Brian Swetland 71b934bd5b [bootdata] further movement toward new bootdata headers

- bootloader, kernel, userboot, and devmgr now support FLAG_EXTRA
  for container headers as well as item headers
- bootloader generates new style headers for prepended bootdata
  items when it detects a new style container header
- mkbootfs generates large container headers when generating
  bootdata images with crc32 enabled
- bootloader version bumped to 0.6.0 to mark the point of
  compatibility needed for kernels once we throw the switch
  to use new headers exclusively

What is This?
-------------

This project contains some experiments in software that runs on UEFI
firmware for the purpose of exploring UEFI development and bootloader
development.

Since UEFI images are in PE32+ file format, we require that our binaries be
position independent executables with no relocations. For the most part this
does not require any extra effort on x86-64, but it does mean that you cannot
statically initialize any variables that hold an address. (These addresses may
be assigned at runtime however.)


External Dependencies
---------------------

qemu-system-x86_64 is needed to test in emulation
gnu parted and mtools are needed to generate the disk.img for Qemu
