It's silly to call sysctl() to get the value of _PATH_STDPATH from
<paths.h> when we can just use it directly. This greatly simplifies
the implementation. (This is also part of my grand scheme to get
rid of sysctl's `user' category, which should never have been created.)
Use strlcpy() instead of strncpy() as it has the exact semantics we want.
__dlfunc_t to dlfunc_t to match what I have proposed to the Austin
Group. (This also makes it easier for applications to store these
values before they decide what to do with them, e.g., in a wrapper
function.)
Add new dlfunc() interface, which is a version of dlsym() with a
return type that can be cast to a function pointer without turning
your computer into a frog.

this is being done inside the new cru2x() routine which takes a

former. This also has the pleasant sideaffect of removing some

because libc/rpc/key_call.c references uname(), and ps/print.c also
defines uname(), and ps is linked statically. This leads to a symbol
clash. The userland uname(3) kinda sucked anyway as the hostname
etc was too short. And since the libc rpc interface now uses
the utsname.nodename which gets truncated, I was tempted into doing
something about it. Create a new userland uname function, called
__xuname() which takes an extra argument that allows you to change
the size of the fields. uname() becomes a static inline function
in sys/utsname.h that passes the extra argument in. struct utsname
has its field members expanded by default now in userland.
We still provide a 'uname' externally linkable function for things
that either think that they ``know'' the utsname format and assume
32 character strings and bypass the include file, or objects that
are linked against old libcs. ie: just about every plausible
case that I can think of is covered. Should we ever change the
default lengths again, a libc major bump should not be required
as the size is now passed to the function.
XXX the uname(2) in the kernel is for FreeBSD 1.1 binary compatability!

Bring in required TLI library routines to support this.
Since we don't support TLI we've essentially copied what NetBSD
has done, adding a thin layer to emulate direct the TLI calls
into BSD socket calls.
This is mostly from Sun's tirpc release that was made in 1994,
however some fixes were backported from the 1999 release (supposedly
only made available after this porting effort was underway).
The submitter has agreed to continue on and bring us up to the
1999 release.
Several key features are introduced with this update:
Client calls are thread safe. (1999 code has server side thread
safe)
Updated, a more modern interface.
Many userland updates were done to bring the code up to par with
the recent RPC API.
There is an update to the pthreads library, a function
pthread_main_np() was added to emulate a function of Sun's threads
library.
While we're at it, bring in NetBSD's lockd, it's been far too
long of a wait.
New rpcbind(8) replaces portmap(8) (supporting communication over
an authenticated Unix-domain socket, and by default only allowing
set and unset requests over that channel). It's much more secure
than the old portmapper.
Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
to support TI-RPC and to support IPV6.
Umount(8) is also fixed to unmount pathnames longer than 80 chars,
which are currently truncated by the Kernel statfs structure.
