[PATCH 0/4] odb: support ODB source specific transaction handling

[Justin Tobler <jltobler@gmail.com>]

Greetings,

ODB transactions provide a mechanism for writing new objects in the
repository that are in a pending state until they are committed. With
pluggable ODBs, each source will likely need to handle transactions
differently. This patch series prepares ODB transaction handling to be
defined for each ODB source by creating a generic odb_transaction
structure that stores a callback for committing the transaction.

For now, `struct odb_transaction_loose` is the only transaction
implementation and what is always returned when creating a transaction.
Additionally, this series lifts transaction logic that is common to all
backends out of the implementation layer into
`odb_transaction_{begin,commit}()` layer.

Thanks,
-Justin
