int. Massively reduced kernel lint, causes no harm. Discussed

6cb3157ebe Add defines for the rest of fasttraps as defined on Solaris8/i386. For 
documentation purposes only (though CLOCK_SETTIME a.k.a T_GETHRESTIME
shouldn't be too hard to implement).

e727e3f180 Split elf32 vs. elf64 handling in loadfile(), including support for 
each separately and explicitly.  BOOT_ELF is now BOOT_ELF32 and
BOOT_ELF64, and ELFSIZE should no longer be defined in loadfile_machdep.h.

5d461f21ee Update freebsd_sigcontext to what FreeBSD currently uses, and save/restore 
%fs/%gs as appropriate.

XXX Note that the new sigcontext uses the new sigset_t instead of old
int sc_mask. The new FreeBSD sigcontext doesn't contain any backward
compatibility sc_mask, so basically old FreeBSD application making
use of sigcontext are hosed. This can't be fixed in NetBSD compat code.

cbc00e701a Until early last year, the i386 port had 256M of kvm, and the max. 
amount of kvm used for buffers was set at 70%, some 188M. Then
the total amount of kvm became 1G, and the amount for buffers
thus became some 716M. This is really too much, and some
device drivers want to map quite a bit of kvm these days.

So, cap it at 384M, which gives each buffer a little over 8k (the
default FFS blocksize) physical in an 1G physram configuration.

0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

edea1a2c17 Make it possible to query each battery individually by making the 
APM_IOC_GETPOWER ioctl read/write. Setting the batteryid in the passed
structure returns the data for just that battery. The old ioctl
remains for binary compatibility but has been renamed.

Itojun already did the hard work -- I just added a couple of lines.

7e7d262c34 Add %fs/%gs to trap frame and save/restore them on 
trap/interrupt/syscall entry from userspace.

Remove special-case "by hand" validation of fs/gs register values as
well as special handling of them in various signal handling paths.

Now, like %ds and %es, they are validated by the hardware on return to
userland.

This paves the way for the use of %fs for per-cpu data on
multiprocessor systems, and fixes an otherwise difficult-to-fix
interaction between threads/clone(2) and USER_LDT.

Discussed in advance with Frank van der Linden.
