This series is a follow-up of the following previous series:
https://lists.gnu.org/archive/html/qemu-devel/2020-10/msg02251.html
The 9p patches of the previous series have already been merged.
This series consists of 2 parts:
1. libqos patch 1 removes a limitation of the qtest/libqos subsystem:
support for more than one device using the same (official) QEMU device
name.
Like discussed in the previous series, if nobody finds this patch useful
then just ignore it. I needed it in the previou series before but
eventually decided for a different approach and personally don't need it
in near future.
2. Patches 2 to 5 enhance debugging issues with the qtest framework. I would
appreciate if they got merged, because I still find them useful while
working on new test cases.
Changes of these patches from derived series:
* Squashed previous patches 1 & 2 -> [patch 1].
* Dropped ANSI color escape sequences [patch 3].
* Squashed previous patches 4 & 5 -> [patch 3].
* Extended commit log to provide more details about purpose [patch 4].
