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

ENH: Extended test 0 to run the executable twice using the same process object.  This tests the reusability of the objects.

BUG: Do not increment optr by 2 after storing only one character.  Also fixed possibility of storing uninitialized characters from the last triplet.
