1c7c3c6a86 This is a rather large commit that encompasses the new swapper, 
changes to the VM system to support the new swapper, VM bug
    fixes, several VM optimizations, and some additional revamping of the
    VM code.  The specific bug fixes will be documented with additional
    forced commits.  This commit is somewhat rough in regards to code
    cleanup issues.

15a1057c46 Add 'options DEBUG_LOCKS', which stores extra information in struct 
lock, and add some macros and function parameters to make sure that
the information get to the point where it can be put in the lock
structure.

While I'm here, add DEBUG_VFS_LOCKS to LINT.

1351d07f0d Mountroot could concievably make sense to a KLD though, in the preload 
case.  I'm not sure the autoconf code is up to it though...

de5d1ba57c Don't pass unused unused timestamp args to UFS_UPDATE() or waste 
time initializing them.  This almost finishes centralizing (in-core)
timestamp updates in ufs_itimes().

75ba77578f A partial implementation of the procfs cmdline pseudo-file. This 
is enough to satisfy things like StarOffice.  This is a hack, but doing
it properly would be a LOT of work, and would require extensive grovelling
around in the user address space to find the argv[].

9d9fdb45c5 Ensure that deHighClust in direntry always initialized. 
Noticed by: 	Carl Mascott <cmascott@world.std.com>

Don't write access time of a file more than once per day. (Its precision is
1 day anyway). Don't try to write access and creation time in nonwin95 case.

f2aed91b48 Made this compile if UMAPFS_DIAGNOSTIC is defined. This has been broken 
since before rev.1.1, so UMAPFS_DIAGNOSTIC should not be trusted.
UMAPFS_DIAGNOSTIC is commented out in LINT to hide various bugs.

2127f26023 Examine all occurrences of sprintf(), strcat(), and str[n]cpy() 
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

6f72efa21b Change the way unmounting happens to guarantee that the 
client programs are allowed to finish up (coda_call is
forced to complete) and release their locks.  Thus there
is a reasonable chance that the vflush implicit in the
unmount will not get hung on held locks.

65baf8f06b Don't follow null bdevsw pointers. The `major(dev) < nblkdev' test rotted 
when bdevsw[] became sparse.  We still depend on magic to avoid having to

8994ca3ce9 Removed statically configured mount type numbers (MOUNT_*) and all 
references to them.

The change a couple of days ago to ignore these numbers in statically
configured vfsconf structs was slightly premature because the cd9660,
cfs, devfs, ext2fs, nfs vfs's still used MOUNT_* instead of the number
in their vfsconf struct.
