CreateFileInterfaceMem(). Free SplitStdIn after the swap to fix
the memory leak.
2) In RunSplitCommand(), SplitStdOut is checked for equality with
StdIn. This cannot happen due to the if-check within the swap.
Hence remove it.
3) UefiMain() doesn't free SplitList. Delete all list entries and
reinitialize the list when in DEBUG. This does not include the
CreateFileInterfaceMem()-allocated SplitStd mentioned in 1), so

Currently UEFI Shell reads variable storage to get the environment

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

UEFI Shell scandalizes the help message in spec level so that a standalone
UEFI shell application can never get "-?" switch, instead the Shell core
(interpreter) detects the "-?" and finds .MAN file for that shell
application in certain spec defined paths, then show the help extracted
from that .MAN file.
But it means distributing a UEFI shell application not only means
distributing a .EFI file but also distributing a .MAN file. If the text
formatted .MAN file is corrupted (edited by user by mistake), or is
missing (deleted by user by mistake), no help will be shown to user.
So this patch enhance the Shell to make it support finding help message
imbedded in resource section of application image.

Fix various errors when piping a UNICODE or ASCII file to a simple shell application that reads standard input and writes it to standard output.
1) When the memory file is created by CreateFileInferfaceMem() to capture the pipe output, no UNICODE BOM is written to the memory file. Later, when the memory file is read by the application using ShellFileHandleReadLine(), the function indicates that the file is ASCII because there is no BOM.
2) If the file is piped as ASCII, the ASCII memory image is not correctly created by FileInterfaceMemWrite() as each ASCII character is followed by '\0' in the image (when the ASCII data is written to the memory image, the file position should only be incremented by half the buffer size).
3) ShellFileHandleReadLine() does not read ASCII files correctly (writes to Buffer need to be cast as CHAR8*).
4) FileInterfaceMemRead() and FileInterfaceMemWrite() as somewhat hard to read and difficult to debug with certain tools due to the typecasting of This. Added a local variable (MemFile) of the correct type to these functions and used it instead of This.
Enhancement: ShellFileHandleReadLine() now returns EFI_END_OF_FILE when appropriate.

Prior to this change, the shell would not use a MAN file if the Title Header line was not strictly formatted.
For example, if the case of the command name in the file was not exactly the same as the case of the command name as typed by the user,
the MAN file would not be used. Also, extra whitespace on the line would also cause the shell to ignore the MAN file.
This change allows "extra" white space and ignores case when looking for the command name.
It also ignores any path information for cases where the user enters a relative or absolute path to the EFI file.

After this change 'EFI_SHELL_PROTOCOL.GetCurDir()' and 'UefiShellLib.ShellGetCurrentDir()'

This patch has updated all the code in EDKII to make them depend on the new behavior.
Developers should check whether 'GetCurDir()' and 'ShellGetCurrentDir' are used in their source code.
