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names and years are hard to maintain and often out-of-date or plain wrong.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.

It is now at open.cdash.org and does not start in "/CDash".

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

Our Git commit hooks disallow modification or addition of lines with
trailing whitespace.  Wipe out all remnants of trailing whitespace
everywhere except third-party code.

Run the following shell code:

git ls-files -z -- \
 bootstrap doxygen.config '*.readme' \
 '*.c' '*.cmake' '*.cpp' '*.cxx' \
 '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \
 '*.mm' '*.pike' '*.py' '*.txt' '*.vim' |
egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' |
egrep -z -v '^(Modules/CPack\..*\.in)' |
xargs -0 sed -i 's/ \+$//'

Extract upstream libarchive using the following shell code.

url=https://libarchive.googlecode.com/svn/trunk
v=3.0.1
r=3950
paths="
  CMakeLists.txt
  COPYING
  CTestConfig.cmake
  build/cmake
  build/pkgconfig
  build/utils
  build/version
  libarchive/*.*
"
date=$(svn log -q -c$r $url |
       sed -n "/^r/ {s/[^|]*|[^|]*|//;p;}")
svn export -r$r $url libarchive-$v-r$r &&
mkdir libarchive-$v-r$r-reduced &&
(cd libarchive-$v-r$r && tar c $paths) |
(cd libarchive-$v-r$r-reduced && tar x)
echo "r$r date: $date"

Moved call to cache CDash version information to cmCTest::initialize.  Also added a 3 second timeout when requesting the version from the server.  Added an option to the CTestConfiguration that will be used to determine whether to query the version information at all.  (Behavior for this setting is not yet defined.)  Updated CMake's local CDash version setting to 1.6.

Added support for CTest awareness of the CDash version.  This will help forward compatibility for both tools.  Note that this changeset effectively makes the default to disable output compression.  Now, to enable output compression, the CDASH_CTEST_VERSION must be explicity set to >= 1.6.  Automated detection of the CDash version is the next step.

This converts the CMake license to a pure 3-clause OSI-approved BSD
License.  We drop the previous license clause requiring modified
versions to be plainly marked.  We also update the CMake copyright to
cover the full development time range.
