Proposal for actory method for DNS resolvers

[Emmanuel Rodriguez]

Hi,

I implemented a very simple DNS cache for AnyEvent [1] and I have some
troubles creating an original DNS instance the same way as
AnyEvent::DNS does.

It would greatly help me if the code of AnyDNS::resolver() would be
split in two:
 - the resolver singleton call
 - the construction of an instance (factory method)

I create the RT ticket 65250 [2]that proposes a patch but I have a
feeling that RT is not being looked at.

Since I mentioned RT, there's also there another patch that fixes a
bug with weak references that can get undef in the main resolver
instance is destroyed before the callback is called [3].
