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.

9e06e6da51 Some adjustments for the resolver use of poll(). For some reason I thought
an unimplemented syscall returned ENOSYS, rather than EINVAL.  I have run
statically linked code with this wrapper and it does appear to work fine
on 2.2-stable which doesn't have poll().  ktrace shows the poll syscall fail
once and the fallback to select() working.

535db1806c Call poll(2) from within the resolver but adapt to older kernels without it
if necessary.  This removes the need to malloc large fd_set's for selecting
on high fd's (larger than FD_SETSIZE at libc compile time).

The syscall adaptive stuff only happens on the very first call.  SIGSYS
is masked, and if the call to poll fails with ENOSYS, then we use select
for the life of the program.  If poll does not fail with ENOSYS, then we
always use poll and skip the once-off signal masking gunk.

This may be overkill, but it saved my neck a few times while working on
multiple different sets of kernel sources, some with poll, some without.

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

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).

9295bb8d0d Add a stub version of getpublickey(), in order to eliminate an
undefined symbol referenced from libc.  Without the stub, it is
impossible to execute any program using the shared library if
LD_BIND_NOW=1 is in the environment.  The stub always returns
failure, but it can be overridden outside the library when necessary.

I don't know whether this is the "correct" fix, but it is intolerable
to have any undefined symbols referenced from libc.
