[PATCH] go: update bindings to compile with notmuch 0.25

[Kamil Klimkiewicz]

Attached is a simple patch that fixes go bindings to compile with
notmuch 0.25. Please note it doesn't change the go API, ie. go methods
*don't* return Status values. I am not sure you also want to break go
API with the update. If you do, I can update the patch to return
go-idiomatic (*Messages, Status) tuple.

The problem we had in the past was getting any kind of review on go
patches. If you can find someone (or someone responds) to review the
patches then I don't mind an API update.

for some reason this patch doesn't apply to current master

it seems like it would be better to check the return value of
notmuch_query_search_threads here, wouldn't it?

Here especially you should check the return value since the API does not
promise anything about the value of count in case of errors.
