5d4cf83257 when loading interpreter: check its vnode type, check its mount point 
for NOEXEC and NOSUID, and make sure the interpreter file is executable.
The mount point checks are done because, even though the interpreter
is not the program being 'executed', code from the interpreter is being
executed, and so the mount point's flags should be respected.

2da166f660 Fix p_nice vs. NZERO code. 
Change NZERO to 20 to always make p_nice positive.
On Christos' suggestion make p_nice explicitly u_char.

COMPAT_ULTRIX is included, and of EXEC_ELF32 when COMPAT_LINUX and/or
COMPAT_SVR4 is included.

60b9a20b61 initialize vnode_free_list and mountlist at compile time with the new 
queue.h list/queue head initializer macros.  mountlist was converted so
that panics (or other reboots) early on in kernel startup don't cause
sys_sync() to croak.  vnode_free_list was converted because it was nearby.

0e097578a2 add and use a machine-dependent header, which currently defines some 
macros to use to remove #ifdefs from the machine ID case check.
Eventually, these headers will contain other information, e.g.
machine-dependent relocation information, etc.

da17295d91 Calling shmdt(2) before calling shmat(2) would crash the system because 
p->p_vmspace->vm_shm would be NULL. Protected the rest of the cases where
that might happen too. This was the reason why sunxdoom would panic the
system in SVR4 emulation.

a9ef8aef84 This fixes a nasty little bug where traceroute (and other raw-ip sending 
programs which attach their own header) can crash the machine.  The problem
in this case was:
	a variable "space" was set to the total data to copy,
	len was used to remember how much to copy in this chunk (mbuf),
	in one case, len = min(MCLBYTES - max_hdr, resid) but
		size -= MCLBYTES;
	 instead of
		size -= len;

Note that userland programs can still crash the machine by providing
bogus data in the ip->ip_len field I suspect.  I haven't verified this,
but will soon be doing so and applying a fix of some sort.  Probably
clamping the ip->ip_len value to the true packet size will be ok.

a boot string for firmware that can do this, such as the SPARC and
the sun3 models.  It is currently silently ignored on all other
hardware now, however.  The MD function "boot()" has been changed to
also take a char *.
