* windows: Make solana-test-validator work (#20099)
* windows: Make solana-test-validator work
The important changes to get this going on Windows:
* ledger lock needs to be done on a file instead of the directory
* IPC service needs to use the Windows pipe naming scheme
* always disable the JIT
* file logging not possible yet because we can't redirect stderr,
but this will change once env_logger fixes the pipe output target!
* Integrate review feedback

Cross cluster gossip contamination is causing cluster-slots hash map to
contain a lot of bogus values and consume too much memory:
https://github.com/solana-labs/solana/issues/17789
If a node is using the same identity key across clusters, then these
erroneous values might not be filtered out by shred-versions check,
because one of the variants of the contact-info will have matching
shred-version:
https://github.com/solana-labs/solana/issues/17789#issuecomment-896304969
The cluster-slots hash-map is bounded and trimmed at the lower end by
the current root. This commit also discards slots epochs ahead of the
root.

* removes id from push_lowest_slot args (#18645)
push_lowest_slot cannot sign the new crds-value unless the id (pubkey)
argument passed-in is the same pubkey as in ClusterInfo::keypair(), in
which case the id argument is redundant:
https://github.com/solana-labs/solana/blob/bb41cf346/gossip/src/cluster_info.rs#L824-L845
Additionally, the lookup is done with self.id(), but insert is done with
the id argument, which is logically a bug.

The repair-peers cache is reset each time repair service loop runs,
and so computed repeatedly for the same slots:
https://github.com/solana-labs/solana/blob/d2b07dca9/core/src/repair_service.rs#L275
This commit uses an LRU cache to persists repair-peers for each slot.
In addition to LRU eviction rules, in order to avoid re-using outdated
data, each entry also has 10 seconds TTL.

Broadcast stage and retransmit stage should arrange nodes on turbine
broadcast tree in exactly same order. Additionally any changes to this
ordering (e.g. updating how unstaked nodes are handled) requires feature
gating to keep the cluster in sync.
Current implementation is scattered out over several public methods and
exposes too much of implementation details (e.g. usize indices into
peers vector) which makes code changes and checking for feature
activations more difficult.
This commit encapsulates turbine peer computations into a new struct,
and only exposes two public methods, get_broadcast_peer and
get_retransmit_peers, for call-sites.
