Merge bitcoin/bitcoin#29648: Remove libbitcoinconsensus

80f8b92f4f2311b9e9a25361c9dd973244e6f95c remove libbitcoinconsensus (fanquake)

Pull request description:

  This was deprecated in `v27.0`, for removal in `v28.0`. See discussion in PR #29189.

    Concept ACK and light review ACK 80f8b92f4f2311b9e9a25361c9dd973244e6f95c. My only hesitation here is that (afaics?) there's now nothing keeping undesired features like threading or globals from working their way into the interpreter in future commits.

-Shared Libraries
-================
-
-## bitcoinconsensus
-***This library is deprecated and will be removed in v28***
-
-The purpose of this library is to make the verification functionality that is critical to Bitcoin's consensus available to other applications, e.g. to language bindings.
-
-### API
-
-The interface is defined in the C header `bitcoinconsensus.h` located in `src/script/bitcoinconsensus.h`.
-
-#### Version
-
-`bitcoinconsensus_version` returns an `unsigned int` with the API version *(currently `2`)*.
-
-#### Script Validation
-
-`bitcoinconsensus_verify_script`, `bitcoinconsensus_verify_script_with_amount` and `bitcoinconsensus_verify_script_with_spent_outputs` return an `int` with the status of the verification. It will be `1` if the input script correctly spends the previous output `scriptPubKey`.
-
-##### Parameters
-###### bitcoinconsensus_verify_script
-- `const unsigned char *scriptPubKey` - The previous output script that encumbers spending.
-- `unsigned int scriptPubKeyLen` - The number of bytes for the `scriptPubKey`.
-- `const unsigned char *txTo` - The transaction with the input that is spending the previous output.
-- `unsigned int txToLen` - The number of bytes for the `txTo`.
-- `unsigned int nIn` - The index of the input in `txTo` that spends the `scriptPubKey`.
-- `unsigned int flags` - The script validation flags *(see below)*.
-- `bitcoinconsensus_error* err` - Will have the error/success code for the operation *(see below)*.
-
-###### bitcoinconsensus_verify_script_with_amount
-- `const unsigned char *scriptPubKey` - The previous output script that encumbers spending.
-- `unsigned int scriptPubKeyLen` - The number of bytes for the `scriptPubKey`.
-- `int64_t amount` - The amount spent in the input
-- `const unsigned char *txTo` - The transaction with the input that is spending the previous output.
-- `unsigned int txToLen` - The number of bytes for the `txTo`.
-- `unsigned int nIn` - The index of the input in `txTo` that spends the `scriptPubKey`.
-- `unsigned int flags` - The script validation flags *(see below)*.
-- `bitcoinconsensus_error* err` - Will have the error/success code for the operation *(see below)*.
-
-###### bitcoinconsensus_verify_script_with_spent_outputs
-- `const unsigned char *scriptPubKey` - The previous output script that encumbers spending.
-- `unsigned int scriptPubKeyLen` - The number of bytes for the `scriptPubKey`.
-- `int64_t amount` - The amount spent in the input
-- `const unsigned char *txTo` - The transaction with the input that is spending the previous output.
-- `unsigned int txToLen` - The number of bytes for the `txTo`.
-- `UTXO *spentOutputs` - Previous outputs spent in the transaction. `UTXO` is a struct composed by `const unsigned char *scriptPubKey`, `unsigned int scriptPubKeySize` (the number of bytes for the `scriptPubKey`) and `unsigned int value`.
-- `unsigned int spentOutputsLen` - The number of bytes for the `spentOutputs`.
-- `unsigned int nIn` - The index of the input in `txTo` that spends the `scriptPubKey`.
-- `unsigned int flags` - The script validation flags *(see below)*.
-- `bitcoinconsensus_error* err` - Will have the error/success code for the operation *(see below)*.

-- `bitcoinconsensus_ERR_TX_INDEX` - An invalid index for `txTo`
-- `bitcoinconsensus_ERR_TX_SIZE_MISMATCH` - `txToLen` did not match with the size of `txTo`
-- `bitcoinconsensus_ERR_DESERIALIZE` - An error deserializing `txTo`
-- `bitcoinconsensus_ERR_AMOUNT_REQUIRED` - Input amount is required if WITNESS is used
-- `bitcoinconsensus_ERR_INVALID_FLAGS` - Script verification `flags` are invalid (i.e. not part of the libconsensus interface)
-- `bitcoinconsensus_ERR_SPENT_OUTPUTS_REQUIRED` - Spent outputs are required if TAPROOT is used
-- `bitcoinconsensus_ERR_SPENT_OUTPUTS_MISMATCH` - Spent outputs size doesn't match tx inputs size
