Warning when using boost.range

[madmongo1]

to reproduce:

check out latest develop of boost source tree (currently scheduled for 1.74 release)

$ ./bootstrap.sh
$ ./b2 toolset=clang cxxstd=latest variant=release -j 12 libs/beast//example libs/beast//test

example warning:

The ODEInt library hits this as well. I assume range.hpp is a convenience header; perhaps it can be updated to use the right (non-deprecated) headers.

[jefftrull]

The headers const_reverse_iterator.hpp and reverse_result_iterator.hpp are also getting included, with a deprecation warning.

[jefftrull]

It's in metafunctions.hpp

The fix to this is trivial, and included below. Let me know if you'd prefer a pull request, but this is literally a three line fix. The correct headers are already being included, so the three obsolete ones need merely be removed.

Didn't realize there was an open issue for this or I would have closed this when I fixed it in 486c74fbeba9ee9975e6d68e974230ec8ec22fb0. Closing...
