The logging code that writes out transactions to disk needs to write out
the byte array that we actually use. The code is less hairly without the
generics so drop them.
Move result row to `ProgramState` to mimic what SQLite does where `Vdbe`
struct has a `pResultRow` member. This makes it easier to deal with result
lifetime, but more importantly, eventually lazily parse values at the edges of
the API.
Fixes the following panics:
Benchmarking Execute `SELECT * FROM users LIMIT ?`/Limbo/100: Profiling
for 5.0000 sthread 'main' panicked at core/benches/benchmark.rs:69:43:
called `Result::unwrap()` on an `Err` value: IOError(Os { code: 4, kind:
Interrupted, message: "Interrupted system call" })
note: run with `RUST_BACKTRACE=1` environment variable to display a
backtrace

The name "row result" is confusing because it really *is* a result from
a step() call. The only difference is how a row is represented as we
return from VDBE or from a statement.
Therefore, rename RowResult to StepResult.
This adds an interrupt() method to Statement that allows apps to
interrupt a running statement. Please note that this is different from
`sqlite3_interrupt()` which interrupts all ongoing operations in a
database. Although we want to support that too, per statement interrupt
is much more useful to apps.
