Changes to support building with _POSIX_SOURCE set to 199309L:

1. Add sys/_posix.h to handle those preprocessor defs that POSIX
says have effects when defined before including any header files;

2. Change POSIX4_VISIBLE back to _POSIX4_VISIBLE

3. Add _POSIX4_VISIBLE_HISTORICALLY for pre-existing BSD features now
defined in POSIX.  These show up when:

_POSIX_SOURCE and _POSIX_C_SOURCE are not set or
_POSIX_C_SOURCE is set >= 199309L

and vanish when:

_POSIX_SOURCE is set or _POSIX_C_SOURCE is < 199309L.

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.

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

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

9f375c3252 Give up on the "try and compensate for broken programs" cruft and revert

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..... :-]

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.

d030d2d2ae Many places in the code NULL is used in integer context, where
plain 0 should be used.  This happens to work because we #define
NULL to 0, but is stylistically wrong and can cause problems
for people trying to port bits of code to other environments.

77909f5978 Initial elf nlist support, mostly stolen from OpenBSD (they use standard
#defines that are compatable with ours).  I made some some minor tweaks

Again, this is off by default for the moment.  This probably should be
split into seperate files (like some of our other libc files that could
do with some splitting).

be159dcaf7 Re-activate the nanosleep style using code, but with the signal handling
semantics of the old sleep for compatability with a few decades of expected
side effects.  Apache breaks if we just use nanosleep() for some reason,
here we use a new signanosleep() syscall which is kinda like a hybrid of
sigsuspend and nanosleep..

These changes add the ability to specify that a UFS file/directory
cannot be unlinked. This is basically a scaled back version
of the IMMUTABLE flag. The reason is to allow an administrator
to create a directory hierarchy that a group of users
can arbitrarily add/delete files from, but that the hierarchy
itself is safe from removal by them.
If the NOUNLINK definition is set to 0
then this results in no change to what happens normally.
(and results in identical binary (in the kernel)).
It can be proven that if this bit is never set by the admin,
no new behaviour is introduced..
Several "good idea" comments from reviewers plus one grumble
about creeping featurism.

0913e7ce8b Update the sleep(3)/usleep(3) code to use signanosleep(2) if compiled with

the simpler threaded nanosleep() call in libc_r..  We don't go to the same
extremes for emulating traditional sleep semantics (ie: eating any SIGALRM
that might happen) which things like apache seem to depend on.

e3c1328e9f Temporarily restore old (itimer) sleep variant because new one
(nanosleep) breaks Apache httpd badly: his childs died quickly after
number of requests (SIGPIPE). To reproduce this bug start
gdb /usr/local/sbin/httpd
run -X

and make some bunch of concurent requests (load the server pages
from 3 different places f.e.)
After short time httpd dies via SIGPIPE. It never dies with old sleep.c

In real life it looks like lots of broken images on the pages or missing
pages. Lynx says about Network read error, etc.
It seems something wrong in nanosleep signal handling.
