particule device. In doing this, make a new the bpf_stat structure with
members that are u_long rather than u_int, matching the counters in the bpf_d.
the original bpf_stat is now bpf_stat_old and so to the original ioctl
is preserved as BIOCGSTATSOLD.
this fixes PR#25014. i386 GENERIC can re-enable PERFCTRS by default now
(it was disabled with x86 SMP support was commited to the trunk.)
XXX: should add P4 support
XXX: should add MP support
this addresses pr/23924
this includes most of support for creating fslevel 3 compatible filesystems,
although there is currently no command line option to invoke it when
not using apple_ufs
not a read operation should be allowed to sleep. This allows the use of
bd_rtout with a value of "-1" to be eliminated (signed comparison and
assignment to an unsigned long.)
* in 1.91, a change was introduced that had bpfpoll() returning POLLRDNORM
set when the timeout expired. This impacted poorly on performance as well
as causing select to return an fd available for reading when it wasn't.
Change the behaviour here to only allow the possibility of POLLIN being
returned as active in the event of a timeout.
the PCIX bus start to get heavily loaded. This only happen when using
chained descriptors, therefore work-around it by providing a private
pool of receive buffers able to contain a full-sized packet.
in tsleep()/wakeup() to appease gcc. Otherwise, the ch_flags value may
be cached in a register in atabus_thread(), and when it sets the WDCF_TH_RUN
bit after tsleep() it may loose loose the changes made by an interrupt handler
or another thread.

This makes it possible to use expressions like
${("${LIST:Msomething"}):?present:absent}
it also makes treatment of lhs and rhs more consistent, and
makes CondToken easier to read.
Update unit-test/cond1 to test new features.
(cd ${.CURDIR}/somedir && ${MAKE} AVAR=value atarget)
to
${MAKEDIRTARGET} somedir atarget AVAR=value
which results in a "prettier" display of these operations
