SBL Shell allocated memory during the command registeration phase.
However, these memory is not de-allocated after Shell exits. This
patch added code to de-allocate the memory. It also rearranged the
code a little bit so that function declarations are not required
any more.

Soemtimes when JTAG based debug is not available, it might be easier
to have Shell access in earlier stage to check lots of platform
settings. Today it is impossible because full Shell has lots of other
dependencies which might not satisfy in early stage. This patch added
a PCD PcdMiniShellEnabled to build a mini Shell with very few
dependencies. This mini Shell can be used in early debug phase for SBL.
To use it, add the following to override the PCD for a specific stage
in BootloaderCorePkg.dsc.
EX:
$(PLATFORM_PACKAGE)/Stage1B/Stage1B.inf {
<PcdsFeatureFlag>
gPlatformCommonLibTokenSpaceGuid.PcdMiniShellEnabled | TRUE
...
}
Then include ShellLib.h in stage C code and add ShellLib in related
stage INF file. If adding it into Stage1A, it needs to be after the
Stage1A banner print out.

This patch removed global variable usages in ShellLib. It is
required when running Shell in early stage from flash. In this
case global variable is read-only. All memory should be allocated
from stack or heap.

This provides basic insertion sort API for Linked List. As part of change,
this insertion sort is used for PCI BAR calculation by its alignment
and for shell commands list by its name.

This patch added command line history upport in SBL Shell. It makes
it easy to run a previous command using Up/Down arrow key.

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.
