Mender is an A/B partitioning scheme
for Linux OSes. Adding initial support
for specifying the root partition label
that should be used. Later on the root
partition label should be acquired based
on the value of the env files stored in
the EFI/FAT32 partition of the boot media.
Also fix misspellings.

This patch added a ContainerLib to support load and location a
component from a specified container. It copies the component
from flash to memory, authenticate it, and then decompress it if
required. It can also be used to support load component from flash
map in SBL stage2 or payload, such as payload or e-payload.

For the pre-OS payload/checker pass in a parameter
that contains additional information for heap space,
heap address, and additional CPU registers that may
need to be set before the pre-OS payload/checker
passes control to the OS.

Some OSes may require a pre-OS checker executable
to run before actually jumping to the OS. Add
support for this pre-OS checker loading & execution
as part of the OS Loader payload when it is compiled
as an FV and when ENABLE_PRE_OS_CHECKER option is
enabled in BoardConfig.py (per the following command):
SblBuild.py build <plat> -p OsLoader.Fv:LLDR:Lz4
The pre-OS checker entry point takes in a single
parameter which provides the CPU boot state that
should be loaded once jumping into the OS for the
pre-OS checker to launch after it finishes execution
(e.g. pre-OS checker does not return to Slim Bootloader).

This patch enabled DISABLE_NEW_DEPRECATED_INTERFACES build option by
default so that the deprecated APIs cannot be used in SBL source tree.
It is to enhance the coding for security.

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.
