#21991: make headerregistry params property MappingProxyType.

It is unlikely anyone is using the fact that the dictionary returned

#9351: set_defaults on subparser is no longer ignored if set on parent.

Before, if a default was set on the parent parser, any default for that
variable set via set_defaults on a subparser would be ignored.  Now
the subparser set_defaults is honored.
