This change is to get rid of __sF[] and use seperate __stdin/out/err

because it compiled the sizeof(FILE) into every stdio using program.

try a hopefully more robust stdin/stdout/stderr. This costs an indirect

is there to not pollute application name space if the application does
not use <stdio.h> and also in case something depended on the current
behavior where stdin etc was a #define.

These functions, upon reflection and discussion, are too generically
named for a library interface with such specific functionality.
Also the api that they use, whilst ok for private use, isn't good
enough for a libc function.
Additionally there were complications with the build/install-world
process. It depends heavily upon xinstall, which got broken by
the change in api, and caused bootstrap problems and general mayhem.
There is work in progress to address future problems that may be
caused by changes in install-chain tools, and better names for
{g|s}etflags can be derived when some future program requires them.
For now the code has been left in src/lib/libc/gen (it started off
in src/bin/ls).
It's important to provide library functions for manipulating file
flag strings if we ever want this interface to be adopted outside
of the source tree, but now isn't necessarily the right moment

-But let BSDs sync their API as de-facto.
And after some discussion, it is announced that
-add update to iruserok() as iruserok_sa()
-no ruserok() API change(it is only updated internaly)

-ruserok() internal update (use iruserok_sa() inside)
-removal of ruserok_af()
-change iruserok_af() as static functioin, and also prefix the name with __.
-add iruserok_sa() (Just call __iruserok_af() inside)
-adding flag AI_ALL to getipnodebyaddr() called from __icheckhost().

locking functions. If an application loads a shared object with
dlopen() and the shared object has an init function which requires
lazy binding, then _rtld_bind is called when the thread is already
inside the dynamic linker. This leads to a recursive acquisition
of the lock, which I was not expecting -- hence the assert failure.
This work-around makes the default locking functions handle recursive
locking. It is NOT the correct fix -- that should be implemented
at the generic locking level rather than in the default locking
functions. I will implement the correct fix in a future commit.

Also add a default locking method that is used up until dllockinit()
is called. The default method works by blocking SIGVTALRM, SIGPROF,
and SIGALRM in critical sections. It is based on the observation
that most user-space threads packages implement thread preemption
with one of these signals (usually SIGVTALRM).
The dynamic linker has never been reentrant, but it became less
reentrant in revision 1.34 of "src/libexec/rtld-elf/rtld.c".
Starting with that revision, multiple threads each doing lazy
binding could interfere with each other. The usual symptom was
that a symbol was falsely reported as undefined at start-up time.

Most of the userland changes are in libc. For both the alpha
and the i386 setjmp has been changed to accomodate for the
new sigset_t. Internally, libc is mostly rewritten to use the
new syscalls. The exception is in compat-43/sigcompat.c
The POSIX thread library has also been rewritten to use the
new sigset_t. Except, that it currently only handles NSIG
signals instead of the maximum _SIG_MAXSIG. This should not
be a problem because current applications don't use any
signals higher than NSIG.
There are version bumps for the following libraries:
libdialog
libreadline
libc
libc_r
libedit
libftpio
libss
These libraries either a) have one of the modified structures
visible in the interface, or b) use sigset_t internally and
may cause breakage if new binaries are used against libraries
that don't have the sigset_t change. This not an immediate
issue, but will be as soon as applications start using the
new range to its fullest.

