ui: add environ property to access os.environ or wsgirequest.environ

The property returns os.environ by default, and is propagted by
ui.copy. During hgweb processing, ui.environ is set to the proper
WSGI-request environment, as contained in wsgirequest.environ. For
CGI, this is the same as os.environ.
