Summary: While I should fix the transactional stuff, that patch is going to be
tricky and transactions have some performance implications. This is a simple
fix which prevents the race.
Instead of having the data point at the event ID, have the event point at a
data ID. Insert the data first, then insert the event with the right data
pointer. This is super simple and prevents the race issue.
Test Plan:
- Ran the schema upgrade script, verified that the database was
correctly upgraded. Was also prompted to stop daemons.
- Ran 'repository-launch-master', verified that the discovery daemons were
able to discover new commits and insert events for them. Verified the
committask daemon was consuming events and converting them into tasks.
- Verified new tasks looked correct in the database.
- Browsed web interface.

Summary:
Created a script the runs all the necessary patches for db schema.
Stores information in the db about the latest patch that was applied.
Test Plan:
Created two test files '024.test.sql' and '023.test.sql' in this order.
'023' creates a database and '024' creates a table in this db. First ran
'./upgrade_schema.php 23' and made sure that patches were applied in order.
Then ran './upgrade_schema.php' to make sure db was up-to-date. Checked
manually from the db that the database and table exists.
