py3: have bytes version of sys.argv
sys.argv returns unicodes on Python 3. We need a bytes version for us.
There was also a python bug/feature request which wanted then to implement
one. They rejected and it is quoted in one of the comments that we can use
fsencode() to get a bytes version of sys.argv. Though not sure about its
correctness.
Link to the comment: http://bugs.python.org/issue8776#msg217416
After this patch we will have pycompat.sysargv which will return us bytes
version of sys.argv. If this patch goes in, i will like to make transformer
rewrite sys.argv with pycompat.argv because there are lot of occurences.
