* ctypesgencore/libraryloader.py
  (LibraryLoader, LinuxLibraryLoader, DarwinLibraryLoader): Update to search
  LD_LIBRARY_PATH before the install dir, so that folks can test libraries in
  the build dir before installing.
  (PosixLibraryLoader): Renamed from LinuxLibraryLoader. Update to (hopefully)
  work on all Posix platforms besides Mac OS X and cygwin.
