Remove use of queue from remote.c

This removes a use of the queue data structure (common/queue.h) from
remote.c.

The queue is replaced with a std::vector.  A queue was not needed, as
the code never de-queued items.

This removes quite a bit of boilerplate code, mostly involved with
marshalling arguments to be passed through the queue iterator.

Tested by the buildbot.
