1372e9afb6 Fix filter_iterator copy/converting constructor. 
The constructed iterator would have an invalid end iterator because of
a typo in storage initialization.

Fixes https://github.com/boostorg/iterator/issues/92.

1a7996ebd0 Fixed compilation of filter_iterator conversion constructor. 
The constructor would attempt to access a private member of the source
iterator, which could have a different type and therefore have that
member inaccessible. Also, the storage forwarding constructor had incorrect
types used in the forwarding expressions, which caused further compilation
errors.

Fixes https://github.com/boostorg/iterator/issues/90.

a7150173ed Moved shared_container_iterator.hpp in iterator directory, modernized code. 
shared_container_iterator now uses std::shared_ptr to store the reference
to the container. boost::shared_ptr is still supported and is wrapped
into std::shared_ptr on construction, so there is overhead due to allocation
of std::shared_ptr state. Going forward, std::shared_ptr is expected
to be the primary use case. As a bonus, this eliminates the dependency
on Boost.SmartPtr.

Moved shared_container_iterator.hpp into the iterator directory and left
a forwarding header for backward compatibility.

d35869cd25 Moved generator_iterator.hpp in iterator directory and modernized. 
generator_iterator now uses decltype approach to deduce value and reference
types instead of the legacy result_type typedef, which was required to be
defined by the generator function.

The default constructor of generator_iterator now value initializes its
data members to avoid using uninitialized data.

a91fc06bb4 Prohibit default construction of function_output_iterator on function pointers. 
Default-constructed function_output_iterator with function pointers is unusable
and previously would have contained an uninitialized function pointer.
Disable the default constructor using SFINAE to prevent misuse.

Also reformat code.

fd1445140f Removed usage of FunctionTypes in function_input_iterator.hpp. 
This effectively removes usage of MPL in function_input_iterator.hpp and
also simplifies implementation.

8c2fdf6053 Use variadic template expansion in min category deduction in zip_iterator. 
This results in marginally faster compile times in modern code bases
where tuples are variadic.

aadd90df45 Removed direct usage of MPL from zip_iterator.hpp. 
MPL is still used through Boost.Fusion, but that is a matter of
optimizing Boost.Fusion now.

dc57bcf319 Modernized filter_iterator.hpp. 
Use EBO to minimize wasted storage space if the predicate is an empty class.

Disable default constructing non-class predicates using SFINAE instead
of a static_assert. This will help type traits like is_constructible,
when applied to the iterator type.

6e60ea7a88 Extracted and unified default template parameter handling helpers. 
The new eval_if_default helper replaces both ia_dflt_help and
ia_eval_if_default helpers. Additionally, added a new if_default
helper, which expands to the type or the default parameter directly.

The new helpers are placed in separate headers which can be used
without the iterator_adaptor template.

cb81a1dfc3 Extracted enable_if_convertible trait to a separate header. 
Keep including the new header in iterator_adaptor.hpp for backward
compatibility, until downstream users are updated to include the new
header.

dec7d0f24c Extracted min_category as a variadic metafunction. 
The new min_category is similar to minimum_category but accepts variable
number of iterator categories on input instead of just two, and also does
not depend on Boost.MPL for lambda placeholders. The existing minimum_category
trait has been reimplemented in terms of min_category and deprecated.

We don't yet emit deprecation warnings as there is still code that uses
the old trait which we first need to update. Eventually, minimum_category
will emit warnings and will be removed.

f9effffb6d Mostly remove pre-CXX11 workarounds. 
С++03 support was deprecated in 1.85 and now can be removed. This PR clears
many of workarounds, which are no longer needed now.

* Remove unused workaround macros (many of).
* Remove BOOST_STATIC_ASSERT usages.
* Minimize Boost::type_traits dependency (in favour of STL's type_traits).
