Xenstore user-space device has two problems currently:
- It does not correctly handle concurrent clients, because it's storing
each client data in dev->si_drv1.
- It does not correctly free this data when the client closes the device.
In order to solve both of this issues store the per-client data using
cdevpriv, which also comes with a hook in order to perform the necessary
cleanup on device close.
While there also make the device eternal.

It makes sfxge_tso_state smaller and even makes tso_start_new_packet()
few bytes smaller. Data used to calculate packet size are used nearby,
so it should be no problems with cache etc.

That partially fixes IPv6 fragment handling. Thanks to Kristof for

* Do not subvert vfs.timestamp_precision by reading the time and passing
that to utimensat(). Instead, pass UTIME_NOW. A fallback to a NULL times
pointer is no longer used.
* Do not ignore -a/-m if the user has write access but does not own the
file. Leave timestamps unchanged using UTIME_OMIT and do not fall back to
a NULL times pointer (which would set both timestamps) if that fails.

I don't like having it in this function; I may migrate it to ar9300_freebsd.c
at some point to keep the HAL code pollution down.
This allows ANI to be disabled via a sysctl.
Tested:
* AR9331, STA/TDMA modes
timeout previously collected only one child status with wait(2). If this
was one of the grandchildren timeout would return to sigsuspend and wait
until the timeout expired. Instead, loop for all children.

This is a custom FreeBSD HAL method that is used by the TDMA code
to program the beacon timers directly without any guesswork/assumptions
by the HAL.
This brings up basic TDMA master/slave support on the AR9380 HAL,
however there are other issues preventing it from being stable.
(I'm seeing beacon interval instability, which may be due to
busy 2GHz air, but also may be due to some HAL configuration
issues with regards to ANI, or hardware timer programming, etc.)
Tested:
* AR9331 (Carambola2), STA, AP, adhoc and TDMA master mode.
As a followup to r278363, there is one more case where
stayopen can be accessed uninitialized, but even after
swapping arguments, access is possible in some other
cases so prevent it completely by initializing stayopen.

The existing implementation had a broken comparison that could
overflow and return confusing values. Replace this with a check
that avoids the overflow before it happens.
Consistently return a maximum value also on the case of negative
arguments since negative is considered an overflow and means
infinity for our current setrlimit().
New revamped version is credited to Bruce Evans.

The e2fs_gd struct was not being initialized and garbage was
being used for hinting the ext2 allocator variant.
Use malloc to clear the values and also initialize e2fs_contigdirs
during allocation to keep consistency.

This probably supports other devices based on SeaBIOS, which need
to be added to the smbios based quirks table.
The functionality has been ported from DragonFlyBSD and adapted
to FreeBSD's more general purpose environment.
Devices not covered by a quirk shouldn't be affected at all. Thanks
to jhb and kostikbel for reviewing the code.

It is safe to move the call to socantsendmore_locked() after
sbdrop_locked() as long as we hold the sockbuf lock across the two
calls.
