b5eb64d6f0 Pre-KSE/M3 commit.
this is a low-functionality change that changes the kernel to access the main
thread of a process via the linked list of threads rather than
assuming that it is embedded in the process. It IS still embeded there
but remove all teh code that assumes that in preparation for the next commit
which will actually move it out.

e028603b7e With Alfred's permission, remove vm_mtx in favor of a fine-grained approach
(this commit is just the first stage).  Also add various GIANT_ macros to
formalize the removal of Giant, making it easy to test in a more piecemeal
fashion. These macros will allow us to test fine-grained locks to a degree
before removing Giant, and also after, and to remove Giant in a piecemeal
fashion via sysctl's on those subsystems which the authors believe can
operate without Giant.

66b81f3469 Apparently, the vm_mtx must be held around vm_map_find(). I'm assuming
that it needn't be held around vm_mmap() since vm_mmap() itself aquires
it.

14c37370d1 exec_osf1_imgact() should return -1 for non OSF1/ECOFF binaries, it should
not return ENOEXEC.  This is because image activators should return -1 if they
don't claim an image. They should return ENOEXEC if they do claim it,
but cannot load it due to sime problem with the image.   This bug was
preventing static compilation of the osf/1 module.  I'm surprised it
did not cause more problems.

1b39d5d377 Finally add the Alpha OSF/1 compat code. I will add it to the
sys/modules Makefile after completing a buildworld.

History:

The bulk of this code was obtained from NetBSD approximately one year
ago (I have taken care to preserve the original NetBSD copyrights and
I thank the authors for their work.) At that time, the OSF/1 code was
what was left over from their initial bootstrapping off of OSF/1 and
did not provide support for executing shared binaries.

I have independently added support for shared libraries, and support
for some of the more obscure system calls.  This code has been
available for testing and comment since January of 1999 and running on
production machines here at Duke since April.

Known working applications include:

- Netscape (all versions I've tried)
- Mathematica 3.0.2
- Splus 3.4
- ArcInfo 7.1
- Matlab (version unknown)
- SimOS
- Atom instrumented binaries (built on a real OSF/1 system)

Applications which are known not to work:

- All applications linking to libmach
- Adobe Acrobat  (uses libmach)

This has been tested with applications running against shared
libraries from OSF/1 (aka Tru64) 4.0D and 4.0F.
