CHANGELOG.md: reformat for consistency, combine some lines.

Remove "Replacing sed by $(SED) in Makefile ([#8786])" which isn't
user-visiable.

Add `Protocol: Splicing is enabled by default` which didn't get
included because of the missing colon in:

	Changelog-Deprecated Splicing is now enabled by default!

In 9b51d66!
