Add cat-file example and increase const use in API
This adds an example implementation that emulates git cat-file.
It is a convenient and relatively simple example of getting data
out of a repository.
Implementing this also revealed that there are a number of APIs
that are still not using const pointers to objects that really
ought to be. The main cause of this is that `git_vector_bsearch`
may need to call `git_vector_sort` before doing the search, so a
const pointer to the vector is not allowed. However, for tree
objects, with a little care, we can ensure that the vector of
tree entries is always sorted and allow lookups to take a const
pointer. Also, the missing const in commit objects just looks
like an oversight.
