Approaching Stable API 1.0 release day 2024 Dec 01

[cathay4t]

Before 2024 Dec 01, I would like to replace netlink-packet-route as 1.0 with stable API.

Tasks:

• All dependent rust-netlink crate should hit 1.0 first.
• Simplify the pub API path by removing pub use crate::link::*.
• Cover ALL netlink attribute supported by Linux 6.5.8 should be supported.
• Use Other(DefaultNla) for future netlink attribute with breaking existing users.
• Replace all Vec<u8> to meanful enum and struct.
• All struct and enum should be non_exhaustive unless exception been approved by PR.
• All netlink attribute should be covered by unit test using netlink packet dump for serialize and deserialize.
• 2 month of testing for 1.0 release candidate.
