[PATCH] xend-config.sxp (-unstable tree)

[aq <aquynh@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 700 bytes --]

This patch (against -unstable ChangeSet@1.1575) does the followings:

- put some configurable variables to xend_config.sxp, and set them to
default values. That will make people aware of their existence, and
let them easily reconfigure xend when needed.
- set some daemon addresses to 'localhost' instead of empty string,
which makes them more secure by default.
- add one comment and fix some wrong comments in XendRoot.py
