7a8e4b4bc4 Two small changes to the ELF exec code: 
(1) ELFNAME(load_file)() now takes a pointer to the entry point
offset, instead of taking a pointer to the entry point itself.  This
allows proper adjustment of the ultimate entry point at a higher level
if the object containing the entry point is moved before the exec is
finished.

(2) Introduce VMCMD_FIXED, which means the address at which a given
vmcmd describes a mapping is fixed (ie, should not be moved).  Don't
set this for entries pertaining to ld.so.

Also some minor comment/whitespace tweaks.

d2027d4d00 Fix _lwp_wakeup() so that it stands a chance of working (although it 
turns out to be insufficent for signal-level interruption of system
calls. guess we need _lwp_kill(), ugh).

892c25bc38 Fix proc_representative_lwp(); a closing brace was in the wrong place, 
which means it would return the first non-dead LWP.

Pointed out by Stephan Uphoff.

5e14aa69a8 There's a locking order issue with the scheduler and the callwheel locks 
as ltsleep() may call callout_reset() with the scheduler lock held.
So, prevent interrupts that may take the scheduler lock while holding
the callwheel lock.

01ca174f62 Call exit_lwps() from exit1() if there is more than one LWP (as 
recorded by p_nlwps) *or* if the process was a SA process. Since
cached SA LWPs aren't counted in p_nlwps, it was possible for
them to not be cleaned up and remain on the alllwp list, pointing to a
dead proc.

a3ff3a3038 Bump daddr_t to 64 bits. Replace it with int32_t in all places where 
it was used on-disk, so that on-disk formats remain the same.
Remove ufs_daddr_t and ufs_lbn_t for the time being.
