These C structures have nice Lua bindings.  I believe you can just
for-loop from headers.at[0] up to headers.at[headers.len - 1]
Generally, in almost all cases we use just this auto-mapping between C
and Lua:

(I don't recall if all http headers get always pulled into this
structure, but you should see that practically soon.)
