 binary_find -> binary_search.
include_directory: Add missing include.

The cmGeneratorExpression is used here, but the header for it is not
in the include heirarchy.  This would be a compile error if the file
were compiled as a standalone translation unit, but it is instead
used in a mini-unity-build by inclusion in cmCommands.cxx. The header
for cmGeneratorExpression happens to be included first, so the
compilation works fine.

IDEs do not know this however, and flag the use as an error.
cmGlobalGenerator: Remove unused variable.
Makefile: Fix comment indentation.
Tests: Remove some trailing black lines.
Help: Document the package registry in cmake-packages.7

Help: Format find_package() command documentation

Add inline markup and explicit markup block syntax as needed.
Add cross-references to other documentation as appropriate.
FindBoost: Add suport for custom namespaces

When building boost with an alternate namespace the libraries generated
will have a different naming convention.  This is often done to ensure
no symbol conflicts with external libraries built against a different
version of boost.  If the namespace used is "myprivateboost::" instead
of "boost::" then the libraries built will be named myprivateboost_foo
instead of boost_foo.  Add an option to specify a custom namespace used
to alter the library names that get searched for.

Help: Document the purpose of usage requirements clearly.

People will be tempted to put things there for convenience, thereby
causing conflicts similar to

 http://thread.gmane.org/gmane.comp.compilers.clang.devel/35162/focus=35169

where it is conceivable that the LLVM developers could put a flag on
a target for convenience, which would cause conflicts for some downstreams.
FindOpenSSL: Prefer OPENSSL_ROOT_DIR first (#14764)

Use hints computed from this explicit variable before those
computed by PkgConfig.  They are more specific.
