Multiple tests were creating the same directory before removing it, making it
possible for concurrent tests to fail because the directory already exists.

stdout can be (and, in automated testing, often is) a host pipe or
similar resource shared between multiple parallel tests, such that it
can become transiently full during testing.

The implementation of O_CLOEXEC is orthogonal to every property tested
by these tests; removing it significantly reduces the number of
redundant tests we run.
Also remove no-op calls to VecCat (calls with a single argument).

Otherwise, C++11-compliant compilers may select PosixErrorOr(const T&)
as the relevant constructor, and fail because std::vector<Mapping> is
not copyable (because Mapping is not copyable).
This is a C++11 defect that is fixed in C++14 (and in C++11 mode for
Clang, but not GCC). See DR 1579,
http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#1579.

netlink_autobind() sets a port id to a process ID, if this address is

Runsc wants to mount /tmp using internal tmpfs implementation for
performance. However, it risks hiding files that may exist under
/tmp in case it's present in the container. Now, it only mounts
over /tmp iff:
- /tmp was not explicitly asked to be mounted
- /tmp is empty
If any of this is not true, then /tmp maps to the container's
image /tmp.
Note: checkpoint doesn't have sentry FS mounted to check if /tmp
is empty. It simply looks for explicit mounts right now.

This option allows multiple sockets to be bound to the same port.
Incoming packets are distributed to sockets using a hash based on source and
destination addresses. This means that all packets from one sender will be
received by the same server socket.

epoll_wait acquires EventPoll.listsMu (in EventPoll.ReadEvents) and
then calls Inotify.Readiness which tries to acquire Inotify.evMu.
getdents acquires Inotify.evMu (in Inotify.queueEvent) and then calls
readyCallback.Callback which tries to acquire EventPoll.listsMu.
The fix is to release Inotify.evMu before calling Queue.Notify. Queue
is thread-safe and doesn't require Inotify.evMu to be held.

We now build all packages (including //test/...) with RBE as part of the Kokoro
presubmit.
The tests do not yet use RBE, because there are some failures. The Golang unit,
integration, and image tests still run locally.
The syscall test suite needs even more work to make it pass on RBE. Those will
be enabled in follow-up CLs. They currently are not enabled at all on Kokoro.
