This patch adds support for a debug console on the same port that is used
by SeaBIOS. This makes it easier to debug OVMF, because it does not mix
debug and serial output on the same device. It also makes it easier to
leave some of the debug messages on even in release builds.
To enable it, pass "-debugcon stdio -global isa-debugcon.iobase=0x402" to
QEMU.
The new mechanism is enabled by default, but a regular serial console can
be chosen by adding -D DEBUG_ON_SERIAL_PORT to the build options.

a. Update PciBusDxe module, and move it from IntelFrameworkModulePkg to MdeModulePkg
b. Move IncompatiblePciDeviceSupportDxe module from IntelFrameworkModulePkg to MdeModulePkg
c. Update the related consumes in inf/dsc/fdf

Align the PE32/32+ images in the ROM for XIP (execute in place) images
to function properly following the change in r9327. Also, convert
pre-memory PEIM's to use the TE image format and strip-relocation
data from image. This saves a little space, and provides a sample
usage of TE images.

Previously the code would expect that the PE32 image was in the
first section of the FFS file. This might not be the case if the
PE32 section is forced to be aligned.

Note:
* This only works before ExitBootServices
* For OVMF, variables are only preserved on the disk if there
is a hard disk connected which has a writeable FAT file system.
The Ovmf/Library/EmuVariableFvbLib library will look for the
gUefiOvmfPkgTokenSpaceGuid.PcdEmuVariableEvent PCD to be set to
a non-zero value. If set, it is treated as an event handle, and
each write to the EmuVariableFvb will cause the event to be
signaled.
In this change, the OVMF platform BDS library sets up this event,
and sets the PCD so that after each write to the EMU Variable FVB,
the non-volatile variables will be saved out to the file system.
The end result is that NV variables that are written prior to the
ExitBootServices call should be preserved by storing them on the
disk.

OVMF utilizes EmuVariableFvbRuntimeDxe to provide an emulated
variable firmware volume block device for non-volatile variables.
This allows the VariableRuntimeDxe and FaultTolerantWriteDxe
to function without a real non-volatile backing store.

This driver implements a firmware volume block protocol instance
which is stored in system memory.
The MdeModulePkg/Universal/Variable/RuntimeDxe and
MdeModulePkg/Universal/FaultTolerantWriteDxe drivers make use of
this FVB instance to provide variable services.
This driver links to a PlatformFvb library to allow for
platform specific processing to take place when data is written
to the FVB.

This library provides an interface where variables can be saved and restored
using a file in a file system accessible to the firmware. It is expected
that a platform BDS library will use this library. The platform BDS
implementation can decide which devices to connect and then to attempt to use
for saving and restoring NV variables.

Make use of EMU Variable driver's PcdEmuVariableNvStoreReserved to allow
NV variables to persist a VM system reset. The contents of the NV variables
will still be lost when the VM is shut down, but they appear to persist
when the efi shell reset command is run. (Tested with QEMU 0.10.0.)

QEMU will automatically fill the video BIOS image into memory at the
legacy video BIOS memory location (0xc0000). This code will look
there for a EFI option rom image, and load it if it found. This
allows the video option ROM to be separated out from the main system
firmware image.
QEMU does not appear to emulate the PCI rom expansion method
for making the video BIOS available to the system.

It is not proper for a library implementation to assume the names of function in a parent module.
Instead, they must be designed as the pointers to these two BdsDxe functions and passed in.

Move many libraries to Libraries.common section.
Add basic UEFI_APPLICATION libraries to allow applications
to be easily added to OVMF builds.
