When calling GitRekt.GitAgent from other nodes, NIF resources might be
garbage collected between two calls:
{:ok, head} = GitRekt.GitAgent.head(agent)
{:ok, commit} = GitRekt.GitAgent.peel(agent, head) #1
{:ok, message} = GitRekt.GitAgent.commit_message(agent, message) #2
In the above example, between #1 and #2 the agent process might garbage
collect the commit. This could lead lead to a bad argument error in #2.
In order to counter this, GitRekt.GiAgent stores a set of borrowed NIF
resources. This way the resources are reference counted and available
between consecutive calls. Note that the references are dropped once a
:DOWN message is received from a given client process.

We want to drop the dependencies to the Git tools. Bindings for libgit2 should be the only thing we need.
For this to happen, we must implement:
upload-packserver side command.receive-packserver side command.Checkout the Packfile transfer protocols documentation.
