On the "unreadable directories can be globbed (users/24619, users/24626)"
test, resolve conflicts by removing the Cygwin-only skip that has been added
in master, since the test is passing on this branch. This effectively reverts
workers/45492. See discussion starting in workers/45504.

ChangeLog
Test/D02glob.ztst
Test/V01zmodload.ztst
If we use kill to test for continued existence of a process group,
we should check on failure that the error is ESRCH, as EPERM
indicates the group still has memebers but running privileged
so should be left alone.
The following case was encountered in the wild:
% zsh; echo "$?"
% trap 'exit 5' TERM
% kill ''
5
This behaviour seems more likely to be the result of bugs in programs
(e.g. `kill -9 "$unsetvar") rather than being desirable
behaviour to me. It also seems unintentional judging by the code and
documentation, since it comes about as a result of the fact that:
- `isanum` returns true for empty strings (since an empty string
technically only consists of digits and minuses...);
- `atoi`, when passed a pointer to an invalid number, returns 0;
- `kill(0, signal)` sends the signal in question to all processes in the
current process group.
There are (at least) two ways to solve this issue:
1. Add special handling to `kill` to avoid this case. See this patch[0]
for a version that does that.
2. Change how isanum behaves. Since the only two call sites that use it
both seem like they should handle the case where the input char array
is empty, that seems like a reasonable overall change to me.[1]
After this patch:
% trap 'exit 5' TERM
% kill ''
kill: illegal pid:
The regression test for `kill` without a sigspec is also included in
this commit, as previously it's not possible to test it trivially as it
would still kill the test runner in expected-to-fail mode; see
discussion in workers/45449.
0: workers/45426: https://www.zsh.org/mla/workers/2020/msg00251.html
1: The other call site using isanum() is the fg builtin, but in that
case we just fail later since we can't find any job named '', so no
big deal either way. It's the kill case which is more concerning.
- Fix retval handling in bin_setopt()
- Don't skip_setuid / skip_setgid. It's not our place to optimize away noops
(that might not even _be_ noops; they might change the saved uid…).
- Remove HAVE_* guard checks around functions that are used unguarded elsewhere.
- Use bsd-setres_id.c from OpenSSH to provide setresuid() / setresgid()
everywhere, and thus simplify the ifdef soup. Fix some preëxisting
bugs in the macro definitions of setuid() (do we still need that one?).
- Fix zwarning() format codes for variadic arguments type safety
- Restored a comment from HEAD
- Fix failure modes around initgroups()
- Compared privilege restoration code with OpenSSH's permanently_drop_uid() and
updated as needed
- Add E01 PRIVILEGED sanity checks
