devel/py-yaml: Move py-pyyaml To match upstream naming  move py-yaml to py-pyyaml  https://wiki.freebsd.org/Python/PortsPolicy#Naming Requested by: koobs (python) Reviewed_by: ??? Differential_Revision: D23803
Rebuild all updated ports.
~1500 ports need built to test this but it did at least get past poudriere dep. checks.
From a technical standpoint this looks good.
From a practical standpoint I wonder if this change is worth the churn. This would mean pkg install py36-yaml wouldn't work anymore? The port name has been around for 17 years, it's not hard to imagine there's tooling and muscle memory built up around it.
Conversely, there will have and continue to be users that pkg install 'pyyaml' using the name referenced by upstream and in all current and future documentation, and the names used by all packages that depend on it, that dont/cant find it.
pyyaml and python-dateutil are one of the very few outstanding incorrectly named python packages in the tree preventing us from getting to a better place in python port packaging regarding calling things exactly what they're called
