c86afb6bc0 signal() returns SIG_ERR, not just -1. The sys/signal.h header file
provides the cast from -1 to the signal() return type, so no further
casting by programmers should be required.

Pointed out by: bde (of course).

12228287c1 Fix _listmatch() again so that it works with group lists containing only
one group. Thanks to Dirk Froemberg for supplying a patch for this. I will
be closing out the PR and moving this to the 2.2.5 branch later: my login
sessions to freefall from Columbia are ridiculously spotty today.

645c4be38a Move the trampolines for dlopen and related functions from crt0.o
into libc.  This reduces the size of every dynamically linked
executable by 248 bytes, and it reduces the size of static executables
by a lesser amount.  It also eliminates some global namespace
pollution.

With this change in place, the source for dlfcn.h should probably
be moved to "/usr/src/include".  I'll save that for another day.

Compatibility note:  Programs which use dlopen, if compiled on
systems with this change, will not run on systems with a libc from
prior to this change.  Very few programs use dlopen, so I think
that is OK.

1e69872de7 Started getting rid of the compatibility cruft for the Lite1 mount()
and the pre-Lite2 vfsconf interfaces.

For getvfsent.c, just define _OLD_VFSCONF.  This will give the
current default macro hacks in <sys/mount.h> when the default is
reversed.  This is an intermediate step.

f1d896d117 Make a couple of the stat flags dependent on the sys/stat.h header file
that this source is compiled against. This source is referenced by
install which is needed as a build tool and must be able to compile
against NetBSD headers and libraries if we have a hope of supporting
another architecture.

With this change, that's two working programs down and 3945 (?) to go.
The other one was make, but that didn't need any changes to work under

6173688707 Remove old SIGALRM absorbing back-compat code. It wasn't working at all
for the entire time that it was there, so obviously nothing needs it
anymore.

Note, unix98/single-unix spec v2 says that usleep() returns an int rather
than a void, to indicate whether the entire time period elapsed (0) or an
error (eg: signal handler) interrupted it (returns -1, errno = EINTR)
It is probably useful to make this change but I'll test it locally first
to see if this will break userland programs [much]...

9f375c3252 Give up on the "try and compensate for broken programs" cruft and revert
back to the original single nanosleep() implementation.  This is POSIX and
Unix98 (aka single-unix spec v2) compliant behavior.  If a program sets
alarm(2) or an interval timer (setitimer(2)) without a SIGALRM handler
being active, sleep(3) will no longer absorb it, and the program will get
what it asked for..... :-]

The original reason for this in the first place (apache) doesn't seem to
need it anymore, according to Andrey.

1df595f25d Fixed searching of $PATH in execvp(). Do what sh(1) should do according
to POSIX.2.  In particular:

- don't retry for ETXTBSY.  This matches what sh(1) does.  The retry code
  was broken anyway.  It only slept for several seconds for the first few
  retries.  Then it retried without sleeping.
- don't abort the search for errors related to the path prefix, in
  particular for ENAMETOOLONG, ENOTDIR, ELOOP.  This fixes PR1487.  sh(1)
  gets this wrong in the opposite direction by never aborting the search.
- don't confuse EACCES for errors related to the path prefix with EACCES
  for errors related to the file.  sh(1) gets this wrong.
- don't return a stale errno when the search terminates normally without
  finding anything.  The errno for the last unsuccessful execve() was
  usually returned.  This gave too much precedence to pathologies in the
  last component of $PATH.  This bug is irrelevant for sh(1).

The implementation still uses the optimization/race-inhibitor of trying
to execve() things first.  POSIX.2 seems to require looking at file
permissions using stat().  We now use stat() after execve() if execve()
fails with an ambiguous error.  Trying execve() first may actually be a
pessimization, since failing execve()s are fundamentally a little slower
than stat(), and are significantly slower when a file is found but has
unsuitable permissions or points to an unsuitable interpreter.

e882d43eca Improve the innetgr() NIS+ compat kludge. We should only fail over to the
'slow' lookup if we get a YPERR_MAP (no such map in server's domain) error
instead of failing over on any error. In the latter case, if the 'fast'
search fails legitimately (i.e. the user or host really isn't a member
of the specified netgroup) then we end up doing the 'slow' search and
failing all over again. The result is still correct, but cycles are
consumed for no good reason.

Also removed the #ifdef CHARITABLE since the compat kludge is no longer
optional.

c17942ca57 NIS+ compatibility kludge. A long time ago, I set up innetgr() so
that if searching through the special netgroup.byhost or netgroup.byuser
maps didn't work, we would roll over to the 'slow' method of grovelling
though the netgroup map and working out the dependencies on the fly.
But I left this option hidden inside an #ifdef CHARITABLE since I
didn't think I'd ever need it.

Well, the Sun rpc.nisd NIS+ server in YP compat mode doesn't support
the .byhost and .byuser reverse maps, so the  failover is necessary
in order to be compatible. *sigh*

This closes PR #3891, and should be merged into RELENG_2_2.
