Add point2<T> alias template for backward compatibility with Boost <=1.68.
Replace multiple point_t aliases of point<ptrdiff_t> with single defined
in point.hpp. The point_t is common used to represent dimensions.
Replace many uses of point<ptrdiff_t> with point_t.
Apply reformatting around point2 changes to respect the line length limit.
Follows up discussion in #154
The point belongs to core basic concepts in GIL, not an optional
utility. The tutorial starts with description of point.
Such core concepts are defined in dedicated headers which is quite
a useful convention that also makes the code structure clearer.
Remove from trivial point2 class superfluous empty destructor,
copy constructor, assignment operator.
Clean up point.hpp formatting (eg. respect line length limit).

For each header, a translation unit is generated along with
corresponding compile target.
Currently, only boost/gil/*.hpp and boost/gil/io/* headres are included.
On CI services, compile self_contained_headers targets only if
TEST_HEADERS environment variable is set. This is to avoid build
timeouts due to CI services limits.
When running b2 locally, the tests are compiled by default.
Group include directives, sort within group:
* In headers of GIL core and extensions:
1. boost/gil/extension/*
2. boost/gil/*
3. boost/*
4. C++ standard library headers
* In programs:
1. boost/gil/*
2. boost/*
3. C++ standard library headers
4. "xxx.hpp" for local headers
Add basic guidelines to CONTRIBUTING.md.
Add/Remove #include <boost/config.hpp> or std headers un/necessary.
Rename gil_concept.hpp to concepts.hpp.
Remove gil_all.hpp - we already have all-in-one boost/gil.hpp.
Tidy up and unify copyright and license header.
Tidy up formatting and excessive whitespaces in some comments.
Remove Doxygen block with file description, author, date, etc.
Remove dead or commented pragmas and directives.
Trim trailing whitespaces.
The assignment was superfluous in general case and incorrect in specific
case when the algorithm was given a lambda expression.
The copy assignment operator is defined as deleted for lambda
expressions.
Add minimal test for for_each_pixel algorithm to verify it compiles with
lambda expression.
The previous name is too generic and prone to variable shadowing,
causing compilation warnings (eg. vector named buffer in JPEG-s
reader::read_rows method).
* Applies patch from John Femiani submitted via Trac
https://svn.boost.org/trac10/ticket/2222 description:
It would be convenient if GIL views modeled ReversibleCollection concept.
In fact they almost do already. Without modeling this concept, it is
hard to use an image view with boost::range algorithms.
* Add related image_view concepts for Collection, ForwardCollection,
ReversibleCollection.
* Add tests for the new concepts.
* Add run-time tests for the new image_view methods.
