9c49d9dc55 pgsql: Move queries to corresponding files 
Aggregate queries in their corresponding files instead of having the
single file for every queries because the database is more complicated.

5d725e67b0 Replace Ancestry with AncestryWithContent struct in database models 
As one of the steps to simplifies the codebase, the AncestryWithContent
struct is renamed to Ancestry, and Ancestry is removed. It will cause
the PostAncestry request to be slower.

ancestry layer. Database is updated to keep the relationship.

ea73aa153d pgsql: searchNotificationLayerIntroducingVulnerability order by layer ID 
This fixes a bug where the API was returning Notification pages ordered
by LDFV.ID instead of by Layer ID.

dpkg.

d4522e9c6e api/v1: indexed layers for notifications 
This change deprecates the old LayersIntroducingVulnerability for a new
one that orders output and contains an Index. This index is not
guaranteed to be consistent across multiple notifications, despite the
current Postgres implementation using the primary key of Layer table.

dc8f71024f pgsql: Reduce cost of GetNotification by 2.5 
By delaying the Layer join to the very end, we can cut the query costs from 540,836 to 219,477.

See Pull Request for details.

5d8336acb3 pgsql: use subquery to plan GetNotification query (#182) 
This change enables the query planner to wait and sort the result set of
our query rather than attempting to re-use the layer table's index for
the ORDER BY clause. Because the result set is always small, this makes
queries that were previous tens of seconds, now tens of milliseconds.

9b191fb598 database: Find the FeatureVersion we try to insert before doing any lock 
This commit is issued in order to limit the bottleneck that the
exclusive database lock on Vulnerability_Affects_FeautreVersion
introduces, when we inserting FeatureVersions. This slowdowns a bit
the FeatureVersion insertion on a mostly empty database but should
increase a lot the throughput and parallelism on a populated database.

06531e01c5 database: disable hash/merge joins in FindLayer 
Our experiments have shown that PostgreSQL 9.4 makes bad
planning decisions about:
- joining the layer tree to feature versions and feature
- joining the feature versions to affected/fixed feature version and vulnerabilities
It would for instance do a merge join between affected feature versions (300 rows, estimated
3000 rows) and fixed in feature version (100k rows). In this case, it is much more
preferred to use a nested loop.
