Unless err_on_readability is true, we use TEVENT_FD_READ only
to detect errors. Now that we have TEVENT_FD_ERROR we should use it.
As a side effect it makes the code much simpler and clearer, as
we can directly map TEVENT_FD_ERROR to EPIPE.
In addition the err_on_readability=true case is now also
clearer, where we just map TEVENT_FD_READ to EPIPE.

After 12 years we finally got TEVENT_FD_ERROR support :-)
TEVENT_FD_WRITE event handlers never get errors reported
instead the event handler is silently disabled.
There are likely callers relying on that behavior, so
we are not able to chance it.
Now TEVENT_FD_WRITE can be used together with TEVENT_FD_ERROR
in order to get errors reported without waiting for TEVENT_FD_READ.
TEVENT_FD_ERROR can also be used alone in order to detect errors
on sockets in order to cleanup resources.

Backends may require to map individual tevent_fd instances to
a single low level kernel state (e.g. for epoll).
This generic infrastructure adds helper functions using
a generic (sub)part of struct tevent_fd.
The new code will allow us to support more than 2 tevent_fd
instances per fd, which makes sure all backends can provide
a similar behavior. This will be important when we add
TEVENT_FD_ERROR as a 3rd kind of fd event.
The aim is to use this in order to replace the limited implementation
we already have in tevent_epoll.c.
As these helpers are typically called from within
'void tevent_fd_set_flags(struct tevent_fd *fde, uint16_t flags)'
there's no way to report errors. So in order avoid additional
error handling complexity the helpers try to avoid
any allocations which may fail. It also means the logic in
tevent_epoll.c doesn't have to change much.
These are implemented as static line functions in order to avoid
the function call overhead, which showed up in profiles of the
early implementation.

Apart from catching crashes in the actual parsing, we abort if the SD
we end up with will not round trip back through SDDL to an identical
SD.

If a test fails an assertion, and later calls torture_skip() to skip
part of the test, the TORTURE_SKIP result will overwrite the
TORTURE_FAIL result, and the overall outcome will be successful.
To avoid this, we now arrange possible outcomes in order of priority,
and ensure we always keep the higher priority one.
This reveals some failing tests.

If we don't check for NULL after each loop iteration, the failure could
be masked in the next iteration by talloc_asprintf_append() allocating
on the NULL context. That could result in values getting lost.
