84e40f5627 The handle for the kernel is common. With this fix, ELF kernels can load
a.out kld modules, and a.out kernels can load ELF kld modules.

e91a7f30cf Initialize the a.out kld loader after elf, so that elf gets first shot at
a kldload attempt.

adbb7dbee6 Updates for KLD backends.
- symbol_values checks that the symbol is indeed belonging to the
   correct symbol and string table pairs before looking up. (since there
   could be many pairs, and KLD/DDB need to find out).
 - different ops for files versus preload modules - the unload mechanism
   is different.  (a preloaded module has to be deleted on unload since
   the in-core image is tainted by relocation and variables used)
 - Do not build an a.out kernel module if we're running on an elf
   kernel. :-)  Note that it should theoretically be possible to
   mix a.out and elf KLD modules providing -mno-underscores was used
   to compile it, or some other symbol conversion takes place.
 - Support preload modules (even though /boot/loader doesn't yet)
 - Search the module path when loading files.

86a14a7a0a Use [u]intptr_t instead of [u_]long for casts between pointers and
integers.  Don't forget to cast to (void *) as well.

a2c99e3e72 Modify the internal interfaces to the kernel linker to make it possible
for DDB to use its symbol tables.

a23d65bfc8 Cast pointers to uintptr_t/intptr_t instead of to u_long/long,
respectively.  Most of the longs should probably have been
u_longs, but this changes is just to prevent warnings about
casts between pointers and integers of different sizes, not
to fix poorly chosen types.

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

f173e80c8b make a couple functions static...
also change module_register_static to module_register_init as this
function initalizes the module for both dynamic and static modules...

cea6c86c11 This is the kernel linker. To use it, you will first need to apply
the patches in freefall:/home/dfr/ld.diffs to your ld sources and set
BINFORMAT to aoutkld when linking the kernel.

Library changes and userland utilities will appear in a later commit.
