Informs cockroachdb#22329. This commit adds the max_prepared_transactions session variable, returning a value of math.MaxInt32 to indicate that there is no limit on the number of prepared transactions that can be created. This change has the effect of unblocking the pgjdbc XADataSourceTest test suite, which was previously failing during initialization. Is also includes a small patch to work around cockroachdb#31632 (unsupported deferrable qualifier) so that each test in the XA test suite actually runs (and fails). Release note: None
Informs cockroachdb#22329. This commit adds a new `system.prepared_transactions` table, which will be used to track prepared transactions. The table includes all of the information needed to implement XA two-phase commit transactions, along with additional metadata needed to implement `pg_catalog.pg_prepared_xacts`. Release note: None
Informs cockroachdb#22329. This commit adds new syntax for `PREPARE TRANSACTION <gid>`, `COMMIT PREPARED <gid>`, and `ROLLBACK PREPARED <gid>`, for parity with Postgres support. Handling of the syntax is currently unimplemented. Release note: None
