running alone for a good 20 or 30 songs.
3. At some point, playback stops at the end of a song, and the next song is not played back.

Expected behavior:
Playback does not stop.

Actual behaviour:
The playback stops, although it can be resumed by pressing 'n' or 'p.

Reproduces how often:

Often after 20-30 songs. It has been seen with Raspbian and Ubuntu 18.04 amd64 bintray debs.
