drm/i915: Restore pci_enable_busmaster() call in the init path

This fixes a GPU hang on i945GM.

While here, merge some minor fixes to DRM core and i915:
* Remove obsolete drm_agp_*_memory() prototypes
* Fix comment in drm_fops.c (outisde -> outside)
* Fix some formatting issues in drm_stub.c (spaces -> tabs)

drm: Update the device-independent code to match Linux 3.8.13

This update brings few features:
o Support for the setmaster/dropmaster ioctls. For instance, they
are used to run multiple X servers simultaneously.
o Support for minor devices. The only user-visible change is a new
entry in /dev/dri but it is useless at the moment. This is a
first step to support render nodes [1].

The main benefit is to greatly reduce the diff with Linux (at the
expense of an unreadable commit diff). Hopefully, next upgrades will be
easier.

No updates were made to the drivers, beside adapting them to API
changes.

Keeping the modes sorted by vrefresh before the pixel clock makes the

drm: Add missing bits to drmP.h, required by the Radeon driver

Some of the FreeBSD-specific definitions are moved to drm_os_freebsd.h.
But there's still work to do to clean it up and reduce the diff with
Linux' drmP.h.

drm: Import drm_pcie_get_speed_cap_mask() in drm_pci.c

This comes with several PCI_VENDOR_ID_* defines which should go in a
more central place.

drm: Support gem_open_object() and gem_close_object() callbacks

... in struct drm_driver_info.

drm: In drm_mmap_single, try ttm_bo_mmap_single() before drm_gem_mmap_single()

In drivers such as the Radeon driver, the DRIVER_GEM features flag is
set but TTM is used to mmap buffer object.

drm: Use driver-provided "use_msi" callback to determine if MSI is blacklisted

For now, keep the static array for i915. But eventually, it should be
moved to a callback in the driver itself.

drm: Move definition of EREMOTEIO to drmP.h

It will be used by both i915 and radeon drivers.

Add ERESTARTSYS definition at the same time.

drm: Import drm_dp_helper.c from Linux 3.8-rc3

While here, update drm_dp_helper.h to better match Linux one.

Switch the vm_object mutex to be a rwlock. This will enable in the
future further optimizations where the vm_object lock will be held
in read mode most of the time the page cache resident pool of pages
are accessed for reading purposes.

The change is mostly mechanical but few notes are reported:
* The KPI changes as follow:
- VM_OBJECT_LOCK() -> VM_OBJECT_WLOCK()
- VM_OBJECT_TRYLOCK() -> VM_OBJECT_TRYWLOCK()
- VM_OBJECT_UNLOCK() -> VM_OBJECT_WUNLOCK()
- VM_OBJECT_LOCK_ASSERT(MA_OWNED) -> VM_OBJECT_ASSERT_WLOCKED()
(in order to avoid visibility of implementation details)
- The read-mode operations are added:
VM_OBJECT_RLOCK(), VM_OBJECT_TRYRLOCK(), VM_OBJECT_RUNLOCK(),
VM_OBJECT_ASSERT_RLOCKED(), VM_OBJECT_ASSERT_LOCKED()
* The vm/vm_pager.h namespace pollution avoidance (forcing requiring
sys/mutex.h in consumers directly to cater its inlining functions
using VM_OBJECT_LOCK()) imposes that all the vm/vm_pager.h
consumers now must include also sys/rwlock.h.
* zfs requires a quite convoluted fix to include FreeBSD rwlocks into
the compat layer because the name clash between FreeBSD and solaris
versions must be avoided.
At this purpose zfs redefines the vm_object locking functions
directly, isolating the FreeBSD components in specific compat stubs.

The KPI results heavilly broken by this commit. Thirdy part ports must
be updated accordingly (I can think off-hand of VirtualBox, for example).
