- We shouldn't allocate MAXPATHLEN from the stack.
- Don't copy the pathbuf into kernel space unless we're systracing.

fix an issue when scripts are exec'd under systrace where
the argv[0] would be normalized, and hence break scripts
that depend on how they were called.

this fixes an issue in the ports builds.

a few fixes to systrace

- add an exec message so that whenever a set-uid/gid process
exec's a new image which we may control, the exec does not
go by unnoticed.

- take special care to check for

- take special care to check for P_SUGIDEXEC as well as
P_SUGID, corresponding to the same changes that were made in
the ptrace code a while ago

We can jump to the fail: label before shellargp is initialized.
Make sure that we don't free random memory when that happens.

Change the vnode locking in exec to not keep the vnode locked almost all
the time.

This could lead to problems when a process wants to do an exec on the same
vnode it's being run from and needs to copy in arguments from an uncached
page in the data segment. When that happens uvm detects a vnode deadlock
and returns an error causing execve() return EFAULT.

This fixes the regress test in regress/sys/kern/exec_self

Also, initialize scriptvp early in exec_script because it could be
used uninitialized in a failure case.

- every new fd created by falloc() is marked as larval and should not be used
any anyone. Every caller of falloc matures the fd when it's usable.
- Since every lookup in the fd table must now check this flag and all of
them do the same thing, move all the necessary checks into a function -
fd_getfile.

ifdef FOO inside an ifdef FOO feels like overkill.

Don't use MALLOC/FREE on variable sized allocations.

remove superflous declaration of vnops, it's now in <sys/file.h>

force FDSCRIPTS after include files are pulled in

panic prints a newline for you, don't do it in the panic string

Updates for VFS Lite 2 + soft update.

back out vfs lite2 till after 2.2
