GNU-CXX already has complex logic and sets the _result to 0 before
tests which may set it to something else.
Change the other modules to be consistent with that.
Update json/json.h to account for our lack of autolink.h. Update
json/config.h to include KWSys Large File Support configuration so that
consistent stream libraries are used (on AIX with XL).
Add a cm_jsoncpp_reader.h header to include the CMake-provided copy of
the json/reader.h header from CMake sources.
Add support for a special URL template to map the fetch operation
to a project-specified .cmake script insead of using file(DOWNLOAD).
Extend the Module.ExternalData test to cover the behavior.
Extend the RunCMake.ExternalData test to cover error cases.
Move the basic DATA{} description to a section just before the
file series description. Move all sections on referencing files
into subsections of a common "Referencing Files" section.
Subsume example usage into the introduction since it gives a
high-level starting point to understand the rest of the docs.

The sweeping pattern change in commit 238dd2fb (Use insert instead of a
loop in some cases, 2014-11-22) accidentally changed the iterator range
used on the queue in cmCTestBuildHandler::ProcessBuffer. Instead of
ending at the iterator positioned at the next newline to populate
CurrentProcessingLine, it was changed to go to the end of the queue.
This causes the line to contain newlines and possibly be cut off in the
middle of a line. Fix this regression by restoring use of the proper
end-of-line position.
The compiler in the PATH on mac is a stub for a different delegate
depending on the environment. Rather than requiring xcode-select to
change the used Xcode globally, users should be able to choose the
compiler per-session. That is possible with the DEVELOPER_DIR
environment variable.
However, the environment can change between running CMake and invoking
the build. In such cases, CMake prefers to record the relevant paths
from the environment and use them when invoking the build. That is not
currently done for the compilers on APPLE, so the compiler used is not
the one reported when running cmake:
$ DEVELOPER_DIR=/Applications/Xcode2.app/Contents/Developer/ cc --version
Apple LLVM version 6.0 (clang-600.0.51) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix
$ DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer/ cc --version
Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix
Update that now by querying Xcode for the correct compiler path if
the compiler located by ordinary means is located in /usr/bin.
The second hunk of commit 07d1f6fc (Features: Properly evaluate if the
compiler supports cxx_final, 2014-12-31) was a workaround for a bug in
the COMPILE_FEATURES generator expression that caused it never to return
0. Revert the workaround so we can fix the bug instead.
