(dest_info_init): Make the hash table code use it.
(record_dest): Store each DEST in malloc'd memory. Hence the above.
Use dest_info_free to free the `ent' we couldn't insert.
no longer equivalent to `cp -d'.
`cp -d' is equivalent to `--no-dereference --preserve=links'.
cp's -P option means --no-dereference, not --parents.
Describe new optional argument to --preserve.
Describe new option: --no-preserve=ATTRIBUTE_LIST.
Use --parents to get the old meaning.
(enum) [NO_DEREFERENCE_OPTION]: Remove member.
(long_opts): Associate --no-dereference with `-P'.
(usage): Update description of -P.
(main): Remove local, used_P_option, and code to warn
that the meaning of -P would be changing.
describing the test for when to record (via remember_copied)
a <dst_path, source_dev, source_ino> triple.
Relax the test that guards the hard-linked-dir check and
the hard-link-preserving code.
(enum) [NO_PRESERVE_ATTRIBUTES_OPTION]: New member.
(enum) [PRESERVE_ATTRIBUTES_OPTION]: New member.
(long_opts): Separate -d and --no-dereference options.
Add `no-preserve'.
Separate -p and --preserve options.
The long-named --preserve now accepts optional arguments; -p doesn't.
(usage): Describe additions and changes.
(cp_option_init): Initialize new member, preserve_links, to 0.
(decode_preserve_arg): New function.
(main) [case 'a']: Set preserve_links to 1.
[case 'd']: Set preserve_links to 1.
Add `case' for long-named --no-dereference.
Handle long-named --no-preserve and --preserve.
slightly-modified copies of those that used to be in cp-hash.c.
(struct entry) [coll_link]: Remove member.
(struct htab): Remove.
(hash_reset, hash_init, hash_insert2, hash_insert): Remove functions.
Include hash.h and same.h.
(htab): Change type of global to `struct hash';
(entry_hash, entry_compare, hash_ins): New functions.
(count_entry): Use hash_ins instead of hash_insert.
