integration with the LTP test framework and more precise
control over test execution.

https://github.com/linux-test-project/ltp/issues/1265

The conversion splits functionality into seven focused test files.
Patch 1/8 adds acl_user_obj01.c
Patch 2/8 adds acl_mask01.c
Patch 3/8 adds acl_other01.c
Patch 4/8 adds acl_inherit01.c
Patch 5/8 adds acl_file_ops01.c
Patch 6/8 adds acl_link01.c
Patch 7/8 adds xattr_test01.c

The code has been successfully tested on SLES (kernel 6.12)
and fedora (kernel 7.0) releases on ppc64le arch.

Test build is clean in various distros. CI build report at
https://github.com/sacsant/ltp/actions/runs/26887166705
opensuse job failed due to package dependency issues.

Running the test in a distro missing acl development package
or acl library comes out clean with TCONF
