requests where uio_offset is not 0 to begin with. This fixes a long-
standing bug where e.g. 'cat /proc/$$/regs' would loop forever.

- Fix bug that prevented EEOR mode from working
and simplified the can_we_split code in the process.
- Reduce lock contention for the tcb_send_lock. I did
this especially for EEOR mode, still need to look at
why I need a lock when removing from the tailq and the
->next is NOT null. A lock fixes it but it implies a
bug yet exists.
- Activated Andre's proposed changes to better use the mbuf
infrastructure.
- Fixed places that were not using the aloc macro's to take
advantage of the per assoc cache.
- Adds ifdef fix so any logging will enable stat_logging to
get the right data structures in place (suggested by Max Laier).
use to synchornize and protect all data objects that are used for that
SIM. Drivers that are not yet MPSAFE register Giant and operate as
usual. RIght now, no drivers are MPSAFE, though a few will be changed
in the coming week as this work settles down.
The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to
be recompiled.
At some point in ZFS porting cycle I wasn't able to open snapshot datasets
in DS_MODE_PRIMARY mode and I changed it to DS_MODE_STANDARD. It seems
that it works just fine with DS_MODE_PRIMARY mode now, but I don't really
know what have changed.

* use "AR_GNU" as the format name instead of AR_SVR4 (it's what everyone is going to call it anyway)
* Simplify numeric parsing to unsigned (none of the numeric values should ever be negative); don't run off end of numeric fields.
* Finish parsing the common header fields before the next I/O request (which might dump the contents)
* Be smarter about format guessing and trimming filenames.
* Most of the magic values are only used in one place, so just inline them.
* Many more comments.
* Be smarter about handling damaged entries; return something reasonable.
* Call it a "filename table" instead of a "string table"
* Update tests.
Enable selection of 'ar', 'arbsd', and 'argnu' formats by name
(this allows bsdtar to create ar format archives).
The 'ar' writer still needs some work; it should reject
entries that aren't regular files and should probably also
strip leading paths from filenames.
implement robust version of m_collapse
add support for sf_buf
add fix for m_iovappend
add calls to m_sanity under INVARIANTS
fix m_freem_vec to correctly travese the mbuf iovec chain
The pfs_info mutex is only needed to lock pi_unrhdr. Everything else
in struct pfs_info is modified only while Giant is held (during
vfs_init() / vfs_uninit()); add assertions to that effect.
Simplify pfs_destroy somewhat.
Remove superfluous arguments from pfs_fileno_{alloc,free}(), and the
assertions which were added in the previous commit to ensure they were
consistent.
Assert that Giant is held while the vnode cache is initialized and
destroyed. Also assert that the cache is empty when it is destroyed.
Rename the vnode cache mutex for consistency.
Fix a long-standing bug in pfs_getattr(): it would uncritically return
the node's pn_fileno as st_ino. This would result in st_ino being 0
if the node had not previously been visited by readdir(), and also in
an incorrect st_ino for process directories and any files contained
therein. Correct this by abstracting the fileno manipulations
previously done in pfs_readdir() into a new function, pfs_fileno(),
which is used by both pfs_getattr() and pfs_readdir().
on int, but in fact it should operate on long.
- Introduce 'lvalue' variable, which is long.
- Fix _SC_XOPEN_SHM for 64bit archs.
- Fix _SC_PHYS_PAGES for 64bit archs.

- Use lvalue for pathconf(3), as it returns long.
- Cast value explicitly to long on return.
- Reduce default number of spa_zio_* threads to N*spa_zio_issue
plus N*spa_zio_intr threads per ZIO type, where N is the number
of CPUs.
- Put ZIO type number in thread's name.
sendmsg() while using a 0-length msg_controllen. This isn't allowed in
the FreeBSD system call ABI, so detect this case and set msg_control to
NULL. This allows Linux ping to work.

titles extracted from argv vector instead of the real executable names.
This is useful when you want to watch applications that set their status
information via setproctitle(3).

MFC after: 2 weeks
- name change of prefered -> preferred
- CMT fast recover code added.
- Comment fixes in CMT.
- We were not giving a reason of cant_start_asoc per socket api
if we failed to get init/or/cookie to bring up an assoc. Change
so we don't just give a generic "comm lost" but look at actual
states of dying assoc.
- change "crc32" arguments to "crc32c" to silence strict/noisy
compiler warnings when crc32() is also declared
- A few minor tweaks to get the portable stuff truely portable
for sctp6_usrreq.c :-D
- one-2-one style vrf match problem.
- window recovery would leave chks marked for retran
during window probes on the sent queue. This would then
cause an out-of-order problem and assure that the flight
size "problem" would occur.
- Solves a flight size logging issue that caused rwnd
overruns, flight size off as well as false retransmissions.g
- Macroize the up and down of flight size.
- Fix a ECNE bug in its counting.
- The strict_sacks options was causing aborts when window probing
was active, fix to make strict sacks a bit smarter about what
the next unsent TSN is.
- Fixes a one-2-one wakeup bug found by Martin Kulas.
- If-defed out form, Andre's copy routines pending his
commit of at least m_last().. need to adjust for 6.2 as
well.. since m_last won't exist.
