We can't use ShellCommandLineParse as it would error out when the shell was
called with args like "cp -r foo bar", because "-r" is not a recognised shell
option
A different way to avoid some of this manual parsing would be to prepend '^' to
each argument, but that would still require the degree of parsing necessary to work
out which words are part of the command and which are shell options.

This means we can use ShellExecute without thinking which shell
environment is in use. However it still isn't ideal: if
mEfiShellEnvironment2->Execute returns EFI_INVALID_PARAMETER, we can't tell
whether Execute() received an invalid parameter (e.g. ParentImageHandle was
NULL), or whether we tried to execute a command with an invalid parameter
(for example CommandLine "ls -hurdygurdy").

This has no change in the behavior of the LS command, but it removes the printing logic from the main recursive function. This is the first step toward changing the code flow without affecting the look and feel.
The long term goal is correcting the recursion to be more clean and useful to users.

The file format is as below:
<File> := <Variable>+
<Variable> := <Name-Size> <Data-Size> <Name> <GUID> <Attributes> <Data> <Crc32>
Each variable representation in the file has a CRC32 value which can provide a mechanism to detect the file modification.
When any CRC32 is incorrect, dmpstore rejects to load the variables from the file.

This almost completely splits the RunCommand API into sub-routines.
- the ProcessCommandLineToFinal API handles replacing the a found alias and any found environment variables. This will redirect "-?" to "help", if necessary. Upon return, the command line is complete and finalized. It may still have redirection in it, and those will get chopped off later (but no further modifications occur).
- the SetupAndRunCommandOrFile API handles updating and then later restoring StdIn, StdOut, and StdErr (and removing their information from the command line). It will call into RunCommandOrFile.
- the RunCommandOrFile API divides the logic to RunInternalCommand, RunScriptFile, or running an .EFI file directly.
- the RunInternalCommand API handles updating and then restoring Argc and Argv. It will run the internal command in between.
- the SetLastError API handles updating of the environment variable "lasterror"
- the DoHelpUpdateArgcArgv was changed to DoHelpUpdate and now works on the raw command line and not the argc/argv. This allows the processing to be moved earlier.
Note this change has the following positive side effects (this eliminates unnecessary step):
- Argc/Argv are only updated for internal commands (as they are library based)
- no Argv/Argc/StdIn/StdOut/StdErr processing is done for file system changes.
- The ProcessCommandLineToFinal API exists and it's critical to the ability to correctly pre-process split ("|") command lines ahead of time to verify their correctness.
