Introduction of CPACK_VERBATIM_VARIABLES variable

If variable is set to TRUE, values of all variables prefixed with CPACK_
will be escaped so special characters such as dolar sign, quotes or
foreward slash will not be lost. By default variable is treated as set
to FALSE for back compatibility.

The cpack_encode_variables macro is changed into a function to remove
scope pollution. There should be no other effects.

* The :module:`CPack` module no longer mangles settings with CMake-special
characters when they're used as defaults for other settings. The macro
``cpack_set_if_not_set``, which was responsible for this, is now deprecated.
* The :module:`CPack` module gained a new setting, ``CPACK_VERBATIM_VARIABLES``,
which can be used to ensure the cpack program receives the settings' values
exactly as they were set, even if they contain CMake-special characters.
For compatibility, it's off by default.
