> Subject: git-p4: Add new functions in preparation of usage
Nit: as a convention, you should lowercase the letter after the colon in
the subject. As in "git-p4: add new functions..."
This applies for other patches as well.

Change the self.verbose reference to an optional method parameter. Update the existing references to this function to pass the self.verbose since it is no longer available on "self" since the function is no longer contained on the P4Sync class.
Hmmm, so does the patch before this not actually work since
encodeWithUTF8() isn't defined yet? When you reroll this series, you
should swap the order of the patches since the previous patch depends on
this one, not the other way around.

The return value for both functions is the number of bytes, but the meaning is lost under python3 since the count does not match the number of characters that may have been encoded. Additionally, the return value was never used, so this is removed to avoid future ambiguity.
