ftruncate(), but without the pad arg.
There are several reasons for this. Consider 'mmap()'. On AMD64, the
function call (and syscall) ABI allow for 6 register arguments. Additional
arguments go on the stack. mmap(2) has 6 arguments. However, the syscall
definition has an extra 'int pad' argument. This pushes it to 7 arguments,
which means one must spill into the memory stack. Since the kernel API
doesn't match userland API, we have a hack in libc - libc/sys/mmap.c.
This implements the userland API by calling __syscall() with an extra
argument and the pad argument, for a total of 8 args. This is all
unnecessary and inconvenient for several things, including the kernel's
syscall handler code which now has to handle merging stack arguments with
register arguments. It is a big deal for certain 3rd party code.
I'm adding libc glue to make the transition totally painless. I had
intended to mark the old syscalls as COMPAT6, but the potential to shoot
your feet by building a new kernel without COMPAT_FREEBSD6 but with a
slighly older userland was too great. For now, they have manual
"freebsd6_" prefixes rather than being COMPAT6. They will go back to
being marked 'COMPAT6' after 7-stable starts.

Also, change the visibility of compat syscalls a slightly. Compat
syscalls were missing from 'syscalls.h' entirely. This additionally adds
them with their compat prefix. eg: SYS_freebsd6_mmap.
Also, the syscalls.c names strings have different prefixes to differentiate
syscalls. Instead of several "old.mmap" strings, there will now be a
"compat.mmap" and "compat6.mmap" etc. Before, both would have had the
same "old.mmap" label.

Postpone calling free() in kern/subr_unit.c:alloc_unr() and nested functions
until the unrhdr mutex is dropped. Save the freed items on the ppfree list
instead, and provide the clean_unrhdrl() and clean_unrhdr() functions to
clean the list.
Call clean_unrhdrl() after devfs_create() calls immediately before
dropping cdev mutex. devfs_create() is the only user of the alloc_unrl()

setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.
Convert all calls to POSIX from historic BSD API:
- unsetenv returns an int.
- putenv takes a char * instead of const char *.
- putenv no longer makes a copy of the input string.
- errno is set appropriately for POSIX. Exceptions involve bad environ
variable and internal initialization code. These both set errno to
EFAULT.
Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit. A few I re-wrote to use setenv()
instead of putenv().

ESTALE), we discard the buffer and return the error back to the
user on the next syscall. This fixes a number of vfs panics and

d_purge method.
destroy_dev_sched() could be used instead from d_close(), to
schedule execution of destroy_dev() in another context. The
destroy_dev_sched_drain() function can be used to drain the scheduled
calls to destroy_dev_sched(). Similarly, drain_dev_clone_events() drains
the events clone to make sure no lingering devices are left after
dev_clone event handler deregistered.
make_dev_credf(MAKEDEV_REF) function should be used from dev_clone
event handlers instead of make_dev()/make_dev_cred() to ensure that created

First, we were never correctly checking for a 24XX Status Type 0
response- that cased us to fall through to evaluate status for
commands as if this were a 2100/2200/2300 Status Type 0 response.
This is *close*, but not quite the same. This has been reported
to be apparent with some wierd lun configuration problems with
some arrays. It became glaringly apparent on sparc64 where none
of the correct byte swap things were done.
Fixing this omission then caused a whole universe shifting debug
cycle of endian issues for the 2400. The manual for 24XX f/w turns
out to be wrong about the endianness of a couple of entities. The
lun and cdb fields for the type 7 request are *not* unconditionally
big endian- they happen to be opposite of whatever the endian of
the current machine type is. Same with the sense data for the
24XX type 0 response.
While we're at it investigate and resolve some NVRAM endian
issues.

- Fix a small race, when a empty data holder is left on the stream
out queue, and both sides do a shutdown, the empty data holder
would prevent us from sending a SHUTDOWN-ACK and at the same time we
never would cleanup the empty holder (since nothing was ever in queue).
We now add a utility function that a) cleans up empty holders and
b) properly determines if there are still pending data chunks on
the stream out wheel.

of Giant in vm_pageout_scan() with VFS_LOCK_GIANT(), I had to eliminate
the acquisition of the vnode interlock before releasing the vm object's
lock because the vnode interlock cannot be held when VFS_LOCK_GIANT() is
performed. Unfortunately, this allows the vnode to be recycled between
the release of the vm object's lock and the vget() on the vnode.
In this revision, I prevent the vnode from being recycled by acquiring
another reference to the vm object and underlying vnode before releasing
the vm object's lock.
This change also addresses another preexisting but trivial problem. By
acquiring another reference to the vm object, I also prevent the vm
object from being recycled. Previously, the "vnodes skipped" counter
could be wrong because if it examined a recycled vm object.
