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 added a simple parser for grub.cfg to make it easy to boot
Ubuntu ISO image using OsLoader payload. Without it, it is required to
copy vmlinuz/initrd to root directory and create a config.cfg to list
the kernel boot command line in order to boot the ISO image. This patch
makes it possible to boot the original Ubuntu ISO (16.04 or 18.04)
directly. It provides better user experience for people who wants to
try out SBL.
Please note, same as before, when verified boot is enabled, only debug
build will support this feature. Release build will disable this feature
due to security concern, please use IAS image boot mechnism instead.

This is a feature implementation to enabled chained payloads loading
for UEFI. Current SBL boot flow requires UEFI payload to be built in
flash in order to boot UEFI payload. However, for convenience, if
somebody just wants to try UEFI payload, it is better to allow them to
chain-loading the UEFI payload from media devices such as USB, SATA, etc,
and then boot to UEFI payload directly. This patch enabled this feature.
The new supported boot flow is: SBL->OsLoader->UefiPayload->OS. The
same applies to other ELF/PE32 based other payloads.
To do this the UEFI payload needs to be packed into IAS image using
iasimage script. The command line is as below:
python iasimage.py create -d TestSigningIasPrivateKey.pem UefiPld.fd
-o iasimage.bin -i 0x30000
Please use the latest iasimage script from
http://github.com/intel/iasimage

In order to support ELF format payload in Stage2, ElfLib is separated
from MultibootLib.
Additionally,
- Load ONLY Executable/Loadable segments
- Keep LoadElfSymtab function for future use
- Mark ELF syms flag as 'not supported' in MultibootInfo

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.

This patch implemented USB keyboard library and added it as an
input console device. It can be enabled by setting BIT1 in
self.CONSOLE_IN_DEVICE_MASK in BoardConfig.py. By default, it
will be disabled for performance and size consideration.
Test has been done on APL Leafhill board. USB keyboard can work
in Shell.
