o Rename some functions for clarity:
- sctp_add/del_local_addr_assoc to xxx_local_addr_restricted()
- asconf related iterator functions to sctp_asconf_iterator_xxx()
o Fix bug when the same address is deleted and added (and removed from
the asconf queue) where the ifa is "freed" twice refcount wise,
possibly freeing it completely.
o Fix bug in output where the first ASCONF would not go out after the
last address is changed (e.g. only goes out when retransmitted).
o Fix bug where multiple ASCONFs can be bundled in the same packet with
the and with the same serial numbers.
o Fix asconf stcb iterator to not send ASCONF until after all work
queue entries have been processed.
o Change behavior so that when the last address is deleted (auto asconf
on a bound all endpoint) no action is taken until an address is
added; at that time, an ASCONF add+delete is sent (if the assoc
is still up).
o Fix local address counting so that address scoping is taken into
account.
o #ifdef SCTP_TIMER_BASED_ASCONF the old timer triggered sending
of ASCONF (after an RTO). The default now is to send
ASCONF immediately (except for the case of changing/deleting the
last usable address).

Because nfe(4) hardware doesn't support SG on Rx path, supporting
jumbo frame requires very large contiguous kernel memory(i.e. several
mega bytes). In case of lack of contiguous kernel memory that
allocation request may always fail. However nfe(4) can operate on normal
sized MTU frames, so go ahead and just disable jumbo frame support.
While I'm here add a new tunable "hw.nfe.jumbo_disable" to disable
jumbo frame support.
In nfe_poll, make sure to invoke correct Rx handler.

o Initialize ownerships and permissions. They were garbage (0) for
root mounts since vfs_mountroot_try() doesn't ask for them to be set
and msdosfs's old incomplete code to set them was removed. The
garbage happened to give the correct ownerships root:wheel, but it
gave permissions 000 so init could not be execed. Use the macros
for root: wheel and 0755. (The removed code gave 0:0 and 0777. 0755
is more normal and secure, thought wrong for /tmp.)
o Check the readonly flag for initial (non-MNT_UPDATE) mounts in the
correct place, as in ffs. For root mounts, it is only passed in
mp->mnt_flags, since vfs_mountroot_try() only passes it as a flag
and nothing translates the flag to the "ro" option string. msdosfs
only looked for it in the string, so it gave a rw mount for root
mounts without even clearing the flag in mp->mnt_flags, so the final
state was inconsistent. Checking the flag only in mp->mnt_flags
works for initial userland mounts too. The MNT_UPDATE case is
messier.
The main point that should work but doesn't is fsck of msdosfs root
while it is mounted ro. This needs mainly MNT_RELOAD support to work.
It should be possible to run fsck -p and succeed provided the fs is
consistent, not just for msdosfs, but this fails because fsck -p always
tries to open the device rw. The hack that allows open for writing
in ffs is not implemented in msdosfs, since without MNT_RELOAD support
writing could only be harmful. So fsck must be turned off to use
msdosfs as root. This is quite dangerous, since msdosfs is still missing
actually using its fs-dirty flag internally, so it is happy to mount
dirty fileystems rw.
Unrelated changes:
- Fix missing error handling for MNT_UPDATE from rw to ro.
- Catch up with renaming msdos to msdosfs in a string.

or replace (i.e., zdump) the environment after a call to setenv(), putenv()
or unsetenv() has been made, a few changes were made.
- getenv() will return the value from the new environ array.
- setenv() was split into two functions: __setenv() which is most of the
previous setenv() without checks on the name and setenv() which
contains the checks before calling __setenv().
- setenv(), putenv() and unsetenv() will unset all previous values and
call __setenv() on all entries in the new environ array which in turn
adds them to the end of the envVars array. Calling __setenv() instead
of setenv() is done to avoid the temporary replacement of the '=' in a
string with a NUL byte. Some strings may be read-only data.
Added more regression checks for clearing the environment array.
Replaced gettimeofday() with getrusage() in timing regression check for
better accuracy.
Fixed an off-by-one bug in __remove_putenv() in the use of memmove(). This
went unnoticed due to the allocation of double the number of environ
entries when building envVars.
Fixed a few spelling mistakes in the comments.

4KB pages as i386, data structures that just fit in one page on i386 (and
on 64 bit architectures with 8KB pages) can be distributed over two pages
on amd64. This is a porblem in the case of the Symbios driver, since the
SCRIPTS engine in the SCSI chip operates on physical addresses and needs
physically contiguous memory. Earlier patches used contigmalloc on amd64,
but this version replaces part of a structure by a pointer to that data.
In order to not introduce an extra indirection for other architectures,
the change has been made conditional on __amd64__.
Earlier attempts to repair this problem are removed (i.e. the macros that
made amd64 use contigmalloc). The fix was submitted by Jan Mikkelsen and
modified by me to only affect amd64.

This gives a very large speedup for small block sizes (in my tests,
about 5 times for write and 3 times for read with a block size of 512,
if clustering is possible) and a moderate speedup for the moderatatly
large block sizes that should be used on non-small media (4K is the
best size in most cases, and the speedup for that is about 1.3 times
for write and 1.2 times for read). mmap() should benefit from clustering
like read()/write(), but the current implementation of vm only supports
clustering (at least for getpages) if the fs block size is >= PAGE SIZE.
msdosfs is now only slightly slower than ffs with soft updates for
writing and slightly faster for reading when both use their best block
sizes. Writing is slower for msdosfs because of more sync writes.
Reading is faster for msdosfs because indirect blocks interfere with
clustering in ffs.
The changes in msdosfs_read() and msdosfs_write() are simpler merges
of corresponding code in ffs (after fixing some style bugs in ffs).
msdosfs_bmap() needs fs-specific code. This implementation loops
calling a lower level bmap function to do the hard parts. This is a
bit inefficient, but is efficient enough since msdsfs_bmap() is only
called when there is physical i/o to do.

In msdosfs_read(), mainly reorder the main loop to the same order as in
ffs_read().
In msdosfs_write() and extendfile(), use vfs_bio_clrbuf() instead of
clrbuf(). I think this just just a bogus optimization, but ffs always
does it and msdosfs already did it in one place, and it is what I've
tested.
In msdosfs_write(), merge good bits from a comment in ffs_write(), and
fix 1 style bug.
In the main comment for msdosfs_pcbmap(), improve wording and catch
up with 13 years of changes in the function. This comment belongs in
VOP_BMAP.9 but that doesn't exist.
In msdosfs_bmap(), return EFBIG if the requested cluster number is out
of bounds instead of blindly truncating it, and fix many style bugs.

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.
