* uses Option<Slot> for SlotMeta.parent_slot (#21808)
SlotMeta.parent_slot for the head of a detached chain of slots is
unknown and that is indicated by u64::MAX which lacks type-safety:
https://github.com/solana-labs/solana/blob/6c108c8fc/ledger/src/blockstore_meta.rs#L203-L205
The commit changes the type to Option<Slot>. Backward compatibility is
maintained by customizing serde serialize/deserialize implementations.

Add the public facing documentation about the plugin framework: explaining the interface, how to load plugin and the example PostgreSQL plugin implementation.
Updated the rust documentation for the plugin interfaces for accounts and slot.
This changes are targeted for v1.8. Information about transactions will be updated later.
SlotMeta.last_index may be unknown and current code is using u64::MAX to
indicate that:
https://github.com/solana-labs/solana/blob/6c108c8fc/ledger/src/blockstore_meta.rs#L169-L174
This lacks type-safety and can introduce bugs if not always checked for
Several instances of slot_meta.last_index + 1 are also subject to
overflow.
This commit updates the type to Option<u64>. Backward compatibility is
maintained by customizing serde serialize/deserialize implementations.

https://github.com/solana-labs/solana/pull/16646
removed first_coding_index since the field is currently redundant and
always equal to fec_set_index.
However, with upcoming changes to erasure coding schema, this will no
longer be the same as fec_set_index and so requires a separate field to
represent.

- Lets InvokeContext::process_cross_program_instruction() handle the first invocation depth too.
- Marks InvokeContext::verify(), InvokeContext::verify_and_update() and InvokeContext::process_executable_chain() private.
- Renames InvokeContext::process_cross_program_instruction() to InvokeContext::process_instruction().
- Removes InvokeContext::new_mock_with_sysvars().

The solana-program crate can be used in certain embedded environments (HSMs) where
the source of entropy, whether used for cryptographic purposes or not, is tightly
controlled. In these cases, using the default OS source of entrophy is not always
acceptable. Thus, using the default Rust stdlib entropy source for seeding its
default hasher, is prohibited. This means any use of HashMap/HashSet must be able
to be constructed and used with a custom hasher implementation.
This commit removes the use of Itertools::unique() to dedupe Instructions that are
being compiled into a new Message, which uses a default-configured HashMap
under-the-hood. Instead, we use a BTreeSet which does not invoke any entropy
source in order to seed a hash implementation.

Add tests to StakeDelegations and StakeHistory to ensure that the outer
types serialize and deserialize correctly to/from the inner types.
