Introduce contentConfigChecksum in the GitRepository.Status to track the
configurations that affect the content of the artifact. It is used to
detect a change in the configuration that requires rebuilding the whole
artifact. This helps skip the reconciliation early when we find out that
the remote repository has not changed.
Moves fetching the included repositories in reconcileSource() to collect
enough information in reconcileSource() to be able to decide if the full
reconciliation can be skipped. This results in reconcileInclude() to
just copy artifact to the source build directory.
Introduce a gitCheckout() method to perform construction of all the git
checkout options and perform the checkout operation. This helps to
easily perform checkout multiple times when we need it in
reconcileSource(). When we check with the remote repository if there's
an update, and find out that there's no update, we check if any other
configurations that affect the source content has changed, like
includes, ignore rules, etc. If there's a change, we need to perform a
full checkout of the remote repository in order to fetch the complete
source. The git checkout no-op optimization is enabled in this method
based on the presence of an artifact in the storage.
The failure notification handler is modifed to handle the recovery of a
no-op reconcile failure and create a notification message accordingly
with the partial commit.

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.

No-op reconciliations are very inefficient, as they carry out
a full clone operation of the target repository even when
no changes have taken place.
This change will execute a remote-ls operation, and cancel
the clone operation if the remote tip commit is still the same
as the one observed on the last reconcilation. In such cases,
an git.NoChangesError is returned.

go-git: Include the commit message in the returned commit object.
libgit2: Set the URL in the checkout error.
Add new method Commit.ShortMessage() for returning short commit
message.

This commit changes the `gogit` behavior for commit checkouts,
now allowing one to reference to just a commit while omitting any
branch reference. Doing this creates an Artifact with a
`HEAD/<commit>` revision.
If both a `branch` and `commit` are defined, the commit is expected
to exist within the branch. This results in a more efficient clone
of just the target branch, and also makes this change backwards
compatible.

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.

This commit moves the previous `AuthStrategy` wiring to a more generic
`AuthOptions`, breaking free from implementation specific details in
the `git` package.
