Improve *access*() parameter name consistency.

The current code mixes the use of `flags' and `mode'. This is a bit
confusing, since the faccessat() function as a `flag' parameter to store
the AT_ flag.

Make this less confusing by using the same name as used in the POSIX
specification -- `amode'.

Remove unused LIBCOMPAT keyword from syscalls.master.

Burn TTY ioctl bridges in compat layers.

I really don't want any pieces of code to include ioctl_compat.h, so let
the ibcs2 and svr4 compat leave sgtty alone. If they want to support
sgtty, they should emulate it on top of termios, not sgtty.

The code has been marked with BURN_BRIDGES for a long time. ibcs2 and
svr4 are not really popular pieces of code anyway.

Now that all system calls are MPSAFE, retire the SYF_MPSAFE flag used to
mark system calls as being MPSAFE:
- Stop conditionally acquiring Giant around system call invocations.
- Remove all of the 'M' prefixes from the master system call files.
- Remove support for the 'M' prefix from the script that generates the
syscall-related files from the master system call files.
- Don't explicitly set SYF_MPSAFE when registering nfssvc.

Somewhat surprisingly, ibcs2_ioctl() is MPSAFE as it is without needing any
further fixes.

Mark ibcs2_mount() (just returns EINVAL) and ibcs2_umount() (just calls
unmount(2)) MPSAFE.

- Add conditional VFS Giant locking to getdents_common() (linux ABIs),
ibcs2_getdents(), ibcs2_read(), ogetdirentries(), svr4_sys_getdents(),
and svr4_sys_getdents64() similar to that in getdirentries().
- Mark ibcs2_getdents(), ibcs2_read(), linux_getdents(), linux_getdents64(),
linux_readdir(), ogetdirentries(), svr4_sys_getdents(), and
svr4_sys_getdents64() MPSAFE.

Mark ibcs2_msgsys(), ibcs2_semsys(), and ibcs2_shmsys() MPSAFE.

Use the regular poll(2) function to implement poll(2) for the IBCS2 compat
ABI as FreeBSD's poll(2) is ABI compatible. The ibcs2_poll() function
attempted to implement poll(2) using a wrapper around select(2). Besides
being somewhat ugly, it also had at least one bug in that instead of
allocating complete fdset's on the stack via the stackgap it just allocated
pointers to fdsets.

Assign audit event identifiers to ibcs2 system calls.

Make a pass through all the compat ABIs sychronizing the MP safe flags
with the master syscall table as well as marking several ABI wrapper
functions safe.

MFC after: 1 week

Introduce a new field in the syscalls.master file format to hold the
audit event identifier associated with each system call, which will
be stored by makesyscalls.sh in the sy_auevent field of struct sysent.
For now, default the audit identifier on all system calls to AUE_NULL,
but in the near future, other BSM event identifiers will be used. The
mapping of system calls to event identifiers is many:one due to
multiple system calls that map to the same end functionality across
compatibility wrappers, ABI wrappers, etc.

Fix the ABI wrappers to use kern_fcntl() rather than calling fcntl()
directly. This removes a few more users of the stackgap and also marks
the syscalls using these wrappers MP safe where appropriate.

ibcs2_wait() now MPSAFE.

Submitted by: Dan Nelson <dnelson@allantgroup.com>

Sync up MP safe flags with global syscalls.master. This includes write(),
close(), getpid(), ibcs2_setuid(), getuid(), ptrace(), ibcs2_pause(),
ibcs2_nice(), ibcs2_kill(), ibcs2_pgrpsys(), dup(), pipe(), ibcs2_setgid(),
getgid(), umask(), and sigreturn().

The following compat syscalls are now mpsafe: linux_getrlimit(),
linux_setrlimit(), linux_old_getrlimit(), osf1_getrlimit(),
osf1_setrlimit(), svr4_sys_ulimit(), svr4_sys_setrlimit(),
svr4_sys_getrlimit(), svr4_sys_setrlimit64(), svr4_sys_getrlimit64(),
ibcs2_sysconf(), and ibcs2_ulimit().

Oops, remove references to namespc column in comment (I'm not going to
bother regenerating after this)

GC namespc column and unwrap long lines that now fit.

Synchronize syscalls.master(s) with recent Giant pushdown work

Sigh. Fix SYS_exit problems. I misunderstood the significance of these
trailing options.

Change the 'exit()' system call to 'sys_exit()'. This avoids overlapping
gcc's internal exit() prototypes and the (futile) hackery that we did to
try and avoid warnings. main() was renamed for similar reasons.
Remove an exit related hack from makesyscalls.sh.

Fixed the return type and args struct tag for exit(). They were wrong in
all emulators. These entries were unused, so the bug had no effect, but
the the args struct tag will be used to calculate sy_nargs correctly.

$Id$ -> $FreeBSD$

Removed unused #includes.

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Oops. forgot to remove #include "opt_sysvipc.h"

Remove the #ifdef SYSVSHM etc. Always call the functions, some stubs
are about to go in. This is to fix the problem with the ibcs2 and linux
lkm's not being able to call the sysv ipc functions unless the build is
modified.

Convert SYSV IPC to new-style options. (I hope I got everything...)
The LKMs will need an extra file, to come later.

Remove old files no longer needed.
Add new files created for emulator.
Modify NetBSD import to work with FreeBSD and add new features and
code. The complete emulator is essentially a combination of work/code
implemented by Sean Eric Fagan, Soren Schmidt, Scott Bartram, and myself,
Steven Wallace.

Features of this new emulator system include:

o "clean" code, including strict prototyping.
o Auto-generation of ibcs2 system calls, xenix system calls, isc system
calls. Generation includes system tables, structure definitions,
and prototyping of function calls.
o ibcs2 emulator does not rely on any COMPAT_43 system calls.
o embedded socksys support
o ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel
o alternate /emul/ibcs2 namespace searched first for files in ibcs2
system. Usefull to keep sysv libraries, binaries in /emul/ibcs2.
o many other finer details and functions fixed or implemented.

This commit was generated by cvs2svn to compensate for changes in r11394,
which included commits to RCS files with non-trunk default branches.

Import of original NetBSD's ibcs2 emulator sources by Scott Bartram,
which is used as a basis for a more complete and cleaner ibcs2 emulator.
(snapshot about May 1995 with a few files from September 1995)

Some files and code from old emulator still remains.
New files, features, and changes have been implemented by myself,
which will be shown in following commits.
