coda.h:
- CodaFid typdef -> struct CodaFid throughout.
- Use unsigned int instead of unsigned long for venus_dirent and other
cosmetic fixes.
- Introduce cuid_t and cgid_t and use instead of uid_t and gid_t in RPCs.
- Synchronize comments and macros.
- Use u_int32_t instead of unsigned long for coda_out_hdr.
With these changes, a 64-bit Coda kernel module now works with
coda6_client, whereas previous userspace and kernel versions of RPCs
differed sufficiently to prevent using the file system. This has been
verified only with casual testing, but /coda is now usable for at least
basic operations on amd64.

the VFS. Now all the VFS_* functions and relating parts don't want the
context as long as it always refers to curthread.
In some points, in particular when dealing with VOPs and functions living
in the same namespace (eg. vflush) which still need to be converted,
pass curthread explicitly in order to retain the old behaviour.
Such loose ends will be fixed ASAP.
While here fix a bug: now, UFS_EXTATTR can be compiled alone without the
UFS_EXTATTR_AUTOSTART option.
VFS KPI is heavilly changed by this commit so thirdy parts modules needs
to be recompiled. Bump __FreeBSD_version in order to signal such
situation.

- Rename print_vattr to coda_print_vattr and make static, rename
print_cred to coda_print_cred.
- Remove unused coda_vop_nop.
- Add XXX comment because coda_readdir forwards to the cache vnode's
readdir rather than venus_readdir, and annotate venus_readdir as
unused.
- Rename vc_nb_* to vc_*.
- Use d_open_t, d_close_t, d_read_t, d_write_t, d_ioctl_t and d_poll_t
for prototyping vc_* as that is the intent, don't use our own
definitions.
- Rename coda_nb_statfs to coda_statfs, rename NB_SFS_SIZ to
CODA_SFS_SIZ.
- Replace one more OBE reference to NetBSD with a reference to FreeBSD.
- Tidy up a little vertical whitespace here and there.
- Annotate coda_nc_zapvnode as unused.
- Remove unused vcodattach.
- Annotate VM_INTR as unused.
- Annotate that coda_fhtovp is unused and doesn't match the FreeBSD
prototype, so isn't hooked up to vfs_fhtovp. If we want NFS export of
Coda to work someday, this needs to be fixed.
- Remove unused getNewVnode.
- Remove unused coda_vget, coda_init, coda_quotactl prototypes.

No need to clear the VV_ROOT flag on mi_rootvp flag (especially after

Remove this argument and pass curthread directly to underlying
VOP_LOCK1() VFS method. This modify makes the code cleaner and in
particular remove an annoying dependence helping next lockmgr() cleanup.
KPI results, obviously, changed.
Manpage and FreeBSD_version will be updated through further commits.
As a side note, would be valuable to say that next commits will address
a similar cleanup about VFS methods, in particular vop_lock1 and
vop_unlock.

We allocate coda_ctlvp when /coda is mounted, but never release it.
During the unmount this vnode was marked as UNMOUNTING and when venus
is started a second time the system would hang, possibly waiting for
the old vnode to disappear.
So now we call vrele on the control vnode when file system is unmounted
to drop the reference we got during the mount. I'm pretty sure it is
also necessary to not skip the handling in coda_inactive for the control
vnode, it seems like that is the place we actually get rid of the vnode
once the refcount has dropped to 0.

- Prefer '_' to ' ', as it results in more easily parsed results in
memory monitoring tools such as vmstat.
- Remove punctuation that is incompatible with using memory type names
as file names, such as '/' characters.
- Disambiguate some collisions by adding subsystem prefixes to some
memory types.
- Generally prefer lower case to upper case.
- If the same type is defined in multiple architecture directories,
attempt to use the same name in additional cases.
Not all instances were caught in this change, so more work is required to
finish this conversion. Similar changes are required for UMA zone names.

I'm not sure why a credential was added to these in the first place, it is
not used anywhere and it doesn't make much sense:
The credentials for syncing a file (ability to write to the
file) should be checked at the system call level.
Credentials for syncing one or more filesystems ("none")
should be checked at the system call level as well.
If the filesystem implementation needs a particular credential
to carry out the syncing it would logically have to the
cached mount credential, or a credential cached along with
any delayed write data.

remaining consumers to have the count passed as an option. This is
i4b, pc98/wdc, and coda.
Bump configvers.h from 500013 to 600000.
Remove heuristics that tried to parse "device ed5" as 5 units of the ed
device. This broke things like the snd_emu10k1 device, which required
quotes to make it parse right. The no-longer-needed quotes have been
removed from NOTES, GENERIC etc. eg, I've removed the quotes from:
device snd_maestro
device "snd_maestro3"
device snd_mss
I believe everything will still compile and work after this.

Name our filesystems mount function consistently.
Eliminate the namiedata argument to both vfs_mount and vfs_omount.
It was originally there to save stack space. A few places abused
it to get hold of some credentials to pass around. Effectively
it is unused.

Add a new CODA_COMPAT_5 option, which requests support for the old
Coda 5.x interface instead of the new one.
Create a new coda5.ko module that supports the 5.x interface, and make
the existing coda.ko module use the new 6.x interface. These modules
cannot both be loaded at the same time.

- v_vflag is protected by the vnode lock and is used when synchronization
with VOP calls is needed.
- v_iflag is protected by interlock and is used for dealing with vnode
management issues. These flags include X/O LOCK, FREE, DOOMED, etc.
- All accesses to v_iflag and v_vflag have either been locked or marked with
mp_fixme's.
- Many ASSERT_VOP_LOCKED calls have been added where the locking was not
clear.
- Many functions in vfs_subr.c were restructured to provide for stronger
locking.

This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.
