Compilation errors in is_permutation and callees

[vinnie.falco@…]

The 4-iterator version of is_permutation (in boost/algorithm/cxx14/is_permutation.hpp) has obvious compilation errors:

_ForwardIterator1 is not a type (needless underscore, and a reserved identifier at that)

InputIterator1 is not a type (copy/paste bug?)

iterator_traits is used without namespace qualification in the first two statements.

Furthermore, the functions that it calls are broken in similar ways:

_VSTD namespace qualifier is used, but doesn't exist

etc...

Should already be fixed in develop; see git commit b9d89c559b (svn 84389).
