They only make sense in the context of directory ACLs, and attempting
to set them on regular files results in errors, causing a recursive
setfacl invocation to abort.
This is derived from patches by Shawn Webb <shawn.webb@hardenedbsd.org>
and Mitchell Horne <mhorne063@gmail.com>.

Add a -R option to setfacl to operate recursively on directories, along
with the accompanying flags -H, -L, and -P (whose behaviour mimics
chmod).
A patch was submitted with PR 155163, but this is a new implementation
based on comments raised in the Phabricator review for that patch
(review D9096).

This self-written compiler warning, which is hopefully going to be
committed into LLVM sources soon, warns about potentially missing
`static' keywords, similar to -Wmissing-prototypes.
- bin/pax: Move external declaration of chdname and s_mask into extern.h.
- bin/setfacl: Move setfacl.c-specific stuff out of setfacl.h.
- sbin/mount_fusefs: Remove char *progname; use getprogname().
- others: add `static' where possible.
Initially, 'acl' (an 'acl_t *') is allocated, and its ACCESS_ACL and
DEFAULT_ACL fields are passed to the 'libc' ACL routines for subsequent
allocation. If the '-m' option (merge existing ACL with a new one) is
specified, then 'set_acl_mask()' will be called and passed one of the
two ACLs. This function, in turn, replaces this given ACL structure by
another, freshly allocated. However, the pointer in the 'acl' variable
in the caller is not updated. The caller then proceeds to free the ACL,
incurring in a double free condition.

Before this fix the -h flag was ignored (i.e. setfacl
always set the ACL on the file pointed to by the symbolic
link even when the -h flag requested that the ACL be set
on the symbolic link itself).
next read filename overwrite previous one, resulting in acl being
applied only to the last name in the list.

similar to "-h" on chown, chmod, etc, causing the operation to occur
on a final symlink in the provided path, rather than its target.

required by POSIX.1e. This maintains the current 'struct acl'
in the kernel while providing the generic external acl_t
interface required to complete the ACL editing library.
o Add the acl_get_entry() function.
o Convert the existing ACL utilities, getfacl and setfacl, to
fully make use of the ACL editing library.
