Hi!
This is v4 of [1]

Changes since v3:
 - Slightly tweaked the efidebug argument parsing following Heinrich's 
   suggestion.  Instead of calculating the file device path initially and
   appending the initrd, the 2 two device paths are now calculated 
   independently and concatenated later, allowing us to easier handle the 
   various switches (-i, -b etc)
 - Fixed documentation typo that prevented htmldocs from building
 - Removed [1/6] patch which was already merged

Changes since v2:
 - Lengths checks when interpreting a device path, to make sure we aren't
   going out of bounds
 - renamed efi_get_file_size -> efi_file_size and moved it in efi_file.c
 - Fix uninitialized variable related errors reported by Cppcheck
 - Fixed various error messages for easier end user readability
 - renamed _efi_dp_append() -> efi_dp_append_or_concatenate()
 - Picked up Reviewed-by tags
 - Enabling the protocol by default

Changes since v1:
 - minor coding style fixes from Heinrich
 - changed the DP format. Instead of VenMedia - 0x01 - initrd, we skip
   the 0x01 between VenMedia and the first file. 
 - final device path is stripped in efi_get_dp_from_boot() instead of 
   get_initrd_fp()
 - Fixed comments on documentation
