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.

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.

dfb1fd9bed Added a workaround for the missing MPL includes in Range. 
This is a temporary workaround until Boost.Range is fixed by:

82703b7c14 Moved input_output_iterator_tag to unit tests. 
The class was not used anywhere else and was an implementation detail.

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.

ce030ab2c3 Add support for modular build structure. (#84) 
* Make the library modular usable.

* Switch to library requirements instead of source. As source puts extra source in install targets.

* Remove not-needed reference to Conversion dependency.

* Add missing b2 testing module import.

* Add requires-b2 check to top-level build file.

* Bump B2 require to 5.2

* Change all <source> references to <library>.

* Update copyright dates.

* Move inter-lib dependencies to a project variable and into the build targets.

* Update build deps.

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.

c2929ea6c6 Updated to use boost/bind/bind.hpp to avoid warnings and compliance with C++20. 
boost/bind.hpp emits warnings about deprecating global placeholder argument
keywords. C++20 removes std::bind1st/bind2nd, so replaced their usage with
boost::bind.

3cc4107d01 Added a test for compatibility of boost::distance between Range and Iterator. 
This functionality is used in core Boost components, so it is preferable
to test it in Boost.Iterator, even if it's already tested in Boost.Range,
to discover problems as early as possible.

The test verifies that boost::distance implemented in Boost.Range can invoke
boost::distance in Boost.Iterator (i.e. the function lookup succeeds).

e16f2de233 Inheriting std::iterator is deprecated in c++17. 
Boost's iterator.hpp is deprecated, too. Therefore get rid of all of that and replace inheritance by lifting std::iterator's members into the derived class.
