When nbytes=0, sendfile(2) should use file size. Because of the bug, it
was sending half of a file. The bug is that 'off' variable can't be used
for size calculation, because it changes inside the loop, so we should
use uap->offset instead.
contigmalloc2() was always testing the first physical page for PG_ZERO,
not the current page of interest.

gets a bogus irq storm detected when periodic daily kicks off at 3 am
and disconnects the disk. Change the print logic to print once per second
when the storm is occurring instead of only once. Otherwise, it appeared
that something else was causing the errors each night at 3 am since the
print only occurred the first time.

The support for RFC 2640 (UTF8) is optional and rudimentary.
The server just advertises its capability to handle UTF-8 file
names and relies on its own 8-bit cleanness, as well as on
the backward compatibility of UTF-8 with ASCII. So uploaded
files will have UTF-8 names, but the initial server contents
should be prepared in UTF-8 by hand, no on-the-fly conversion
of file names will be done.

on a snapshot directory:
- Remove PRIV_VFS_MOUNT check - regular users can mount snapshots
via lookups on snapshot directory.
- Reset mount credential to kcred, so user won't be able to unmount
the snapshot.
- Reset owner uid.
- Unlock vnode in case of a failure.

Previously whenever PROMISC mode turned on/off link renegotiation
occurs and it could resulted in network unavailability for serveral
seconds.(Depending on switch STP settings it could last several tens
seconds.)

entry limit may be smaller than the bucket rows and their limit
combined however. Thus only try to free a syncache entry if we
found one in this bucket row.

to move up the start address until the allocation succeeds. If the
alignment of the resource was 0, then the code would keep trying the same
request in an infinite loop and hang. Force the request to always move
start up by at least 1 byte each time through the loop.
The 6105M and 6102 does not have the DWORD alignment problem, so
don't m_defrag() every packet in the transmit path for those.
More stringent usage of tx-descriptor ring and its flags.
Tested on 6102 and 6105M, other chips may also be able to run
without the m_defrag() but I have neither hardware nor docs to
find out.
