Move bundled copy of sqlite one level deeper to better separate it
from our patches, READMEs, etc. Also, add a shim header so we can use it for building with system sqlite. TEST=compile BUG=22208 Review URL: http://codereview.chromium.org/3108030 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@56619 0039d316-1c4b-4281-b951-d872f2087c98

-# Summary of tests:
-#
-# speed4p-join1: Join three tables using IPK index.
-# speed4p-join2: Join three tables using an index.
-# speed4p-join3: Join two tables without an index.
-#
-# speed4p-view1: Querying a view.
-# speed4p-table1: Same queries as in speed4p-view1, but run directly against
-# the tables for comparison purposes.
-#
-# speed4p-subselect1: A SELECT statement that uses many sub-queries..
-#
-# speed4p-trigger1: An INSERT statement that fires a trigger.
-# speed4p-trigger2: An UPDATE statement that fires a trigger.
-# speed4p-trigger3: A DELETE statement that fires a trigger.
-# speed4p-notrigger1: Same operation as trigger1, but without the trigger.
-# speed4p-notrigger2: " trigger2 "
-# speed4p-notrigger3: " trigger3 "
-#
-
-# Set up the schema. Each of the tables t1, t2 and t3 contain 50,000 rows.
