- Add _Alignas(). Unfortunately this macro is only partially functional.
The C1X standard will allow both an integer and a type name to be
passed to this macro, while this macro only allows an integer. To be
portable, one must use _Alignas(_Alignof(double)) to use type names.
- Don't do _Static_assert() when __COUNTER__ is not supported. We'd
better keep this implementation robust and allow it to be used in
header files, without mysteriously breaking older compilers.

- _Alignof(), which returns the aligment of a certain type.
- _Static_assert(), which can be used to check compile-time assertions.

o Add check for actually resolved speed in miibus_statchg callback
instead of blindly reprogramming BCE_EMAC_MODE register. The
callback may be called multiple times(e.g. link UP, link
transition, auto-negotiate complete etc) while auto-negotiation
is in progress. All unresolved link state changes are ignored
now and setting BCE_EMAC_MODE after link establishment is done
once.
o bce(4) is careful enough not to drive MII_TICK if driver got a
valid link. To detect lost link, bce(4) relied on link state
change interrupt and if driver see the interrupt, it forced to
drive MII_TICK by calling bce_tick() in interrupt handler.
Because bce(4) generates multiple link state change interrupts
while auto-negotiation is in progress, bce_tick() would be
called multiple times and this resulted in generating multiple
link UP/DOWN messages.
With this change, bce_tick() is not called in interrupt handler
anymore such that miibus_statchg callback handles link state
changes with consistent manner.

__COUNTER__ allows one to obtain incrementing (read: unique) numbers
from the C preprocesor. This is useful when implementing things like a
robust implementation of CTASSERT(), which currently fails when using
it more than once on a single line of code. Probably not likely to cause
any breakage, but still.
__COUNTER__ was also added to GCC 4.3, but since that implementation is
GPLv3 licensed, I took the liberty of implementing it without looking at
any upstream sources. Therefore, this version is licensed under the same
license as the rest of the code; GPLv2.
If I interpret the C standard correctly, the storage specifier should be
placed before the inline keyword. While at it, replace __inline by
inline in the files affected.
As C1X is close to being released, there is no need to wrap around a
feature that is already part of C90. Most of these files already use
`const' in different placed as well.
that changed 0.0.0.0/0.0.0.0 prefix to 0.0.0.0/255.0.0.0.
In the r228313 this behavior was fixed, and since dhclient-script
got broken.
I'm not sure this fix is a perfect one, it just changes
dhclient-script to set 0.0.0.0/255.0.0.0 explicitly.

- in destroy_lun_state() assert hold == 1 instead of 0, as it should
receive hold taken by the create_lun_state() or get_lun_statep() before;
- fix hold count leak inside rls_lun_statep() that also fired above assert;
- in destroy_lun_state() use SIM bus number instead of SIM path id for
ISP_GET_PC_ADDR(), as it was before r196008;
- make isp_disable_lun() to set status in CCB;
- make isp_target_mark_aborted() set status into the proper CCB.

This tool only consists of a single C file, so we can simply mark
everything except main() static. This seems to shave off about 8% of the

lock_success/lock_failure, introduced in r228424, by directly skipping

This mainly helps in avoiding namespace pollution and thus lockstat.h
dependency by systm.h.
As an added bonus, this also helps in MFC case.

typedef bool. Due to macro expansion it seemed better to use a
typedef for kernel consumers (specifically ofed won't compile
without more changes if a define is used).
- <stdbool.h> should also not re-define bool/true/false if they are
defined by <sys/types.h>. It would probably be a programming error
to define _KERNEL for user-space code, but downstream consumers
like Isilon have already been including <stdbool.h> in kernel
sources, and this protects that usage.
- sizeof(_Bool) is not necessarily the same as sizeof(int), so kernel
modules should be rebuild with this change. Bump __FreeBSD_version.
