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.

Increase the value of USB_GENERAL_DEVICE_REQUEST_TIMEOUT from
50 milliseconds to 100 milliseconds. This provides a work around
for slower USB hubs and devices.

Impaction:
There should be no impact unless code has been written that tests a constant or variable of type EFI_STATUS to be less than 0, or tested it against a negative value. This most likely have not been done.

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.

PcdFlashNvStorageFtwWorkingBase and PcdFlashNvStorageFtwSpareBase are
now updated each time an FVB instance is installed. This allows the
PCDs to be set at runtime at any time before the FVB is installed.

1. TapeIo TAPE_HEADER is rename to EFI_TAPE_HEADER
2. Add IN modifier for parameter Direction and Type of TapeIo.TapeSpace
3. HII package header EFI_HII_DEVICE_PATH_PACKAGE is renamed to EFI_HII_DEVICE_PATH_PACKAGE_HDR.
4. HII package header EFI_HII_FORM_PACKAGE is renamed to EFI_HII_FORM_PACKAGE_HDR.
