int128: optimize and add test cases

For add, the carry only requires checking one of the arguments.
For sub and neg, we can similarly optimize computation of the
carry.

For ge, we can just do lexicographic order.

qemu-iotests: extract wait_until_completed() into iotests.py

The 'drive-mirror' tests often issue 'block-job-complete' and wait for
the QMP completion event. Other types of block jobs also want to wait
for completion but they may not need to issue 'block-job-complete'....

ide-test: fix failure for test_flush

bd07684aacfb61668ae2c25b7dd00b64f3d7c7f3 added a test to ensure BSY
flag is set when a flush request is in flight. It does this by setting
a blkdebug breakpoint on flush_to_os before issuing a CMD_FLUSH_CACHE.
It then resumes CMD_FLUSH_CACHE operation and checks that BSY is unset....

qemu-iotests: make compare_images() common

The iotests.compare_images() function returns True if two image files
have the identical data. Previously this was implemented by converting
images to raw and then comparing their contents using Python. Since
"qemu-img compare" is now available and is more efficient, switch to it....

qemu-iotests: make create_image() common

Both 030 and 041 use create_image(). Move it to iotests.py.

Also drop ImageStreamingTestCase since the class now has no methods.
