Thanks, Bram and Andy.
In much the same vein as the config functions discussion, I want to
push data to govim rather than have it pull it (because that involves
a round trip). A call to has("xxx") involves a roundtrip from govim ->
Vim. If this is on a hot path, it gets expensive.
And it's totally unnecessary because the version of Vim will not
change from the start.

That's not something I'm solving for here. I'm only looking to support
tagged versions of Vim/Gvim. Neovim will similarly be tested against
tagged versions, and the checks there will be against the Neovim
version (because that's what the user installs/knows).
For example, I have a minimum required version to use govim of
Vim/Gvim v8.1.1158. In order to take advantage of delta-based updates
(that use listener_add) you need at least v8.1.1512.
