Attempt to fix the mess.

Stubs for future development of linux compat architechtures.

Always clear FUTEX_PRIVATE_FLAG for Linux processes. NetBSD-native futexes
exist in different namespace depending on FUTEX_PRIVATE_FLAG. This appears
not to be the case in Linux, and some futex users will mix private and non-
private ops on the same futex object. Provide a convenience wrapper that
puts this logic in one place witn a comment explaining why.

While here, move the Linux futex wrapper out of its own file and plop
it in linux_misc.c, which is where it lives in the linux32 module.

Add fadvise64 and fadvise64_64 syscalls to compat_linux and compat_linux32.

branches: 1.6.2;
many changes for COMPAT_LINUX:
- update the linux syscall table for each platform.
- support new-style (NPTL) linux pthreads on all platforms.
clone() with CLONE_THREAD uses 1 process with many LWPs
instead of separate processes.
- move the contents of sys__lwp_setprivate() into a new
lwp_setprivate() and use that everywhere.
- update linux_release[] and linux32_release[] to "2.6.18".
- adjust placement of emul fork/exec/exit hooks as needed
and adjust other emul code to match.
- convert all struct emul definitions to use named initializers.
- change the pid allocator to allow multiple pids to refer to the same proc.
- remove a few fields from struct proc that are no longer needed.
- disable the non-functional "vdso" code in linux32/amd64,
glibc works fine without it.
- fix a race in the futex code where we could miss a wakeup after
a requeue operation.
- redo futex locking to be a little more efficient.

Define linux_usertrap function, and set it in struct emul. For all

For amd64, it implements vsyscalls through cheating: if the faulting
address is in the vsyscall area (which is statically known on Linux/amd64),
and the intruction pointer is too, it must have been a vsyscall. In that
case, retrieve the return address from the user stack, fix up %rip and
%rsp, and just execute the normal system call. It will return as if
the vsyscall has been executed.

Dynamic sysctl.

Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.

Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded. Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.

All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.

PS - I'm sorry, but there's a distinct lack of documentation at the
moment. I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

Merge the nathanw_sa branch.

Don't include <sys/map.h>.

Add kernel support for having userland provide the signal trampoline:

* struct sigacts gets a new sigact_sigdesc structure, which has the
sigaction and the trampoline/version. Version 0 means "legacy kernel
provided trampoline". Other versions are coordinated with machine-
dependent code in libc.
* sigaction1() grows two more arguments -- the trampoline pointer and
the trampoline version.
* A new __sigaction_sigtramp() system call is provided to register a
trampoline along with a signal handler.
* The handler is no longer passed to sensig() functions. Instead,
sendsig() looks up the handler by peeking in the sigacts for the
process getting the signal (since it has to look in there for the
trampoline anyway).
* Native sendsig() functions now select the appropriate trampoline and
its arguments based on the trampoline version in the sigacts.

Changes to libc to use the new facility will be checked in later. Kernel
version not bumped; we will ride the 1.6C bump made recently.

Regen: Use linux_sys_{g,s}setrlimit, remove linux_sys_ugetrlimit since
linux/mips doesn't seem to have one.

Regen

- add a real linux_sys___sysctl because the mib numbers are different.
implement only the kernel version getting entries.
- make the signal conversion functions consistent; dest is arg 1.
- make linux_fakedev deal with block and char devices differently.
- add linux_sys_ugetrlimit, and flesh out the regular get/setrlimit so
that they work properly.
- add linux_mmap2 [untested].
- bump kernel to 2.4.18, and make the date be valentine's day :-)
- linux_sys_*stat64 family was totally busted. Fix it.
