Fix result_of_is_callable to support references to function pointers.
...
On compilers without the support of expression SFINAE, decltype-based
result_of<FP&(...)> failed to compile (FP is a function pointer type).

Use std::iterator_traits to detect iterators, when possible.
...
This allows next/prior to detect user's iterators that do not
define iterator_category nested type but specialize
std::iterator_traits instead.

Use Boost.Iterator to advance iterators.
...
By using Boost.Iterator we rely on the separate traversal category instead of
the standard iterator category to advance iterators efficiently. For instance,
this allows to advance transform iterators over a random access sequence
in constant time, despite that they are formally input iterators.
Also, std::reverse_iterator formally requires at least bidirectional iterator
as the underlying iterator type. Transform iterators from the example above
don't qualify, so potentially std::reverse_iterator could fail to compile.

Reworked iterator handling in next/prior helpers.
...
The new implementation tries to detect if the incremented/decremented type
is an iterator first and if not falls back to operator probing. This way
iterators that are not SFINAE-friendly (i.e. unconditionally define
arithmetic operators regardless of the iterator category) are still treated
as iterators through std::advance and do not fail the compilation.
The iterator detection is based on probing for the nested iterator_category
type that is expected to be present in class-type iterators. This heuristic
is not flawless since iterators are not required to defined this type.
User-defined iterators may not have it and instead specialize
std::iterator_traits. This use case is not covered by the current implementation
and will likely fail to compile. With C++17 SFINAE-friendly std::iterator_traits
this can be fixed, but currently Boost.Config lacks the macro to detect
availability of this feature. Support for it can be added by a later commit.
Also simplified boost::prior for iterators, removing the possibility of
integer overflow caused by negation of the distance value.
