ENH: Since list file cache does not make much sense any more (because of proper list file parsing), and it actually adds unnecessary complications and make ctest scripting not work, take it out

BUG: Fix mem leaks related to th_get_pathname. Change this implementation of th_get_pathname so that it *always* returns a strdup'ed value. Callers must now free non-NULL returns from th_get_pathname. Change all callers to call free appropriately.

BUG: Fixed cmTarget::GetFullPath to not append the configuration name when only one configuration is built.  It now asks the generator what subdirectory if any to use for a given configuration name.

COMP: Fixed build on VC++ Express 2005.  Explicitly testing for MFC to determine whether to build the MFCDialog.

BUG: Removed odbc32.lib and odbccp32.lib from standard libraries on VS 8 because VC++ Express 2005 does not have them.  They are SQL database access libraries and should not be needed for every application.  User code can always explicitly link the library.  Also replacing deprecated /GZ option with /RTC1 for VS 8.  This addresses bug#2795.

BUG: Fix memory leak in libtar's kwReadDir. Use a static buffer like readdir (probably) does rather than malloc-ing a block which never gets free-d.

BUG: ABSOLUTE option should evaluate relative paths with respect to CMAKE_CURRENT_SOURCE_DIR.  This addresses bug#2797.

ENH: Improved support for user-configured search paths.  Paths given in the CMAKE_LIBRARY_PATH cmake variable are searched first, then those in the CMAKE_LIBRARY_PATH environment variable, then those listed in the call to the FIND_LIBRARY command and finally those listed in the PATH environment variable.  The support is similar for finding include files with FIND_PATH, but the variable is CMAKE_INCLUDE_PATH.

ENH: Added optional component list to the REQUIRED option of the FIND_PACKAGE command.  This addresses bug#2771.
