[webkit-dev] Deprecating features guideline wiki

[Julien Chaffraix]

Hi WebKittens,

following the talk about "Deprecating (web-facing) features and vendor
prefixing" [1], we decided to create a guideline covering new
deprecations or un-prefixing [2]. The rationale is that this will
avoid a lot of the mistakes that we have made in the previous
deprecations and that wisdom could help newcomers understand the pain
points.

The current page is a draft compiled from the meeting notes so any
discussions or editions are welcome!

Thanks,
Julien
