This series adds the option to attach gdbserver and valgrind
to the QEMU binary running in qemu_iotests.
It also allows to redirect QEMU binaries output of the python tests
to the stdout, instead of a log file.

Patches 1-6 introduce the -gdb option to both python and bash tests, 
7-10 extend the already existing -valgrind flag to work also on 
python tests, and patch 11 introduces -p to enable logging to stdout.

In particular, patches 1,2,4,8 focus on extending the QMP socket timers
when using gdb/valgrind, otherwise the python tests will fail due to
delays in the QMP responses.

This series is tested on the previous serie
"qemu-iotests: quality of life improvements"
but independent from it, so it can be applied separately.
