wip/py-Beaker 1.11.0 NetBSD

Beaker is a web session and general caching library that includes WSGI middleware for use in web applications.

Features: * Fast, robust performance * Multiple reader/single writer lock system to avoid duplicate simultaneous cache creation * Cache back-ends include dbm, file, memory, memcached, and database (Using SQLAlchemy for multiple-db vendor support) * Signed cookie's to prevent session hijacking/spoofing * Cookie-only sessions to remove the need for a db or file backend (ideal for clustered systems) * Extensible Container object to support new back-ends * Cache's can be divided into namespaces (to represent templates, objects, etc.) then keyed for different copies * Create functions for automatic call-backs to create new cache copies after expiration * Fine-grained toggling of back-ends, keys, and expiration per Cache object
