Allow u16::MAX to be specified for the instruction index. This makes it
possible to specify the current instruction, so it is not necessary to
know the instruction number.
Solang requires a method for verify ed25519 signatures. Add a new
builtin program at address Ed25519SigVerify111111111111111111111111111
which takes any number of ed25519 signature, public key, and message.
If any of the signatures fails to verify, an error is returned.
The changes for the web3.js package will go into another commit, since
the tests test against a released solana node. Adding web3.js ed25519
testing will break CI.

Merge AccountsDb plugin framework to v1.8 (#20518)
Summary of Changes
Create a plugin mechanism in the accounts update path so that accounts data can be streamed out to external data stores (be it Kafka or Postgres). The plugin mechanism allows
Data stores of connection strings/credentials to be configured,
Accounts with patterns to be streamed
PostgreSQL implementation of the streaming for different destination stores to be plugged in.
The code comprises 4 major parts:
accountsdb-plugin-intf: defines the plugin interface which concrete plugin should implement.
accountsdb-plugin-manager: manages the load/unload of plugins and provide interfaces which the validator can notify of accounts update to plugins.
accountsdb-plugin-postgres: the concrete plugin implementation for PostgreSQL
The validator integrations: updated streamed right after snapshot restore and after account update from transaction processing or other real updates.
The plugin is optionally loaded on demand by new validator CLI argument -- there is no impact if the plugin is not loaded.
