Emacs 24 and above support a generic "prog-mode" to simplify definition
of programming modes. Derive "cmake-mode" from it since we are a
programming mode.
Control flow keywords will now be highlighted as such. Variable names
will be also be recognized. Adjust function name highlighting to work
in places other than the start of a line.

The --trace option is helpful, but sometimes, what you're looking for is
deep under many layers of function calls and figuring out what instance
of the function call you're looking at is tedious to determine (usually
involving patching and message()). Instead, add a --trace-expand option
to trace while expanding commands into what CMake actually sees.
Instead put a sentinal empty entry in the container when a property
is overwritten. Use this sentinal when reading from the containers.
Use iterator::operator+(size_type) directly instead of std::advance,
because this only really makes sense if using RandomAccessIterators.
The actual file timestamp dependency is known to not work on
Visual Studio or Xcode generators. Tolerate such failure for
these generators (Tests/CustomCommand already covers using
OBJECT_DEPENDS to pull a custom command into a target, and
that still works with these generators).
