Previously this code used the tcpip error space. Since it is no longer part of
netstack, it can use the sentry's error space (except for a few cases where
there is still some shared code. This reduces the number of error space
conversions required for hot Unix socket operations.

This queue only has a single user, so there is no need for it to use an
interface. Merging it into the same package as its sole user allows us to avoid
a circular dependency.
This simplifies the code and should slightly improve performance.
