Updated the Boost Build generator_selection.py test to not use the default CPP --> OBJ generator and use a custom 'simple copy file generator' to avoid problems with some test runners using compilers/toolsets refusing to compile sources with unknown extensions. This should fix the test failing on IBM's AIX test runner.

Corrected a badly formed end-user error message in Boost Build's utility.jam module.

End-user error message in Boost Jam based Boost Build utility.ungrist() rule did not correspond to the actual rule's implementation. It implied that the value '<>' should be acceptable while it was not. Python based Boost Build implementation on the other hand accepted such values. Updated the original rule to accept this value as well.

Added a few new internal unit tests for Boost Build's utility.unquote() rule.

Extracted static/shared library testing out of the generators_test.py Boost Build test and into a separate new static_and_shared_library.py test. Updated the test a bit in the process to make it test some additional use cases.

Made the generators_test.py Boost Build test more detailed.

Reorganized the Boost Build generators-test.py test completely. Now no longer used regular OBJ, LIB & EXE target generators to avoid having to deal with specific compiler/linker features, e.g. some compilers causing test failures by returning an error code on a warning about an unexpected source file .target_cpp extension being used. Removed lots of duplication, made the test code much more readable, reviewed and cleaned up all the comments.

Updated the rest of the Boost Build generator_selection.py test to not use the default CPP --> OBJ generator and use a custom 'simple copy file generator' instead to avoid problems with misconfigured test runners. Also made the test a bit stricter. This should fix the test failing on Sandia-darwin-intel test runners.

Corrected a bug in the Boost Build testing framework causing it to read file content with an additional newline character at the end when it already had one there instead of when it was missing.

git-svn-id: http://svn.boost.org/svn/boost/trunk@78968 b8fc166d-592f-0410-95f2-cb63ce0dd405
Made the Boost Build example_make.py test explicitly use its own Python interpreter instead of relying on the 'python' executable being available on the system path.

Updated the generators_test.py Boost Build test to explicitly check some conditions that were before only listed in test code comments but never explicitly tested.

Added a missing source file for the generators_test.py Boost Build test that got missed in a previous commit (revision [78964]).
