f3d5a9dc61 Reduce compiler/libraries/headers cases to only two
1. ack, a.out, minix headers (moved to /usr/include.ack),
	   minix libc
	2. gcc/clang, elf, netbsd headers (moved to /usr/include),
	   netbsd libc (moved to /usr/lib)

So this obsoletes the /usr/netbsd hierarchy.

No special invocation for netbsd libc necessary - it's always used
for gcc/clang.

230b7775fe changes for detecting and building for clang/binutils elf
and minor fixes:
 . add ack/clean target to lib, 'unify' clean target
 . add includes as library dependency
 . mk: exclude warning options clang doesn't have in non-gcc
 . set -e in lib/*.sh build files
 . clang compile error circumvention (disable NOASSERTS for release builds)

6567e50a6f mk scripts: add flag for compiling with nbsd libc.
This patch changes the system mk scripts to enable compilation
of programs using the BSD make system to compile with the new
libc.

In details, it does the following:

- it always defines the __MINIX make variable. This can be used,
 in porting applications, to specialize Makefiles for Minix.

 - If the environment variable NBSD is set to something different
  than 'no' and if the compiler is not ack, set NBSD_LIBC to 'yes'.
  This will set the destination lib directory to '/usr/netbsd/lib' 
  and set up CPPFLAGS and LDFLAGS to use new libc's includes and
  library directory.

287fee89cb add NOASSERTS make flag that disables assert()s (NDEBUG=1).
. made some checks in vfs/vnode.c also respond to NDEBUG=1.
  . turned on in release builds

62c666566e SMP - We boot APs
- kernel detects CPUs by searching ACPI tables for local apic nodes

- each CPU has its own TSS that points to its own stack. All cpus boot
  on the same boot stack (in sequence) but switch to its private stack
  as soon as they can.

- final booting code in main() placed in bsp_finish_booting() which is
  executed only after the BSP switches to its final stack

- apic functions to send startup interrupts

- assembler functions to handle CPU features not needed for single cpu
  mode like memory barries, HT detection etc.

- new files kernel/smp.[ch], kernel/arch/i386/arch_smp.c and
  kernel/arch/i386/include/arch_smp.h

- 16-bit trampoline code for the APs. It is executed by each AP after
  receiving startup IPIs it brings up the CPUs to 32bit mode and let
  them spin in an infinite loop so they don't do any damage.

- implementation of kernel spinlock

- CONFIG_SMP and CONFIG_MAX_CPUS set by the build system
