a7907ede7a *: remove fail field from TxnState (#8712)
Originally, `fail` is added to simplify error handling, avoiding large changes on
the Txn() interface API. But it turns out that `fail` becomes the root of many bugs.
So this commit remove the `fail` and make an API refactory.

3742a0d602 *: Txn() function signature refactor and remove ActivePendingTxn() (#8327)
* change Txn() function signature to Txn(active bool)
* ActivePendingTxn() is not used any more because Txn() does the work
* change executor builder getStartTS() uint64 to getStartTS() (uint64, error)

32b1dbd8d5 *: rename "github.com/pkg/errors" to "github.com/pingcap/errors" (#8136)
We import "github.com/pkg/errors" in the code, and actually put
the "github.com/pingcap/errors" there in the vendor path.
That's a dirty hack, and prevent the introduce of Go module.
