8c18819a81 Don't wake up the thread after the signal handler
has been executed. On return from the signal handler
the call will either be restarted or EINTR will be returned,
but it will not go back to its previous state. So, it is
sufficient to simply change the state to 'running' without
actually trying to wake up the thread.

bddcdc5193 Use size_t or ssize_t wherever appropriate instead of casting from int *
to size_t *, which is incorrect because they may have different widths.
This caused some subtle forms of corruption, the mostly frequently
reported one being that the last character of a filename was sometimes
duplicated on amd64.

77fa00fa7c Switch to using the new $PIR interrupt routing code and remove the old
code.  The pci_cfgreg.c file now just controls reading/writing PCI config
registers.

2e41ba54d6 Rework the $PIR (aka PCIBIOS) PCI interrupt routing code and split it off
into its own file:
- All of the $PIR interrupt routing is now done in a link-centric fashion.
  When a host-PCI bridge that uses the $PIR attaches, it calls pir_parse()
  to parse the table.  This scans for link devices and merges all the masks
  for each link device from the table entries.  It then looks at the intline
  register of PCI devices connected to a link to figure out if the BIOS has
  routed this link and if so to which IRQ.
- The IRQ for any given link can be overridden via a hint like so:
  'hw.pci.link.0x62.irq=10'  Any IRQ set in this matter is treated as if it
  were set that way by the BIOS.
- We only call the BIOS to route each link device once.
- When a PCI device wants to route an interrupt, we look it up in the $PIR
  to find the associated link.  If the link is routed, we simply return the
  IRQ it is using.  If it is not routed, we have to pick one.  This uses a
  different algorithm from the old code.  First off, when we try to pick
  an interrupt from a mask of possible interrupts, we try to pick the one
  that is least loaded as far as PCI devices.  We maintain this weight based
  on the number of devices attached to each link device.  When choosing an
  IRQ, we first attempt to route using any PCI only interrupts (the old
  code did this as well).  If that doesn't work, we try to use the list of
  IRQs that the BIOS has used.  This is a new step that the new code didn't
  do and avoids using IRQ 3 or 4 for every virgin interrupt routing.  If
  none of the IRQs that the BIOS used worked, then we fall back to trying
  anything.
- The fallback mask for !PC98 was fixed to include IRQ 3 and not allow IRQ
  2.
- We don't use the $PIR to route interrupts on a PCI-PCI bridge unless it
  has already been used to route on at least one Host-PCI bridge.  This
  helps to avoid mixing and matching x86 firmware PCI interrupt routing
  methods (which is a Bad Thing(tm)).

0b7ed341e1 Change the disk(9) API in order to make device removal more robust.
Previously the "struct disk" were owned by the device driver and this
gave us problems when the device disappared and the users of that device
were not immediately disappearing.

Now the struct disk is allocate with a new call, disk_alloc() and owned
by geom_disk and just abandonned by the device driver when disk_create()
is called.

Unfortunately, this results in a ton of "s/\./->/" changes to device
drivers.

Since I'm doing the sweep anyway, a couple of other API improvements
have been carried out at the same time:

The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to
DISKFLAG_NEEDSGIANT

A version number have been added to disk_create() so that we can detect,
report and ignore binary drivers with old ABI in the future.

Manual page update to follow shortly.

32eaa7dddd There are consumers of rwlocks, inluding our own libc, that depend on
a PTHREAD_RWLOCK_INITIALIZER to do for rwlocks what
a similarly named symbol does for statically initialized mutexes.
This symbol was dropped in The Open Group Base Specifications Issue 6
and does not exist in IEEE Std 1003.1, 2003, but it should still be
supported for backwards compatibility.
