The field name "ModeNumber" in QEMU_VIDEO_MODE_DATA is misleading -- it is
not immediately obvious whether this field carries a client-visible mode
number, in the GOP sense, or an internal, card type specific mode index.
After checking all references, rename the field to "InternalModeIndex".
Also, when filling in the card type independent QEMU_VIDEO_MODE_DATA array
from the card type specific mode array, distinguish the GOP mode number
from the internal mode index in the debug message.
This patch effects no functional changes.

Currently, QemuVideoGraphicsOutputQueryMode() reports EFI_NOT_STARTED when
this boolean field is set.
However, QemuVideoGraphicsOutputQueryMode() is only available to callers
after the GOP interface has been installed. That in turn implies that the
following partial call tree has succeeded without errors:
QemuVideoControllerDriverStart()
QemuVideoGraphicsOutputConstructor()
QemuVideoGraphicsOutputSetMode(... 0 ...)
HardwareNeedsStarting = FALSE
InstallMultipleProtocolInterfaces(... GOP ...)
That is, when QemuVideoGraphicsOutputQueryMode() is reached,
HardwareNeedsStarting is always FALSE.

In QemuVideoControllerDriverStart():
- remove redundant zero-initialization of:
- Private->Handle (2 locations)
- Private->GopDevicePath (when at devpath end)
- remove fields used for error handling only:
- PciAttributesSaved
- tigthen scope of temporaries:
- MmioDesc
- AcpiDeviceNode
- supplement missing error checks:
- AppendDevicePathNode() can fail with out-of-memory (2 locations)
- when installing GopDevicePath
- retval of QemuVideoGraphicsOutputConstructor() (can justifiedly fail
with out-of-resources)
- plug leaks on error:
- free GopDevicePath (AppendDevicePathNode() allocates dynamically)
- uninstall GopDevicePath
- free Private->ModeData
- call QemuVideoGraphicsOutputDestructor()
- uninstall GOP
In QemuVideoGraphicsOutputConstructor(), called by Start():
- supplement missing error checks:
- QemuVideoGraphicsOutputSetMode() retval (it can fail with
out-of-resources)
- plug leaks on error:
- free Mode->Info
- free Mode
In QemuVideoCirrusModeSetup() and QemuVideoBochsModeSetup(), both called
by Start():
- supplement missing error checks:
- AllocatePool() can fail in both
In QemuVideoGraphicsOutputDestructor(), called by Start() on the error
path:
- plug leaks:
- free Private->LineBuffer, which is allocated in
Start() -> Constructor() -> SetMode()
In QemuVideoGraphicsOutputSetMode(), called by Start() indirectly:
- remove redundant zero-assignment to:
- Private->LineBuffer

The qemu standard vga has a MMIO bar in qemu 1.3+.
Use it if available.

Move to a table-driven hardware detection. Add a table with PCI IDs,
card name and variant enum. Use the table for hardware detection and
initialization. Rename Cirrus-specific data and code to carry "cirrus"
in the name.

This driver provides a UEFI Graphics Output Protocol (GOP) driver
for the QEMU Cirrus VGA hardware. It enables 24-bit color,
and uses the standard 32-bit GOP pixel format whenever possible.
