* do more validation of imported headers in light client

* generalize informant with traits

* informant implementation for light client

* make comment into TODO

* fix broken test

* disable full checking of headers in light client in sync tests

This is a huge change, which includes some changes to replace code that
originally cloned to reuse allocations instead. The updated
`elastic-array` crate renames its consuming `Vec`-conversion method to
`into_vec`, which means that I can do a simple
`sed -i 's/to_vec/into_vec/'` and then fix the compilation errors.

This commit is probably a minor performance win and definitely a
significant readability win.
