Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI command register. The lazy BAR allocation code in FreeBSD sometimes disables this bit when it detects a range conflict, and will re-enable it on demand when a driver allocates the BAR. Thus, the bit is no longer a reliable indication of capability, and should not be checked. This results in the elimination of a lot of code from drivers, and also gives the opportunity to simplify a lot of drivers to use a helper API to set the busmaster enable bit.
This changes fixes some recent reports of disk controllers and their associated drives/enclosures disappearing during boot.

Make the newbus subsystem Giant free by adding the new newbus sxlock. The newbus lock is responsible for protecting newbus internIal structures, device states and devclass flags. It is necessary to hold it when all such datas are accessed. For the other operations, softc locking should ensure enough protection to avoid races.
Newbus lock is automatically held when virtual operations on the device and bus are invoked when loading the driver or when the suspend/resume take place. For other 'spourious' operations trying to access/modify the newbus topology, newbus lock needs to be automatically acquired and dropped.
For the moment Giant is also acquired in some key point (modules subsystem) in order to avoid problems before the 8.0 release as module handlers could make assumptions about it. This Giant locking should go just after the release happens.
Please keep in mind that the public interface can be expanded in order to provide more support, if there are really necessities at some point and also some bugs could arise as long as the patch needs a bit of further testing.
Bump __FreeBSD_version in order to reflect the newbus lock introduction.

Add crashdump support to the ips driver. It only works for the more modern ServeRAID 4 - 7 models right now. Support for older cards is possible, but I don't have any hardware to experiment with.
Thanks to Jack Hammer at Adaptec for providing debugging hints.

Lock the IPS driver and bring it out from under Giant. Also do some significant clean up and optimizations: - don't call bioq_disksort() on every command, the hardware will do that for us. - remove all of the complicated bio deferral code. bio's that can't be serviced immediately can just wait on the bioq. - Only reserve one command object for doing control commands to the card. This simplifies a lot of code and significantly reduces the size of the command struct. - Allocate commands out of a slab instead of embedding them into the softc. - Call the command action method directly instead of having ips_get_free_cmd() call it indirectly.

- Use the new resource_disabled() helper function to see if devices are disabled. - Change the apm driver to match the acpi driver's behavior by checking to see if the device is disabled in the identify routine instead of in the probe routine. This way if the device is disabled it is never created.
Note that a few places (ips(4), Alpha SMP) used "disable" instead of "disabled" for their hint names, and these hints must be changed to "disabled". If this is a big problem, resource_disabled() can always be changed to honor both names.

Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg. Lockfunc allows a driver to provide a function for managing its locking semantics while using busdma. At the moment, this is used for the asynchronous busdma_swi and callback mechanism. Two lockfunc implementations are provided: busdma_lock_mutex() performs standard mutex operations on the mutex that is specified from lockfuncarg. dftl_lock() is a panic implementation and is defaulted to when NULL, NULL are passed to bus_dma_tag_create(). The only time that NULL, NULL should ever be used is when the driver ensures that bus_dmamap_load() will not be deferred. Drivers that do not provide their own locking can pass busdma_lock_mutex,&Giant args in order to preserve the former behaviour.
sparc64 and powerpc do not provide real busdma_swi functions, so this is largely a noop on those platforms. The busdma_swi on is64 is not properly locked yet, so warnings will be emitted on this platform when busdma callback deferrals happen.
If anyone gets panics or warnings from dflt_lock() being called, please let me know right away.

- Zero the buffers used to hold configuration data from the card. Not doing so can leave stale data in the buffer and confuse the driver. - enable the ability to set the 'disable' hint for the driver to keep it from attaching. i.e. 'hw.ips.0.disable=1' will prevent the driver from attaching. - Only detach if attach suceeded.
