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).

Closes https://github.com/boostorg/iterator/pull/82.

d11499c08c Performance improvement: (#79) 
Performance improvement: Add move semantics to by-value parameters (iterator and predicate), to eliminate the cost of copy-construction. Both the Predicate (Normally a std::function, or lambda), and custom iterators can have state, which can be expensive to copy. Profiler identified this as a bottleneck while using boost::adaptors::filtered.

e8fbd92a61 Use BOOST_STATIC_ASSERT instead of BOOST_MPL_ASSERT (#78) 
The MPL version is slower to compile and `BOOST_STATIC_ASSERT` is
already used in some places. So unify that.

This also fixes `Wzero-as-null-pointer-constant` warnings, see https://github.com/boostorg/mpl/pull/75

7c9b4296a1 Fixed accessing members of the dereferenced value after iterator post-increment. 
The recent commit 5777e9944b broke code such as
(*it++).foo(), where the result of dereferencing would be convertible to
the value type but did not provide the members of the value type. To mitigate
this, return a reference to the value instead of a proxy object. This will only
work for non-writable iterators (and it didn't work for writable iterators
before either) because in that case a proxy is needed to be able to intercept
operator=.

Also fix a similar issue with (it++)->foo() by adding operator-> overloads
to the post-increment result proxies.

Added tests for the fixes.

5777e9944b Added conversion from postfix increment proxy to iterator type. 
This allows expressions such as `Iterator it2(it1++)` to compile.

Additionally separated operations that are allowed on the result of
dereferencing the proxy to a separate set of proxies to make the allowed
set of expressions more strict and unambiguous. In particular, it means
`it++` cannot be converted to value type and `*it++` cannot be converted
to the iterator type anymore. Also, make sure `*it1++ = *it2++` works
as expexted by explicitly converting the proxy to the value type on
assignment.

Fixes https://github.com/boostorg/iterator/issues/75.

853ba3d3c7 Use the proper derived type of the function_input_iterator in iterator_facade. 
This fixes incorrect final iterator type being used in iterator_facade, which
results in an internal base class being returned from various facade methods.
