Rename RowResult to StepResult
...
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.

Merge 'core: wal transaction start' from Pere Diaz Bou
...
This pr adds support for multiple readers and a single writer with a
custom made lock called `LimboRwLock`. Basically there are 5 allowed
read locks which store the max frame allowed in that "snapshot" and any
reader will try to acquire the biggest one possible. Writer will just
try to lock the `write_lock` and if not successful, it will return busy.
The only checkpoint mode supported for now is `PASSIVE` but it should be
trivial to add more modes.
This needs testing, but I will do it in another PR. I just wanted to do
it in another PR.
Closes #544

Add statement interruption support
...
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.
