* Reduce AlltoAll port usage when connecting proxy
Reuse socket ports when connecting proxies in AlltoAll.
Existing port usage in AlltoAll is O(n) for recv and O(n) for send,
reusing socket ports in server or client side will make one of them
O(1), reusing both will reduce the total port usage to O(1) and enables
AlltoAll in >64 MI200 nodes.

Update changelog accordingly.
* Adding the missing roc:: namespace, effectively changing the value of RCCL_LIBRARY from rccl to roc::rccl.
The important difference is that rccl is treated as a symbolic "-lrccl" by linker (and fail the linking
due to a missing library search path), while roc::rccl is a target name, which can resolve into an absolute
library path.
