A 3-part patchset that (a) improves current RDS-TCP perf

better observability/scaling.

Patch 1 is an enhancment of earlier robustness fixes
that had used separate sockets for client and server endpoints to
resolve race conditions. It is possible to have an equivalent
solution that does not use 2 sockets. The benefit of a
single socket solution is that it results in more predictable
and observable behavior for the underlying TCP pipe of an
RDS connection

Patches 2 and 3 are simple, straightforward perf bug fixes
that align the RDS TCP socket with other parts of the kernel stack.

v2: fix kbuild-test-robot warnings, comments from Sergei Shtylov
and Santosh Shilimkar.
