C++ style guide.

[Alan Conway <ac...@redhat.com>]

Very belatedly I've put up the Qpid style guide:

http://cwiki.apache.org/confluence/display/qpid/CppStyleGuide

This guide reflects things that were agreed on the list some time ago,
and things that are de facto standard in the existing codebase. The page
includes guidelines for making further style changes which are intended
to promote code consistency and discourage frivolous debate over minor
stylistic issues.

Cheers,
Alan.
