73e50f111b Do like the non-__OPTIMIZE_SIZE__ variant, and compile memset() unless 
BZERO is defined, instead of requiring MEMSET to be defined.

Avoids violating the principle of least astonishment, and also fixes
the build of stand/ and kernels for (at least) alpha.

2ba84f0f9e Add tuned powerpc assembler written by IBM and released under a 3-clause 
BSD Lisc as part of the perflib project.
http://sourceforge.net/projects/ppcperflib/

Tested the new functions with microbenchmarks on a number of different
CPU types, and  found that most cpus either benefited greatly, or were
unaffected.  Primarily G4 CPU's were unaffected, and all others showed
speedups.  My 7044 (POWER3) went from a 70.6 to a 73.2 (thats good) in
bytebench with a complete release built with these.  Also passed
regression tests.

22ac6fc0fb Add x86emu for in-kernel use. This is a 386 real mode emulator that can 
be used to run ROM code inside the kernel without having to setup vm86
and without having a x86 CPU at hand.

This code was originally written by SciTech and released under MIT/X11
license for XFree86. It has been refactored be less than half of the
original size, the compiled code being around a third of the former
size. The interface was changed to be a real library, e.g. no global
variables are used.

2a0ce8a57f Improve consistency between <sys/bswap.h> and what's actually 
defined by the C library for the various m68k ports by borrowing
some #ifs from the i386 port.

Also, align sun2 with the other m68k ports as to whether they
define __bswap{16,32} or bswap{16,32} in their C library (all
now define the __ variants).

This should make the m68k ports build sys/rump again, except
for sun2 which hits another problem later on.

e835604c26 libprop is currently using a recursive parser. While this is fine for 
userland, deeply nested arrays and dictionaries can easily overflow
the kernel stack and thereby force a panic.

Fix the internalizer and prop_object_release to use a separate call
stack and alter the dictionary and array handling to not recurse on
the C stack. The default stack has an inline depth of 16 elements,
which should keep the overhead reasonable.

This issue was found by Pavel Cahyna and Jachym Holecek.

Additionally add a limit for prop_object_copyin_ioctl to prevent user
programs from temporary allocating unbound amount of kernel memory.
Allow malloc to fail so that tight loops of userland processes can't
force panics by exhausting the kernel map.

Tested with the sample exploit of Jachym, his test suite and reviewed
by himself (initial patch), Christos Zoulas and Jason Thorpe.

bb54157110 Add a comment to explain how the value for uaddr is chosen. Maybe uvm_mmap 
should do that instead of sys_mmap...

00fbe2b725 In _prop_object_copyout_ioctl, uaddr was not initialised, although it is 
used by uvm_mmap() as a hint for the virtual address to map memory to.  As
a consequence, it tended to fail a lot on some architectures.

We cannot use 0, so instead use the value that would have been used if we
were calling mmap(2) with 0 as the first argument.

Fixes PR#34639 by xtraeme@.

e3361bb265 Add strsep(3) to libkern. 
To avoid code duplication, move strsep.c to the kernel/userland
common files.

Soon I will commit source-address selection (options IPSELSRC).
It will use strsep(3).

80b96f1aa4 Add include of <sys/param.h>, to allow vax kernels to build again. 
For vax, this causes <machine/macros.h> to be included and the
redefine of memset() to take effect.

088af57adf Do the used/unused dance under #ifdef KERNEL too. Prevents mcount 
from being optimized away when compiling sh3 kernels with profiling
enabled (gcc doesn't see that __mcount, which is written in asm,
refers to it).

26d4f90430 - Add prop_dictionary_all_keys(). Takes a snapshot of a dictionary's 
keys and returns them in an array.  This effectively allows a caller
  to mutate a dictionary while iterating over it (really, you iterate
  over the array of keys instead of the dictionary itself).
- Add a slew of utility functions that make it more convenient (in some
  circumstances, anyway) to get/set values in a dictionary.

637106d04b Make it compile with -Wextra on big endian machines (at lest the #if in the 
definition of struct rb_ndoe on the endianess is the only explanation I have
why nobody complained about this on i386 - I don't understand why it makes a
difference for gcc though)
