file-has-acl: new module, split from acl

And add a new module file-has-acl-tests to match.
I ran into a problem with the recent changes to the acl module,
as they introduced a typo 'test use_xattrs = 0' into 'configure'.
When using the fixed version with Emacs, I discovered that
file-has-acl wasn't separated out well enough for Emacs (e.g., it
had multiple libraries, but needed only one), so I fixed that too.
* NEWS: Document this incompatible change.
* modules/file-has-acl, modules/file-has-acl-tests: New files.
* m4/acl.m4 (gl_FUNC_ACL_ARG): New macro, split from gl_FUNC_ACL.
Initialize gl_need_lib_has_acl.
(gl_FUNC_ACL): Require it.
Simplify use of 'test'.  Set LIB_HAS_ACL if gl_need_lib_has_acl.
Move the file-has-acl.c-relevant stuff to ...
(gl_FILE_HAS_ACL): ... this new macro.  Rewrite to fix 'test
use_xattrs = 0' typo, and omit some needless work.  Set
gl_need_lib_has_acl=1 if we'll need LIB_HAS_ACL to be set
when gl_FUNC_ACL is called.
* modules/acl (Files, lib_SOURCES): Remove lib/file-has-acl.c.
(Link): Remove $(LIB_HAS_ACL).
* modules/acl-tests (Files, Depends-on, configure.ac, TESTS)
(check_PROGRAMS): Move stuff relevant to file-has-acl to
modules/file-has-acl-tests.
(test_file_has_acl_LDADD): Move to modules/file-has-acl-tests.
