* Use client certs in QUIC to get peer's stake
* fixes to cert processing
* integrate the code
* clippy
* more cleanup
* sort cargo deps
* test fixes
* info -> debug
* Minor refactoring of client RpcProgramAccountsConfig handling
* Enable explicit base58/base64 encoding of Memcmp filters, including client backward compatibility with nodes on old software
* Deprecate Memcmp::Encoding
* Remove deprecation warnings in rpc
* Remove deprecation warnings in cli
* Update docs
* Make variants self-documenting
* Remove UseQuic type
Move to storing the UdpSocket on ConnectionCache and accepting a bool
* Remove use_quic from ConnectionCache constructor
Replace with separate with_udp constructor to force callers to choose
* Connection pool in connection cache and handle connection errors
1. The connection not has a pool of connections per address, configurable, default 4
2. The connections per address share a lazy initialized endpoint
3. Handle connection issues better, avoid race conditions
4. Various log improvement for help debug connection issues

separated durable nonce and blockhash domains, which will stop double
execution going forward. However it is possible that a durable
transaction has *already* been executed once as a normal transaction and
it is now a valid durable transaction. #25744 cannot stop such
transactions to be re-executed until the nonce accounts are advanced.
This commit adds a new nonce version indicating that the nonce is moved
out of the blockhash domain, and permanently disables durable
transactions for legacy nonces which are in the blockhash domain.
* client: Remove static connection cache, plumb it instead
* Add TpuClient::new_with_connection_cache to not break downstream
* Refactor get_connection and RwLock into ConnectionCache
* Fix merge conflicts from new async TpuClient
* Remove `ConnectionCache::set_use_quic`
* Move DEFAULT_TPU_USE_QUIC to client, use ConnectionCache::default()
AdvanceNonceAccount instruction updates nonce to blockhash. This makes it
possible that a durable transaction is executed twice both as a normal
transaction and a nonce transaction if it uses blockhash (as opposed to nonce)
for its recent_blockhash field.
The commit prevents this double execution by separating nonce and blockhash
domains; when advancing nonce account, blockhash is hashed with a fixed string.
As a result a blockhash cannot be a valid nonce value; and if transaction was
once executed as a normal transaction it cannot be re-executed as a durable
transaction again and vice-versa.
* Spawn QUIC server to receive forwarded txs
* Update validator port range
* forward votes using UDP
* no forwarding from unstaked nodes
* forwarding stats in banking stage
* fix test builds
* fix lifetime of forward sender
1. Move logics related to creating endpoint, creating new connection and retry 0rtt connections into a wrapper construct QuicNewConnection to put the logic together.
2. get_or_add_connection: logic is much simplified to allow manage the connection cache -- the QUIC connection is lazy constructed. get_or_add_connection should no longer be a global hotspot.
3. Per connection stats update is moved out of get_or_add_connection to avoid bad connection impacting good connections.
