Small fix in UEFI and Live
install crop.py
log iso sizes
use 10GB images always

Some LVM tests fail with smaller image sizes. Larger ones don't
really matter as we have sparse files.
fix endless loop if qemu dies *after* saying it will write out a screenshot
fix standstill handing

the handler was in the wrong thread, causing perl to segfault.
Also reduced timeout for standstill.
don't create overly long filenames - with a lot of needles, this can happen
stop waitforneedle early if standstill
fix upload log name
disable excessive debug output
make second stage an important test to be considered for overall result
actually disable the debug output

save backend info in results.json
also serialize the error value into results.json
