By design, BootloaderCommonPkg should not refer to
BootloaderCorePkg. Hence removed those references in
the .inf files in Common pkg.
Moving SmbiosInitLib to Core pkg as it is a core feature.

Users might want to have some parameters that can be set
from UEFI environment. UEFI NVRAM variables provide a way
to achieve this functionality. And they require these vars
to be read from bootloader.
This patch provides a library to get read access to the
UEFI variables stored in NV region. The driver was ported
from MdeModulePkg\Universal\Variable\Pei @ EDKII Open Source.

This patch splitted LoadBzImage() into two functions. One is just
for kernel loading. The other one UpdateLinuxBootParams() is for
Linux boot parameter updates. It is required to do so because when
kernel loading in Stage2 is enabled the loading occurs before all
HOBs are finalized. The Linux boot parameters depend on HOBs to fill
correct information, such as frame buffer. With this patch, the boot
parameters can be updated at the very end.

OsLoader has the capability to boot a Linux kernel. However, to support
LinuxBoot type of payload, it is required to load kernel in Stage2. This
patch abstracts the standard Linux loading logic into common LinuxLib
class so that it can be linked in Stage2 or Payload such as OsLoader.
A new PcdLinuxPayloadEnabled is introduced to control if this feature
should be enabled or not.
To boot a Linux kernel from Stage2, it is required to put the command
line file and kernel image into the EPAYLOAD container during the build.
And the PayloadId CFGDATA needs to be set to 'LINX'.
For example:
python BuildLoader.py build qemu
-p OsLoader.efi::Lz4;vmlinuz:LINX:Dummy;cmdline.txt:CMDL:Dummy
vmlinuz and cmdkube.txt need to be copied to PayloadPkg/PayloadBins
folder. If kernel size cannot fit into EPAYLOAD, EPAYLOAD_SIZE in
BoardConfig.py needs to be adjusted accordingly.

This patch enabled container use case for EPAYLOAD loading.
It also switched to use LoadComponent() API for Stage2 and
payload loading. It simplified the code flow. An example in
QEMU was added to demonstrate on how to add a container in
build and load it in Stage2 code.
To define a container layout, it is required to provide
GetContainerList() in BoardConfig.py. Then in stage or payload
code, LoadComponent() can be used to load a component from the
container.

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.

FileSystemLib provides generic interfaces to access file system and
its files as a abstraction of FatLib/ExtLib.
- Added CloseFileSystem
If there are opened files in a specific filesystem, those files
will be de-allocated in CloseFileSystem.
- Added OpenFile/GetFileSize/ReadFile/CloseFile
The ReadFile() does not allocate any memory for the file content.
The caller of OpenFile() MUST allocate necessary memory before
calling ReadFile().

This patch will add support for updating multiple firmwares
using a single capsule image.
Following modifications are made for existing firmware update flow
1) Gather and validate capsule image
2) State Machine will be set to capsule processing state.
3) Signature of the capsule image is now stored in reserved region
During each reboot until the end of firmware update, stored signature
will be compared against the capsule image signature to make sure
capsule image is not modified until the end of firmware update.
4) Process Capsule image to gather firmware images
5) Each Firmware image information will be stored in reserved region
using FW_UPDATE_COMP_STATUS. Update pending will be marked to
update pending state indicating that this image is not processed.
6) Firmware update will use the reserved region comp structures starting
with the first image with update pending state, update the comp update
pending field to processing and applies the image. After the update, pending
field will be updated to Done and updates the status of the update in the
component structure and moves on to next image found.
7) After all the component structure in the reserved region updating pending
field are set to Done. Firmware update mode is exited.

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.

Current SBL depends on GEN_CFG_DATA.PayloadId to determine which payload
to boot if multiple payloads exist. With this patch, when PayloadId is
set to "AUTO", QEMU will use the QEMU command line parameter
'-boot order' to determine which payload to boot.
For example, adding '-boot order=dba' in QEMU commadn line will boot to
UEFI payload. This provides a simple way to test different payloads using
the same SBL image.
