ENH: avoid the use of GET_TARGET_PROPERTY by testing the CMake executable instead of the test executable

BUG: Reverting fundamental type info change until it is fixed on more platforms.  It was tested on Linux, SGI, HP, Sun, OSX, Windows with nmake and VS 6, 7, 7.1, 8, Borland Make, and cygwin by hand with spaces in the path and cmake 2.0 and 2.2 before committing but still seems to be failing on some dashboards...strange.

ENH: Converting FundamentalType try-compiles into a single try-run.  All the information about the existence, size, and signedness of types can be determined in one program thanks to limits.h.

ENH: Modify API a little bit to allow arbitrary length values. Encode certain characters. Rename UNIX registry to FILE registry. More testing

ENH: Added cygcheck knowledge for --ldd option on Cygwin.  Added error message for --ldd option when no tool is available but the option was still requested.

BUG: Fixed dirname in a few cases on windows.  Now using KWSYS_SHARED_FORWARD_CONFIG_NAME setting instead of CMAKE_INTDIR directly to give choice to user code.  Updated documentation to include @KWSYS_NAMESPACE@_SHARED_FORWARD_CONFIG_NAME, @KWSYS_NAMESPACE@_SHARED_FORWARD_OPTION_PRINT, and @KWSYS_NAMESPACE@_SHARED_FORWARD_OPTION_LDD settings.

BUG: Automatic pwd/cwd path translation must check that the generated logical-to-physical mapping is correct by using realpath.

ENH: If VTK_LIBRARY_PROPERTIES is set then the properties it lists will be added to VTK library targets with SET_TARGET_PROPERTIES.  This will be useful to enable shared library versioning.

ENH: Added FundamentalType header defining platform-independent fixed size/signedness integer types.

ENH: Added TEST_KWSYS_CXX_SAME_LONG_AND___INT64, TEST_KWSYS_CXX_SAME_LONG_LONG_AND___INT64, TEST_KWSYS_CAN_CONVERT_UI64_TO_DOUBLE, and TEST_KWSYS_CHAR_IS_SIGNED.

ENH: Moved kwsys_ns and kwsysEXPORT macros to Configure.h in the case of building a kwsys source file.  This allows more than one header to be included in a kwsys source file without redefining the macros.

BUG: Revert the change to FileIsDirectory. Add FileIsSymlink and treat symlinks as files when removing directory

BUG: When removing directory, use lstat instead of stat to make sure that symlinks are treated as files and not as directories
