A few more symlink-related fixes. Fix a bug triggered by cp
--parents and symlinks. Close some race conditions possible when
the destination replaces a newly-created file with a symlink.
* NEWS: Document that 'cp --parents' no longer mishandles
symlinks in file name components of source.
* src/copy.c (HAVE_LCHOWN): Default to false.
(lchown) [!defined HAVE_LCHOWN]: Define to chown, for convenience.
* src/cp.c (lchown) [!HAVE_LCHOWN]: Likewise.
* src/install.c (lchown [!HAVE_LCHOWN]: Likewise.
* src/copy.c (set_owner): Use lchown instead of chown, for safety
in case the file got replaced by a symlink in the meantime.
* src/cp.c (re_protect): Likewise.
* src/install.c (change_attributes): Likewise.
* src/copy.c (copy_internal): Use ordinary C rather than an #if.
* src/cp.c (lchown) [!HAVE_LCHOWN]: Define to chown, for convenience.
(struct dir_attr): Cache the entire struct stat of the directory,
rather than just its mode, so that we needn't stat the directory
twice (which can lead to races).
(re_protect): Don't use XSTAT as that's not appropriate in
this context (symlinks should be followed here). Instead, use
the cached stat value.
(make_dir_parents_private): Save dir's entire struct stat, not
just its mode.
* tests/cp/cp-parents: Add test to check against bug with
cp --parents and symlinks.