implementation requires two things:
1.) The priority queues must be protected during insertion
and removal of threads. Since the kernel scheduler
must modify the priority queues, a spinlock for
protection cannot be used. The functions
_thread_kern_sched_defer() and _thread_kern_sched_undefer()
were added to {un}defer kernel scheduler activation.
2.) A thread (active) priority change can be performed only
when the thread is removed from the priority queue. The
implementation uses a threads active priority when
inserting it into the queue.
A by-product is that thread switches are much faster. A
separate queue is used for waiting and/or blocked threads,
and it is searched at most 2 times in the kernel scheduler
when there are active threads. It should be possible to
reduce this to once by combining polling of threads waiting
on I/O with the loop that looks for timed out threads and
the minimum timeout value.
o Functions to defer kernel scheduler activation were added. These
are _thread_kern_sched_defer() and _thread_kern_sched_undefer()
and may be called recursively. These routines do not block the
scheduling signal, but latch its occurrence. The signal handler
will not call the kernel scheduler when the running thread has
deferred scheduling, but it will be called when running thread
undefers scheduling.
o Added support for _POSIX_THREAD_PRIORITY_SCHEDULING. All the
POSIX routines required by this should now be implemented.
One note, SCHED_OTHER, SCHED_FIFO, and SCHED_RR are required
to be defined by including pthread.h. These defines are currently
in sched.h. I modified pthread.h to include sched.h but don't
know if this is the proper thing to do.
o Added support for priority protection and inheritence mutexes.
This allows definition of _POSIX_THREAD_PRIO_PROTECT and
_POSIX_THREAD_PRIO_INHERIT.
o Added additional error checks required by POSIX for mutexes and
condition variables.
o Provided a wrapper for sigpending which is marked as a hidden
syscall.
o Added a non-portable function as a debugging aid to allow an
application to monitor thread context switches. An application
can install a routine that gets called everytime a thread
(explicitly created by the application) gets context switched.
The routine gets passed the pthread IDs of the threads that are
being switched in and out. I found this useful, but we can
get rid of it if you want.

HARP | Host ATM Research Platform
===================================
HARP 3
What is this stuff?
-------------------
The Advanced Networking Group (ANG) at the Minnesota Supercomputer Center,
Inc. (MSCI), as part of its work on the MAGIC Gigabit Testbed, developed
the Host ATM Research Platform (HARP) software, which allows IP hosts to
communicate over ATM networks using standard protocols. It is intended to
be a high-quality platform for IP/ATM research.
HARP provides a way for IP hosts to connect to ATM networks. It supports
standard methods of communication using IP over ATM. A host's standard IP
software sends and receives datagrams via a HARP ATM interface. HARP provides
functionality similar to (and typically replaces) vendor-provided ATM device
driver software.
HARP includes full source code, making it possible for researchers to
experiment with different approaches to running IP over ATM. HARP is
self-contained; it requires no other licenses or commercial software packages.
HARP implements support for the IETF Classical IP model for using IP over ATM
networks, including:
o IETF ATMARP address resolution client
o IETF ATMARP address resolution server
o IETF SCSP/ATMARP server
o UNI 3.1 and 3.0 signalling protocols
o Fore Systems's SPANS signalling protocol
What's supported
----------------
The following are supported by HARP 3:
o ATM Host Interfaces
- FORE Systems, Inc. SBA-200 and SBA-200E ATM SBus Adapters
- FORE Systems, Inc. PCA-200E ATM PCI Adapters
- Efficient Networks, Inc. ENI-155p ATM PCI Adapters
o ATM Signalling Protocols
- The ATM Forum UNI 3.1 signalling protocol
- The ATM Forum UNI 3.0 signalling protocol
- The ATM Forum ILMI address registration
- FORE Systems's proprietary SPANS signalling protocol
- Permanent Virtual Channels (PVCs)
o IETF "Classical IP and ARP over ATM" model
- RFC 1483, "Multiprotocol Encapsulation over ATM Adaptation Layer 5"
- RFC 1577, "Classical IP and ARP over ATM"
- RFC 1626, "Default IP MTU for use over ATM AAL5"
- RFC 1755, "ATM Signaling Support for IP over ATM"
- RFC 2225, "Classical IP and ARP over ATM"
- RFC 2334, "Server Cache Synchronization Protocol (SCSP)"
- Internet Draft draft-ietf-ion-scsp-atmarp-00.txt,
"A Distributed ATMARP Service Using SCSP"
o ATM Sockets interface
- The file atm-sockets.txt contains further information
What's not supported
--------------------
The following major features of the above list are not currently supported:
o UNI point-to-multipoint support
o Driver support for Traffic Control/Quality of Service
o SPANS multicast and MPP support
o SPANS signalling using Efficient adapters
