c03313d48c Simplify and correct OSF/1 signal handling.
- No signal translation is needed.  Our signals match the OSF/1 signals
- an OSF/1 sigset_t is 64 bits.  Make certain to use all 64-bits of it.
  We'd previously only used the lower 32 bits.   This was mostly harmless
  as I don't know of an OSF/1 apps which use any signals > 31.  However,
  the alpha Linux ABI uses the osf/1 signal routines and threaded linux
  apps tyically use signals 32 and 33 to comminicate with the manager
  thread, so it is important we preserve the upper 32-bits.

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.
