Within function EfiShellGetDevicePathFromFilePath(), when the input
parameter 'Path' string is like:
"FS0:"
It is possible for the below statement:
"if (*(Path+StrLen(MapName)+1) == CHAR_NULL) {"
to read the content 1 byte beyond the string boundary (both 'Path' and
'MapName' will be FS0: in this case).
This commit adds additional checks to avoid this.

PathSize is the number of bytes in PathForReturn buffer so
PathForReturn[PathSize - 1] incorrectly accesses the last
character in the buffer,
PathForReturn[PathSize / sizeof (CHAR16) - 1] should be used.

Old code saves the alias to variable storage without
converting the alias to lower-case, which results
upper case alias setting doesn't work.
The patch converts the alias to lower case before saving
to variable storage.

According to Shell spec 2.2 '-exit' invocation option is used to specify
that after running the command line when launched, the UEFI Shell must

When ">v" is used to redirect the command output to environment
variable (e.g.: "echo xxx >v yyy"), we only called SetVariable()
to update the variable storage but forgot to update the cached
environment variables in gShellEnvVarList.
When updating the variable storage, the existing code unnecessary
saved the ending NULL character into variable storage.
The patch fixes all the above issues.

The destination GUID comes first; from
"MdePkg/Include/Library/BaseMemoryLib.h":
> GUID *

> CopyGuid (
> OUT GUID *DestinationGuid,
> IN CONST GUID *SourceGuid

Here "NewGuid" is the GUID looked up by GetGuidFromStringName(), and
"Guid" is where EfiShellGetGuidFromName() has to propagate that result to.

As per ECR 1349 change in UEFI Shell Specification 2.2, expanding
a special output file name to include "NULL". Previously it only
supported "NUL" as a special output file and it was case sensitive.
With this change both "NUL" and "NULL" are special output file and
checked as case insensitive.

According to the latest shell spec, in function FindFiles(),
when no files were found, it should return EFI_NOT_FOUND.
But current codes don't follow the spec.
This patch is to fix this issue.

UEFI Shell 2.x cannot recognize whether a .EFI file is an application or
a driver. This means when we typed in a driver image in Shell command
line, Shell will load the driver image and try to run the entry point
function of the driver.
This patch check the ImageCodeType to fix the issue.

Currently UEFI Shell reads variable storage to get the environment
variables every time running a new command. And reading(writing)
UEFI variables is a high cost operation on most platforms. In order
to enhance the performance this patch read the variable storage once
and cache the environment variables in memory. Every further 'set'
command will save the variable not only to Shell cache, but also the
flash variable storage.

When the FvSimpleFileSystemDxe module is included in a platform,
Simple File System Protocols are produced for firmware volumes(FV)
that do not have the same style device paths as file systems with
file names. The ShellPkg has an assumption that the device path
contains device path nodes of type MEDIA_FILEPATH_DP and generates
an ASSERT() if any other device path nodes are encountered. This
change removes the ASSERT() condition and instead returns NULL that
means EfiShellGetFilePathFromDevicePath() can not convert the
device path nodes that represent the file path to a Unicode string.
