ls: Add support for SELinux and a slightly modified -Z option.

I started with the patches from Red Hat. The entries below tell how the code evolved. * src/ls.c (print_long_format, print_file_name_and_frills): When there is no security context (due to getfilecon/lgetfilecon failing with e.g. ENOTSUP), print it as "?", not "". * src/ls.c (print_file_name_and_frills): Make -Z work without -l. (length_of_file_name_and_frills): Likewise. * src/ls.c: Remove the --lcontext and --scontext options. Change the way -Z, --context work so that it no longer implies -l. Thus, -Z -l will work like -lcontext and -Z without -l will work like --scontext. Adjust tests to reflect new 'ls -l' syntax -- affects only systems with SELinux when operating on a file with no ACL. These tests assumed that everything before the first space on each line is the 10-byte mode string. But there may also be a "+" in the 11th column, just before the space. However, note that this is not new. The same thing would have happened even without the change below, when listing a file with an ACL. * tests/chmod/equals, tests/cp/cp-parents, tests/cp/fail-perm: * tests/cp/link-preserve, tests/install/basic-1, tests/misc/mknod: * tests/mkdir/parents, tests/mkdir/special-1, tests/mv/partition-perm: Don't make compilation depend on USE_ACL. An SELinux security context counts as an "alternate access control method", so ls must output a "+" for each file with a security context. * src/ls.c [struct fileinfo] (have_acl): Declare unconditionally. (FILE_HAS_ACL): Remove macro definition. Use f->have_acl directly. (gobble_file): Record whether a file has a security context, and update the condition used to determine whether to print the "+". (gobble_file): Call getfilecon/lgetfilecon also when format == long_format, so that we get the "+". * src/ls.c (gobble_file): Add a comment explaining why (with a security context option) ls doesn't exit nonzero due to e.g., getfilecon failing with errno == ENOTSUP. * src/ls.c (gobble_file): Ignore failure of getfilecon if it's due to ENOTSUP. * src/ls.c (gobble_file): Factor out three small blocks using getfilecon and lgetfilecon. Don't ignore return value from getfilecon and lgetfilecon. * src/ls.c (print_long_format): Don't use ?: (empty 2nd arg with C ternary operator). (print_scontext_format): Likewise. (print_scontext): Declare to be "bool", not int. Adjust uses. * src/Makefile.am (dir_LDADD, ls_LDADD, vdir_LDADD): Add $(LIB_SELINUX). * tests/misc/chcon: New file. * tests/misc/chcon-fail: New file. * tests/Makefile.am (check-root): Run new, root-only misc/chcon test. * tests/misc/Makefile.am (TESTS): Add chcon and chcon-fail. * tests/misc/Makefile.am (TESTS): Add selinux. * tests/misc/selinux: New file. * tests/help-version: Skip chcon.
