Upgrade our sqlite to 3.6.1, with the local changes made by Gears. I'm

checking in the full sqlite tree to make upstream merges easier.  This means
we'll have generated sources split out from the originals.

One important change this makes is that "BEGIN" now defaults to "BEGIN
IMMEDIATE" rather than "BEGIN DEFERRED".  This doesn't affect us because we
don't use unqualified BEGIN statements.

The full CL is too big for Rietveld.  I'm splitting it into 2.  This one is
reviewable.  The other CL is just a fresh drop of:
