r292530:

- Use 1 for an exit code instead of -1 with err, errx, and exit
- Add unistd.h for getuid(3)
- Sort #includes

r292546:

- Convert testcase to TAP format
- Use nitems(x) instead of handrolled sizeof(x) / sizeof(*x) macro
- Do not mark count != 0 case with bsde_get_rule_count as a failure; this
  generates false positives on systems with ugidfw rules set on it

r292650:

Move mac_bsdextended check up before running the test_libugidfw_strings testcases

I realize that these tests could be run before mac_bsdextended is loaded, but
it would overcomplicate things to special case handle the testcases before doing
the mac_bsdextended(4) feature check

The testcases will be split up so they can be run separately in the near future

r292651:

Delete the comment about running `test_libugidfw_strings` before testing
`mac_is_present` so it doesn't accidentally confuse people
