Merge from vendor branch TNF:
Importing p5 package for Net::OAuth-0.19 into net/p5-Net-OAuth as
dependency for scheduled update of net/p5-Net-Twitter to 3.05003.

OAuth is

"An open protocol to allow secure API authentication in a simple and
standard method from desktop and web applications."

In practical terms, OAuth is a mechanism for a Consumer to request protected
resources from a Service Provider on behalf of a user.

Net::OAuth provides:

    * classes that encapsulate OAuth messages (requests and responses)
    * message signing
    * message serialization and parsing.
    * 2-legged requests (aka. tokenless requests, aka. consumer requests)

Net::OAuth does not provide:

    * Consumer or Service Provider encapsulation
    * token/nonce/key storage/management

Please refer to the OAuth spec: http://oauth.net/documentation/spec
