fixed to build under IPF. 

Refactored some commands into FileHandleLib since they are used in many binaries.
Added .h for GUID that was missing.
Added PCD for initialization of shell apps and shell itself in shell library interaction.

/**
This function reads information from an opened file.
If FileHandle is not a directory, the function reads the requested number of
bytes from the file at the file’s current position and returns them in Buffer.
If the read goes beyond the end of the file, the read length is truncated to the
end of the file. The file’s current position is increased by the number of bytes
returned. If FileHandle is a directory, the function reads the directory entry
at the file’s current position and returns the entry in Buffer. If the Buffer
is not large enough to hold the current directory entry, then
EFI_BUFFER_TOO_SMALL is returned and the current file position is not updated.
BufferSize is set to be the size of the buffer needed to read the entry. On
success, the current position is updated to the next directory entry. If there
are no more directory entries, the read returns a zero-length buffer.
EFI_FILE_INFO is the structure returned as the directory entry.
@param FileHandle the opened file handle

the number of bytes written.
