Java's ScriptEnging is used to transform design doc JS objects into
valid JSON. A custom CouchDbConnector has been implemented to handle
this transformation and create the design docs in the database at
startup.

Priortizing v3 caused problems for v2 clients on POST requests.

This decouples type identifiers used in CouchDB from Java type names.

The creation of new documents is blocked if an empty _rev is set.

Ektorp is introduced as a replacement for CouchDB4J.

Functions need to be stringified to create valid JSON which is accepted
by CouchDB.

Additionally, removed obsolete TODO comment.

The use of a proxy is no longer necessary with AspectJ.

AspectJ fixes

See merge request !67

Use AspectJ weaving instead of JDK/cglib proxies for AOP

See merge request !66

Daniel Gerhardt authored 7 years ago and Daniel Gerhardt committed 7 years ago

This eliminates issues in edge cases like calling annotated methods from
inside the same class. The use of `AopContext.currentProxy()` and the
`exposeProxy` setting are no longer necessary for these cases.

See merge request !65

Scheduling was disabled unintentionally with the config migration in
commit 2ecbfec8.

Annotations are added as a replacement for <task:annotation-driven />.

See merge request !64

Also block local access using IPv6

See merge request !63

Rename CI repository variable for GitLab 9.0+

saved in the session.

This improves/fixes compatibility with third-party OAuth APIs.

Improve handling of context path prefix
