/** @file
Load File protocol provides capability to load and unload EFI image into
memory and execute it.
Load file protocol exists to supports the addition of new boot devices,
and to support booting from devices that do not map well to file system.
Network boot is done via a LoadFile protocol.
UEFI 2.0 can boot from any device that produces a LoadFile protocol.

the image to be loaded.
@param SourceSize The size in bytes of SourceBuffer.
@param DstBuffer The buffer to store the image.
@param NumberOfPages For input, specifies the space size of the image by caller if not NULL.
For output, specifies the actual space size needed.
