Nice!

Nice, so all the old globals are contained in a data struct now...

...which we use during promisor_remote creation now.

Very happy to see this pattern vanquished. ;)

So it's not a "call once, set global state" anymore, but we are also
careful not to trample any existing state on the 'struct repository'.
Nice.

Hm. Am I the only one who doesn't like assigning from the result of an
assignment like this? ...Based on 'git grep "=[^=]\+=[^=]"' yes, I am the
only one :)
Overall this patch looks OK to me, but I see that there are some changes
suggested for the next version, so I'll hold off on a reviewed-by so I
can have a look at those too.
