1587b568dd Fix panic for `cp -p' by root to an msdos file system. Improve handling
of attributes so that `cp -p' to an msdos file system can succeed under
favourable circumstances (no uid or gid changes and no nonzero flags
except SF_ARCHIVED).

msdosfs_vnops.c:
The in-core inode flags were confused with the on-disk inode flags, so
chflags() clobbered the lock flag and caused a panic.

denode.h, msdosfs_denode.c, msdosfs_vnops.c:
Support the msdosfs archive attibute (ATTR_ARCHIVE) by mapping it to
the complement of the SF_ARCHIVED flag and setting the ATTR_ARCHIVE
bit when a file's modification time is set (but not when a file's
permissions are set; this is the standard wrong DOS behaviour).

denode.h, msdosfs_denode.c:
Remove the DE_UPDAT() macro.  It was only used once, and the corresponding
macro in ufs has already been removed.

denode.h:
Don't change the timestamp for directories in DE_TIMES() (be consistent
with deupdat()).

msdosfs_vnops.c:
Handle chown() better: return EPERM instead of EINVAL if there are
insufficient permissions; otherwise, allow null changes.

e62de5875e Fix numerous timestamp bugs.
DE_UPDATE was confused with DE_MODIFIED in some places (they do have
confusing names).  Handle them exactly the same as IN_UPDATE and
IN_MODIFIED.  This fixes chmod() and chown() clobbering the mtime
and other bugs.

DE_MODIFIED was set but not used.

Parenthesize macro args.

DE_TIMES() now takes a timeval arg instead of a timespec arg.  It was
stupid to use a macro for speed and do unused conversions to prepare
for the macro.

Restore the left shifting of the DOS seconds count by 1.  It got
lost among the shifts for the bitfields, so DOS seconds counts
appeared to range from 0 to 29 seconds (step 1) instead of 0 to 58
seconds (step 2).

Actually use the passed-in mtime in deupdat() as documented so that
utimes() works.

Change `extern __inline's to `static inline's so that msdosfs_fat.o
can be linked when it is compiled without -O.

Remove faking of directory mtimes to always be the current time.  It's
more surprising for directory mtimes to change when you read the
directories than for them not to change when you write the directories.
This should be controlled by a mount-time option if at all.

e5d78dd23f From tim@cs.city.ac.uk (Tim Wilkinson):
Find enclosed a short bugfix to get the union filesystem up and running
in FreeBSD-current.  We don't think we've got all the problems yet but
these fixes sort out the major ones (which mostly concert bad locking
of vnodes), no doubt we'll post others as necessary.  Known problems
include the inability of the umount command (not the system call) to unmount
unions in certain circumstances (this is due the way "realpath" works),
and the failure of direntries to always get all available files in
unioned subdirectories.  We are, as they say, working on it.

1ea7c62e83 Fix from John Hay to avoid kernel panics when ap->a_eofflag is NULL.
I'm not sure if this is just masking another problem (like, should
ap->a_eofflag EVER be NULL?), but if it prevents a panic for now then
it may save an ALPHA customer.

c97639b923 1) cleaned up after Garrett - fixed more redundant declarations, changed
use of timeout_t -> timeout_func_t in aha1542 and aha1742 drivers.
2) fix a bug in the portalfs that was uncovered by better prototyping -
   specifically, the time must be converted from timeval to timespec
   before storing in va_atime.
3) fixed/added some miscellaneous prototypes

f9fc827448 Fix up some sloppy coding practices:
- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
  header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.

NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.
