the syscalls using these wrappers MP safe where appropriate.

- improve sysinfo(2) syscall;
- add dummy fadvise64(2) syscall;
- add dummy *xattr(2) family of syscalls;
- add protos for the syscalls 222-225, 238-249 and 253-267;
- add exit_group(2) syscall, which is currently just wired to exit(2).

fchown is also mapped to the native fchown, give the new one
type NODEF.

in the FreeBSD kernel. Therefore, map the syscall directly to
getpgid().

1. establish type independence for ease in porting and,
2. provide a visual queue as to which syscalls have proper
prototypes to further cleanup the i386/alpha split.
Linuxulator types are prefixed by 'l_'. void and char have not
been "virtualized".
o Remove dummy functions for syscalls that are now truely
unimplemented.
o Rename syscalls so they match the names used in the Linux kernel.
Also, provide more accurate prototypes. This generally improves
cross-referencing and reduces head-scratching.
o Provide seperate implementations for the 16-bit uid_t and gid_t
based syscalls as Linux used to have. The new 32-bit uid_t and
gid_t based syscalls now map to their FreeBSD equivalents.
o Fix the linux_ipc syscall so that it doesn't force the shm*, sem*
and msg* syscalls to have the same syscall. The prototypes for
these syscalls now match the those used on Alpha. While here,
add the same kludge for MSGRCV as is present in the Linux kernel.
o Implement the following syscalls:
linux_stat64, linux_lstat64 and linux_fstat64
linux_sysctl
o Added syscalls numbered 198 - 221. This include:
- the 32-bit uid_t and gid_t bases syscalls
- 64-bit file offset/size based syscalls
and associated user-level signal trampoline glue.
Without this patch, an SA_SIGINFO style handler can be installed by a linux
app, but if the handler accesses its sip argument, it will get a garbage
pointer and likely segfault.
We currently supply a valid pointer, but its contents are mainly
garbage. Filling this in properly is future work.
This is the second of 3 commits that will get IBM's JDK 1.3 working with

syscalls including exit(). These entries were unused, so the bugs had no
effect, but the the args struct tag will be used to calculate sy_nargs
correctly. exit() was wrong in all emulators.
-----------------------------
The compatibility code and/or emulators have been updated:
iBCS2 now mostly uses the older syscalls. SVR4 now properly
handles all signals. This has been achieved by using the
new sigset_t throughout the emulator. The Linuxulator has
been severely updated. Internally the new Linux sigset_t is
made the default. These are then mapped to and from the
new FreeBSD sigset_t.
Also, rt_sigsuspend has been implemented in the Linuxulator.
Implementing this syscall basicly caused all this sigset_t
changing in the first place and the syscall has been used
throughout the change as a means for testing. It basicly is
too much work to undo the implementation so that it can
later be added again.
A special note on the use of sv_sigtbl and sv_sigsize in
struct sysentvec:
Every signal larger than sv_sigsize is not translated and is
passed on to the signal handler unmodified. Signals in the
range 1 upto and including sv_sigsize are translated.
The rationale is that only the system defined signals need to
be translated.
The emulators also have been updated so that the translation
tables are only indexed for valid (system defined) signals.
This change also fixes the translation bug already in the
SVR4 emulator.
know if and when an unimplemented or obsoleted syscall is being used. Make the
message more end-user friendly.
And as long as we're here, rename some unimplemeted syscalls (linux_phys ->
linux_umount2, linux_vm86 -> linux_vm86old, linux_new_vm86 -> linux_vm86).
Change prototype for linux_newuname from `struct linux_newuname_t *' into
`struct linux_new_utsname *'. This change is reflected in linux.h and
linux_misc.c.
Lastly, make line-continuation and indentation more uniform.
