Since OsLoader will restart from beginning and all memory will be
reclaimed, it is required for Shell library to re-initialize the
global varaibles, for example, command list. Otherwise, the old
memory pointer will be used and cause issues. This patch added the
link list re-initialization in Shell lib. It fixed#253.

Currently, all shell commands are statically defined in header file.
Add shell command registration API to allow include/exclude shell
commands dynamically.
Later, some debug shell commands will be added according to build
mode or debug mask.
- TBD: Sorting shell commands by name

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.

Current implementation assumes serial port is the only input console
device supported. But other input console devices can be added later
on. This patch added a ConsoleInLib to abstract the input console
interfaces. It also added PCDs to control enabled input console
devices.
