Since C++11 range insertion and construction of maps and sets from a
pair of iterators only requires that the iterator's value_type is
convertible to the container's value_type (previously it had to be the
same).

This fixes the implementation to meet that relaxed requirement, by
defining a pair of overloads that either insert or emplace, depending on
the iterator's value_type. Instead of adding yet another overload of
_M_insert_unique and _M_insert_equal, the overloads taking iterators are
renamed to _M_insert_range_unique and _M_insert_range_equal.

The rationale for the fixinclude ioctl macro wrapper is, as far as I can
tell (https://gcc.gnu.org/ml/gcc-patches/2012-09/msg01619.html)

  Fix 2: Add hack for ioctl() on VxWorks.

  ioctl() is supposed to be variadic, but VxWorks only has a three
  argument version with the third argument of type int.  This messes up
  when the third argument is not implicitly convertible to int.  This
  adds a macro which wraps around ioctl() and explicitly casts the third
  argument to an int.  This way, the most common use case of ioctl (with
  a const char * for the third argument) will compile in C++, where
  pointers must be explicitly casted to int.

However, we have existing C++ code that calls the ioctl function via

  ::ioctl(foo, bar, baz)

and obviously this breaks when it gets expanded to

  ::(ioctl)(foo, bar, (int)(baz))

Since the GNU C preprocessor already prevents recursive expansion of
function-like macros, the parentheses around ioctl are unnecessary.

Incidentally, there is also a macro sioIoctl() in the vxworks sioLib.h
header that expands to

  ((pSioChan)->pDrvFuncs->ioctl (pSioChan, cmd, arg))

which also breaks when that gets further expanded to

  ((pSioChan)->pDrvFuncs->(ioctl) (pSioChan, cmd, (int)(arg)))

This patch partly fixes that issue as well, but the third argument to
the pDrvFuncs->ioctl method should be void*, so the cast to (int) is
slightly annoying. Internally, we've simply patched the sioIoctl macro:

  (((pSioChan)->pDrvFuncs->ioctl) (pSioChan, cmd, arg))
