MINOR: proxy: add setup_new_proxy() function

Browse Source 
Split alloc_new_proxy() in two functions: the preparing part is now
handled by setup_new_proxy() which can be called individually, while
alloc_new_proxy() takes care of allocating a new proxy struct and then
calling setup_new_proxy() with the freshly allocated proxy.
