devsd: fix possible sdbio() race with inquiry data changing (due to ahci hotplug)
the unit inquiry data might change in case the drive got pulled
with ahci. so keep track if we locked the ctl in a local stack
variable instead of relying on that the inquiry data stays the
same.

bio: remove useless Breadn() as it does the same as Bread()
Bread() always reads exactly nbytes of data if it can. only
when it reaches end of file or an error it will return less.
so the Breadn() function that was introduced has been removed.

sdiahci: prevent x301 dvd-ram from hanging machine
matushita dvd-ram on thinkpad x301 hangs on the inquiry command
done from scsiverify(). not sure whats wrong with it, but at least
this makes the machine boot.
wait for the drives to become ready or missing in iaonline()
and iaverify() to prevent nobootprompt= race.
handle task file error status (this can happen for atapi)
under some circumstances and would hang the io if not
handled.
preventively poll interrupts from the checkdrive kproc in
case we loose interrupts (bad via machine).
implement bios handoff procedure.
make sure the port is idle before programming the port dma
regios in configdrive(), do not start command processing
on the port unless phylink has been established.

readprocfdinit()
fix buffer overflow in execlp(), check if name
of failed exec starts with / . or is \0
make sure not to close our own filedescriptors
for FD_CLOEXEC in execve(), fix wrong length

fix error handling cases. copy the enviroment

environ[] array might not be writable.
remove bogus close if we fail to open ppid file
in getppid() and use /dev/ppid instead of #c/ppid
setting Asud in the cmd register is not needed, because
Apwr is (Asud|Apod) already. the problem really was that
the drive comes up with sstatus Spresent (001), so we never
spun it up because (p->sstatus & Sphylink) == 0 was never
met (Sphylink being a mask (011) overlaping Spresent bit).
the spinup wait loop has to run only for the staggered spinup
case (h->cap & Hss) and it should wait for the drive to be
detected by the phy, not just cold presence detect.
