Simplifies the contract for Driver.Stmt.Close in
the process of fixing issue 3865.

Update #4459 (maybe fixes it; uninvestigated)

Tests that here should be automatic retries if a database
driver's connection returns ErrBadConn on Begin. See
"TestTxErrBadConn" in sql_test.go

It was only being used for (*Stmt).Exec, not Query, and not for
the same two methods on *DB.
This unifies (*Stmt).Exec's old inline code into the old
subsetArgs function, renaming it in the process (changing the
old word "subset" to "driver", mostly converted earlier)

To make sure that there is no resource leak,
I suggest to fix the 'fakedb' driver such as it fails when any
Stmt is not closed.
First, add a check in fakeConn.Close().
Then, fix all missing Stmt.Close()/Rows.Close().
I am not sure that the strategy choose in fakeConn.Prepare/prepare* is ok.
The weak point in this patch is the change in Tx.Query:
- Tests pass without this change,
- I found it by manually analyzing the code,
- I just try to make Tx.Query look like DB.Query.

In a transaction, on a Stmt.Query error, it was possible for a
connection to be added to a db's freelist twice. Should use
the local releaseConn function instead.
Thanks to Gwenael Treguier for the failing test.
Also in this CL: propagate driver errors through releaseConn
into *DB.putConn, which conditionally ignores the freelist
addition if the driver signaled ErrBadConn, introduced in a
previous CL.

Higher level tests for the pointer parameters
and scanning, complementing the existing ones
included in the previous CL.
