Hello,

First patch adds support for GRUB_FILE_SIZE_UNKNOW file size in grub_file_read 
and grub_file_seek functions. 

Second and third add GRUB_FILE_SIZE_UNKNOW support for gzio and xzio when 
dealing with not easily seekable files.


Should be usefull for reading compressed files over pxe. 

Testing and comments are welcome :)
