Fix a race condition between kern_wait() and thread_stopped().
Problem is in kern_wait(), parent process steps through children list,
once a child process is skipped, and later even if the child is stopped,
parent process still sleeps in msleep(), the race happens if parent
masked SIGCHLD.

Call g_waitidle() instead of GEOM using the root_mount_hold() KPI.
GEOM could (and will) get events as a result of drivers coming in
late so a one-shot method is not good enough for GEOM.
Break out the definition of bus_space_{tag,handle}_t and a few other types
into _bus.h to help with name space polution from including all of bus.h.
In a few days, I'll commit changes to the MI code to take advantage of thse
sepration (after I've made sure that these changes don't break anything in
the main tree, I've tested in my trees, but you never know...).

Introduce p_canwait() and MAC Framework and MAC Policy entry points
mac_check_proc_wait(), which control the ability to wait4() specific
processes. This permits MAC policies to limit information flow from
children that have changed label, although has to be handled carefully
due to common programming expectations regarding the behavior of
wait4(). The cr_seeotheruids() check in p_canwait() is #if 0'd for
this reason.
The mac_stub and mac_test policies are updated to reflect these new
entry points.
Fix newer Xircom CBE2-100 cards that were reporting
dc0: MII without any PHY!
We have to enable the connection to the MII first. Doing so fixes the
problem cards without breaking the older, working cards.

Add a sysctl that returns the full path of a process' text file.
This information is needed by things like `gdb -p' and Sun's javac,
and previously it could only be obtained via procfs
Portability enhancement: MS Windows won't restore metadata if the file
is still open, so close the file as soon as we've written the
file contents, before we attempt to restore metadata.
A number of fixes to the autoconf-generated build system. In
particular, acl support is no longer enabled on FreeBSD 4, acl support
should be correctly enabled on Linux, dirent.d_namlen should be
correctly detected on platforms that support it.

Style and minor changes:
- Merge esp_sbus.c rev. 1.31 from NetBSD: nuke trailing whitespace.
Rev. 1.28 and 1.30 were already merged, 1.29 is not relevant for FreeBSD.
- Remove unused headers.
- Use BUS_PROBE_DEFAULT.
- Use __func__ instead of hardcoded function names in error messages.
- Correct some comments.
- Correct some function declarations to match their prototypes.
- Some style(9) fixes (don't use function calls in initializers; indentation).
- Zero the allocated structs to avoid problems with uninitialized members.
- Remove the ifdef'ed out SBus interrupt priority code and the hook for
ncr53c9x_reset(), remove the unused SBus interrupt priority member from
esp_softc. On FreeBSD setting the SBus interrupt priority is entirely done
in sbus(4) and the reset function isn't even really used in NetBSD.
- s,dma,DMA, in comments.
- Make the code fit in 80 columns.

Style and minor changes:
- Merge lsi64854.c rev. 1.25 from NetBSD: nuke trailing whitespace.
- Update NetBSD RCS IDs according to what was actually already merged.
- Remove dv_name from the lsi64854_softc and use device_printf() instead.
- Use __func__ instead of hardcoded function names in error messages.
- Use ulmin() instead of min() for comparing the DMA sizes as the values
involved actually are represented by 64bit unsigned instead of 32bit
unsigned. As far as I can't tell this doesn't make a difference in
practice though.
- Some style(9) fixes (mainly indentation).
- Remove unnecessary braces.
Support path-rewriting options (including --strip-components) for both
extraction and creation. While I'm here, fix a bug reported by Garrett
Wollman: when stripping the leading '/' from the path "/", don't produce
an entry with an empty name; produce "." instead.
NFS write gathering defers execution of NFS server write requests to wait
to see if additional write requests will arrive that can be coalesced and
clustered with earlier ones. When doing so, it must determine whether
the two requests are made by credentials with the same access writes, so
as not to coalesce improperly. NFSW_SAMECRED() implements a test of two
credentials using a binary compare.
Replace NFSW_SAMECRED() macro with nfsrv_samecred() function, which is
aware of the contents and layout of a struct ucred, rather than a simple
binary compare. While the binary compare works when ucred is simply a
zero'd and embedded 'struct ucred' in the NFS descriptor, it will work
less well when the ucred associated with an NFS descriptor is "real", so
has defined and populated reference count, mutex, etc.
De-dma the uaudio <-> pcm bridge. We were not capable of doing DMA from
this buffer anyway so the constraint that it had to be DMA capable only
caused pain when devices failed to aquire the memory. Use a regular
malloc instead with sndbuf_setup.

Re-commit the following changes which were committed to these files
at their old location in sys/dev/esp after they were repo-copied to

- Split the bus probe function into a bus probe and a bus attach function
with the attaching of the children done in the bus attach function like
it's supposed to be.
- In the bus probe nomatch function print the resources of the children
like it's done in the other sparc64 specific bus drivers.
- For the clock frequency IVAR use the per-child values and fall back to
the bus default in case a child doesn't have the respective property
instead of always using the bus default so a child driver doesn't need
to obtain the per-child value itself (see also the commit message of
sys/dev/esp/esp_sbus.c rev. 1.7).
- Add support for pass-through allocations. The comment preceding
sbus_alloc_resource() wasn't quite correct, we need to support pass-
through allocations for the 'espdma' and 'ledma' (pseudo-)busses which
hang off of the SBus in Ultra 1 machines. There can also be actual
bridges like the SBus-to-PCMCIA bridge on the SBus and the XBox (SBus
extension box) probably also involves one.

Some clean-up announced in rev. 1.31:
- Use auto-generated typedefs for the prototypes of the device interface
functions.
- Style(9) fixes (mainly don't use function calls in initializers).
- Use __func__ instead of hardcoded function names in error messages.
- Try to make error messages sound uniform.
- Try to keep the code within 80 columns.
- Correct some typos.
- Correct some function declarations to match their prototypes.
- Remove unused headers, macros and variables.
- Remove a bzero() superfluous due to allocating with M_ZERO.
- Use FBSDID.
Remove a check about whether sa->sa_len is equal to salen from
getnameinfo(3). POSIX standard does not require a sa_len field
in sockaddr struct, hence such requirement will cause problem
for portability.

Disable negative name caching for msdosfs to work around a bug.
Since the name cache is case-sensitive and msdosfs isn't,
creating a file 'foo' won't invalidate a negative entry for 'FOO'.
There are similar problems related to 8.3 filenames.
A better solution is to override VOP_LOOKUP with a method that
canonicalizes the name, then calls vfs_cache_lookup(). Unfortunately,
it's not quite that simple because vfs_cache_lookup() will call
msdosfs_lookup() on a cache miss, and msdosfs_lookup() needs a way to
get at the original component name.
Concatenate the line number rather than the string `__FILE__' in the
NET_NEEDS_GIANT macro. Until now this wasn't a problem because no
translation unit contains NET_NEEDS_GIANT more than once.
Introduce three additional MAC Framework and MAC Policy entry points to
control socket poll() (select()), fstat(), and accept() operations,
required for some policies:
In mac_get_fd(), remove unconditional acquisition of Giant around copying
of the socket label to thread-local storage, and replace it with
conditional acquisition based on debug.mpsafenet. Acquire the socket
lock around the copy operation.
In mac_set_fd(), replace the unconditional acquisition of Giant with
the conditional acquisition of Giant based on debug.mpsafenet. The socket
lock is acquired in mac_socket_label_set() so doesn't have to be
acquired here.
Reduce the width of the THR column to 4 characters, to avoid wrap-around
of lines in SMP machines (which are wider), until we have a better way
of handling window sizes & columns in top.
