Release v0.3 work items

[cl91]

Work items for future releases (probaby v0.3). Some of these are moved from v0.2.

• Implement UEFI framebuffer console. This is done in commit 51f224a
• Enable IOAPIC/IOAPICx2
• Port the acpi.sys driver from ReactOS.
• Call the ACPI driver to shutdown the machine. #16
• Implement IRP cancellation #17
• Fix miniport/miniclass driver loading. In the minidriver/driver pair the driver is basically a DLL which is linked into the minidriver. The real driver entry is in the minidriver. This is not needed for fdc.sys but needed for the storage driver stack.
• Port pci.sys. ReactOS has two PCI drivers, bus/pci and bus/pcix, the latter of which is more feature-complete.
• Enable MSI (message signaled interrupts). This is important since interrupt sharing is slow due to the microkernel context switching overhead.
• Port the PCI IDE port driver pair (port pciidex.sys and miniport pciide.sys)
• Port the storage driver stack from ReactOS. This includes the class driver classpnp.sys, class minidrivers (disk.sys, cdrom.sys), ATA port drivers (atapi.sys).
• Implement the on-disk format of the registry
• Implement NtDeleteKey. Note that we need to figure out how to distinguish closing a handle to a key object and deleting the key object from the disk. Perhaps the object manager needs two "delete" routines: a close routine that is invoked the the in-memory object is deleted, and a delete routine that is invoked when the object is deleted from the disk.
