Simplify CMake per-source license notices Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

Convert CMake non-find modules to BSD License This adds copyright/license notification blocks CMake's non-find modules. Most of the modules had no notices at all. Some had notices referring to the BSD license already. This commit normalizes existing notices and adds missing notices.

Convert CMake-language commands to lower case Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case. Run the following shell code: cmake --help-command-list | grep -v "cmake version" | while read c; do echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | xargs -0 sed -i -f convert.sed && rm convert.sed

OS X: Enable command-line build without tools in PATH Teach modules CMakeDetermineCompiler and CMakeUnixFindMake to ask Xcode where to find the compiler or make tools, using 'xcrun --find', if none is found in the PATH. Teach module Platform/Darwin to add the path to the SDK to CMAKE_SYSTEM_PREFIX_PATH so that find_* command look there. Also add the SDK /usr/include directory to the implicit include list in CMAKE_${lang}_IMPLICIT_INCLUDE_DIRECTORIES to suppress explicit -I options for it.
