Remove trailing whitespace from most CMake and C/C++ code

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/ \+$//'

 # If the dependencies of Five are emitted, and then we attempt to emit the
 # dependencies of Seven, then we find that they have already been done. So:
 #  Original line:      Eight Five
-#  Add deps of Five:   Eight Five Two ... NoDepA 
+#  Add deps of Five:   Eight Five Two ... NoDepA
 # Now, we must make sure that Seven gets inserted between Five and Two, and
 # not at the end. Unfortunately, if we get it wrong, the test will only
 # fail on a platform where the link order makes a difference.
