Add a top-level "syncable" feature. (#782) r=ncalexan

* Add a top-level "syncable" feature.

Tested with:

cargo test --all
cargo test --all --no-default-features
cargo build --manifest-path tools/cli/Cargo.toml --no-default-features
cargo run --manifest-path tools/cli/Cargo.toml --no-default-features debugcli

* Add 'syncable' feature to 'db' crate to conditionally derive serialization for Partition*

This is leading up to syncing with partition support.
