Introduce concrete and partial commits. Concrete commits have all the
information from remote including the hash and commit content. Partial
commits are based on locally available copy of a repo, they may only
contain the commit hash and reference.
IsConcreteCommit() can be used to find out if a given commit is based on
local information or full remote repo information.
Update go-git and libgit2 branch/tag clone optimization to return a
partial commit and no error.
Update and simplify the go-git and libgit2 tests for the same.

This commit refactors the previous `Commit` interface into a
standardised `Commit` struct. This object contains sufficient
information for referencing, observating and (PGP) verification.
- `libgit2` commit checkout does now return `HEAD/<SHA1>` as
the branch is not taken into account.
- `git2go` objects are now properly `Free`d everywhere
- `Verify` logic is tested.
