DDC-1197: Proxies should handle variable argument lists

[doctrinebot]

Jira issue originally created by user @beberlei:

This is a contingency issue for #60

"Fix to allow for proxy generated classes to respect methods in parent which may use func_get_args internally. Previously they would be passed nothing and thus fail. Also reduces need to build up argumentString. "

Could we use an annotation to indicate when a function uses variable arguments and output call_user_func_array only in that case?

Comment created by @Ocramius:

I won't fix this. There are some problems here that are not trivial:

1 - to make proxies always "safe", we would need to use func*get*args in every proxy call
2 - because of (1), performance will GREATLY degrade
3 - because of (1), byref parameter passing will be broken

What we could do is introspecting the contents of methods to look for func*get*args usages (requires introduction of a complex parser).

I am closing this - consider opening an issue at https://github.com/Ocramius/ProxyManager/issues instead, so we can analyze if this logic can be improved for 3.x with the replacement of the "simple" doctrine proxies with something more complete.

Also note that Ocramius/ProxyManager#159 could also solve this without the need for complex logic.
