Add ?_cache_size=[..] to connection parameters (#894)
Add a shortcut for PRAGMA cache_size; this is a pretty useful setting:
the default of -2000 (2M) is not especially high, and a lot of people
will probably want to increase this.
For example, while running a bunch of fairy expensive queries in
parallel:
With SetMaxOpenConns(1):
-2000: 5762ms
-20000: 4714ms
With SetMaxOpenConns(20):
-2000: 3067ms
-20000: 2532ms
Which isn't a bad performance boost for changing a single number.
