Current implementation only supports the case that ELF file doesn't reload.
If the ELF file has to be reload (e.g.: to meet alignment requirement), SBL
need copy it to a different location and run.
Recently EDKII updated universal payload ELF image link script, and the new
ELF text alignment was changed to 0x1000 from 0x40. Mostly the default file
load location could not meet this requirement. So enhancement SBL to copy
it to a new location for this case.

Currently, loading an ELF image will relocate the image (to its
preferred load address) only if there is at least one ELF segment
that is not completely contained in the file loaded (i.e. the memory
segment size is larger than the size inside the file. This behavior
is generally triggered by the segment that contains the .bss section).
Consequently, images that contain initialized data only (e.g. QNX IFS
files) don't get relocated, and will usually crash when jumping to the
image entry point.
This change checks whether the ELF image is already loaded at the
preferred address, and forces image relocation if not.

Convert the line endings stored for all text files in the repository to
LF. The majority previously used DOS-style CRLF line endings. Add a
.gitattributes file to enforce this and treat certain extensions as
never being text files.
Update PatchCheck.py to insist on LF line endings rather than CRLF.
However, its other checks fail on this commit due to lots of
pre-existing complaints that it only notices because the line endings
have changed.
Silicon/QemuSocPkg/FspBin/Patches/0001-Build-QEMU-FSP-2.0-binaries.patch
needs to be treated as binary since it contains a mixture of line
endings.
This change has implications depending on the client platform you are
using the repository from:
* Windows
The usual configuration for Git on Windows means that text files will
be checked out to the work tree with DOS-style CRLF line endings. If
that's not the case then you can configure Git to do so for the entire
machine with:
git config --global core.autocrlf true
or for just the repository with:
git config core.autocrlf true
Line endings will be normalised to LF when they are committed to the
repository. If you commit a text file with only LF line endings then it
will be converted to CRLF line endings in your work tree.
* Linux, MacOS and other Unices
The usual configuration for Git on such platforms is to check files out
of the repository with LF line endings. This is probably the right thing
for you. In the unlikely even that you are using Git on Unix but editing
or compiling on Windows for some reason then you may need to tweak your
configuration to force the use of CRLF line endings as described above.

Universal Payload uses ELF format. As a result, the ELF loading
library has been enhanced to handle more complicated cases. The
Universal Payload library added an abstract layer on top of
ELF lib to make it easer to use by SBL. OsLoader and Stage2 were
modified to work with the new library interfaces.

In order to sync up with EDK201911 stable release, it is required
to add missing header files in the INF file. Otherwise, the build
will throw warnings. This patch added the missing headers in INF
files.

The previous implementation has a little confusion in license header.
To avoid further annoying, simply re-implement ElfLib.
- 32bits, little-endian, executable elf only supported
- elf32.h/elf_common.h from BaseTools/Source/C/GenFw
- LoadElfImage() interface changed

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
