BGRT can be used by bootloader to pass logo to OS. But BGRT can
only support 24bit or 32bit BMP format. If the bootloader uses
other bit format or indexed color format, the image has to be
converted before passing it to BGRT. This patch added support
to convert other BMP image format into 32bit format required by
BGRT.
This has been tested with Windows on Leafhill board. The SBL
logo was dispalyed properly while booting Windows.

This patch added new DrawFrameBuffer interface. It will draw the
framebuffer from a VGA like text buffer. Payload can use this
to sync its own text buffer onto framebuffer screen. It aslo added
extend ASCII char support so that some table char can be displayed.

There are cases where temporary memory is required in stages. Since
MemoryAllocationLib instance for stages has no de-allocation function,
it needs special handling. This patch added temporary memory management
into standard MemoryAllocatoinLib interface.

Current implementation of splashing a BMP image to the
display requires the allocation of a temporary buffer
to store the BMP image into a GOP Blt friendly format
that can then be used to splash the image to the display.
Instead of using a buffer for the whole image we can
allocate a smaller buffer to splash one line at a time
since splashing is already performed one line at a time.
Also fix a small print message regarding frame buffer
format.

This patch simplifies the GraphicsLib code and adds an abstraction layer
for printing to a virtual "console," through the familier
ConsoleWrite(buffer, len) style function call.
ConsoleWrite can be configured to output to either the serial port, or
the display framebuffer, or both. This primarily enables the command
shell to be used with a display and keyboard.
