Convert EV_SET(2) back into macro again

This change renames function EV_SET to EV_SET_, and calls it from EV_SET().

are always called from userland, i.e., never called from interrupt
context (softint). As a result, we can omit some tedious assertions

Document transition of EV_SET() from a macro to a static inline function

Sponsored by <The NetBSD Foundation>

(kamil)

Convert EV_SET from macro to static __inline function

LLDB introduced support for kevent(2) and it contains the following function:

Status MainLoop::RunImpl::Poll() {
  in_events.resize(loop.m_read_fds.size());
  unsigned i = 0;
  for (auto &fd : loop.m_read_fds)
    EV_SET(&in_events[i++], fd.first, EVFILT_READ, EV_ADD, 0, 0, 0);
  num_events = kevent(loop.m_kqueue, in_events.data(), in_events.size(),
                      out_events, llvm::array_lengthof(out_events), nullptr);
  if (num_events < 0)
    return Status("kevent() failed with error %d\n", num_events);
  return Status();
}

It works on FreeBSD and MacOSX, however it broke on NetBSD.

Culrpit line:
  EV_SET(&in_events[i++], fd.first, EVFILT_READ, EV_ADD, 0, 0, 0);

FreeBSD defined EV_SET() as a macro this way:
#define EV_SET(kevp_, a, b, c, d, e, f) do {    \
        struct kevent *kevp = (kevp_);          \
        (kevp)->ident = (a);                    \
        (kevp)->filter = (b);                  \
        (kevp)->flags = (c);                    \
        (kevp)->fflags = (d);                  \
        (kevp)->data = (e);                    \
        (kevp)->udata = (f);                    \
} while(0)

NetBSD version was different:
#define EV_SET(kevp, a, b, c, d, e, f)                                  \
do {                                                                    \
        (kevp)->ident = (a);                                            \
        (kevp)->filter = (b);                                          \
        (kevp)->flags = (c);                                            \
        (kevp)->fflags = (d);                                          \
        (kevp)->data = (e);                                            \
        (kevp)->udata = (f);                                            \
} while (/* CONSTCOND */ 0)

This resulted in heap damage, as keyp was incremented every time value was
assigned to (keyp)->.

As suggested by Joerg, convert this macro on NetBSD to static __inline
function.

Add a new test case wrap_strip based upon strip (ie: cut&paste.. to start)
but with \ newline line continuations inserted at strange places.

For the shell as it is today, since strip passes, wrap_strip should
automaticallty pass as well (and does), as the \ newline combination
is simply removed, producing identical input to that of strip.

However, for accurate line counting ($LINENO: coming soon) newlines (no
matter the context) cannot simply "go away" - we have to know where they
occur(ed) (perhaps long after the text was read)  so we know what line
number we are actually processing.  This new test case is (perhaps just
part) of future-proofing that the modified code does not break anything.

(kre)

Now that the shell is protecting its internal fds properly, moving
them whenever the user tries to step on one, we can change our behaviour
back to what the kernel considers to be that of a well behaved shell
(wrt file descriptor usage).  If our user causes problems, we will soon
move into recalcitrant process territory, but that should normally be
rare.  This should reduce kernel overheads a little.

(kre)

More DEBUG mode changes.  As usual, read the source if you care.

NFC (normal builds): DEBUG only change - convert parser to newer trace method.
