Dircache: Change internal cache layout.
The dircache_entry structs are now allocated subsequently from the front, allowing to treat them as an array. The d_names are allocated from the back (in reverse order, growing downwards).
This allows the cache to be moved around (needed for my buflib gsoc project). It is utilized when loading the cache from disk (on the h100), now the pointer to the cache begin doesn't need to be the same across reboots anymore.
This should save a bit memory usage, since there's no need for aligning padding bytes after d_names anymore.
