(delta_dirs): Changed to, instead of using the de-commissioned replace_with_nearest, replace unrelated entries with a deleta/add combo (with cheese, no pickles, onion rings, and Biggie-size that, please).
New files for the svn_fs_dir_delta test case in fs-test.c, these contain the implementation of an editor driven by svn_fs_dir_delta to in turn use filesystem calls to modify the state of a transaction tree.
(dir-delta-editor.c) New file to build.
#include dir-delta-editor.h and svn_delta.h now. Also, fixed some comments in places where tree_test_entry_t's were used.
(tree_test_t): New structure for wrapping tree_test_entry_t items.
(txn_script_command_t): New structure for making quick-n-dirty edits to a filesystem transaction.
(txn_script_exec): Function for executing the quick-n-dirty edits as defined by the array of txn_script_command_t's.
(dir_deltas): New test case for svn_fs_dir_delta().
(test_funcs): Added reference to new test dir_deltas.
