Many mailing-lists consider a long Cc list a sign of spam and will either drop the message or mark it for moderation. Because patman automatically invokes get_maintainer.pl the Cc list can expand unexpectedly. Allow the user to specify a limit for the Cc list.

This limit is applied after removing any known bouncing addresses. By default no limit is applied.

Signed-off-by: Chris Packham judge.packham@gmail.com --- I've fallen foul of the u-boot ML Cc limit a few times recently. I'm not sure what the actual limit is so I've left patman's default behaviour unlimited.

Changes in v2: - make default None to allow limit 0 to suppress the list completely
