Use more-specific value for X-Object-Manifest header.

When uploading a large image to Swift, the segments are named
glance/<imageid>-<segmentnumber>. However, the value of
X-Object-Manifest is only glance/<imageid> without the trailing
dash. This can lead to odd behavior when there are other objects that
start with <imageid>, but are not actually segments of the image.

For example, in bug 1112653, a user was using python-swiftclient to
delete an old, segmented image with id 10. However, they also had an
image with id 100b2316-9187-48d8-b327-dded22d1dc71-00001, and since
"10" is a prefix of "100b2316-9187-48d8-b327-dded22d1dc71-00001",
swiftclient thought that the second image was just another segment of
image 10 and deleted it.

Further, had someone issued a GET request for /glance/10, the
resulting response would have contained the bytes from 10's segments
*plus* the bytes from 100b2316-9187-48d8-b327-dded22d1dc71-00001,
which is definitely not the right behavior.

Obviously, this change doesn't go back and fix up old
manifests. However, it should help prevent this problem from
recurring.

Add migration 19 - move image location data

Migration 19 moves image location data from images.location to
the new image_locations table. The sqlalchemy db driver has been
updated to look at this new table, but the complexity of multiple
locations is not yet exposed to the reset of the system.

Add migration 20 - drop images.location

The image location data has been migrated out of this column, so it
is no longer useful. This migration simply drops it.

Fix migration 015 downgrade with sqlite.

This adds a list() call around the select sqlalchemy to pull
the list of locations that start with swift. The list() call
forces the select query to finish, before we try to update the
database.

Remove unnecessary logging from migration 019

Migration 019 included debug logging for every sqlalchemy call
that was run. This commit removes all of the logging and makes it
consistent with the other migrations.

Avoid using logging in signal handlers

Fixes bug 1029727

It is possible for logging to cause problems during signal handlers.
Fortunately, the logging we have in signal handlers is minimal and does
not add enough value to try to keep through workarounds.
