bb6f420228 Add __getcwd() syscall, and have getcwd() take a shot at it. 
If your kernel doesn't support __getcwd() or if __getcwd() cannot
deliver because of cache expiry, it does the canonical thing.

ef7710b201 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.

39f822f3ed 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).

02b5c984e2 Merge in the safe chdir changes from Todd Miller's mods to the OpenBSD 
tree.  Also merge in fix to NetBSD PR #1495.  These represent 1.3-1.9 in
the OpenBSD tree.  Make minor KNF changes to new code (which is in the
OpenBSD as 1.10).  This avoids the symlink race problems.

These patches should go into 2.2.5 before the ship if they don't
break anything in -current.

1bb1b82690 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.
