The >> operator redirects stdout to a file, using append mode and unicode
encoding. Write the BOM when redirection happens to a new file (which
starts out empty).
This makes the >> operator behave similarly to the > operator, when the
redirection target doesn't exist originally:
OutUnicode && OutAppend && FileSize == 0 // >> to new unicode file
vs.
OutUnicode && !OutAppend // > to any unicode file
(Note that (FileSize == 0) is equivalent to "new file" in this context,
due to the earlier "Check that filetypes (Unicode/Ascii) do not change
during an append".)

The function InternalShellExecuteDevicePath() did not differentiate an error occuring during the preparation of an image and an error occurring during its execution.
A use case of the issue was when a EFI application was called in a EFI Shell script. If the EFI application was returning an error then the NSH script stopped its execution. While the EFI Shell specification says the script should continue its execution (see 4.2 Error Handling).

ShellCommandIsOnAliasList is case insensitive, but GetAlias and SetAlias use the
UEFI variable services, which are case sensitive.
Force alias names to lowercase to get around this.

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.
