Add (but don't activate) code to use the new stack facility when running threads, (specifically the linux threads support). This allows people to use both linux compiled linuxthreads, and also the native FreeBSD linux-threads port. The code is conditional on VM_STACK.

Nitpicking and dusting performed on a train. Removes trivial warnings 1998-10-25T17:44:59+00:00 Poul-Henning Kamp phk@FreeBSD.org 1998-10-25T17:44:59+00:00 f5ef029e9226c3849bdd1100b4ffe4eb60fec3d0 about unused variables, labels and other lint.

Fixed two potentially serious classes of bugs: 1998-10-13T08:24:45+00:00 David Greenman dg@FreeBSD.org 1998-10-13T08:24:45+00:00 6cde7a165f154ed47b58fc42d6d2041e18384680 1) The vnode pager wasn't properly tracking the file size due to "size" being page rounded in some cases and not in others. This sometimes resulted in corrupted files. First noticed by Terry Lambert. Fixed by changing the "size" pager_alloc parameter to be a 64bit byte value (as opposed to a 32bit page index) and changing the pagers and their callers to deal with this properly. 2) Fixed a bogus type cast in round_page() and trunc_page() that caused some 64bit offsets and sizes to be scrambled. Removing the cast required adding casts at a few dozen callers. There may be problems with other bogus casts in close-by macros. A quick check seemed to indicate that those were okay, however.
