To avoid flickers, PyGRUB has to avoid spurious ncurses refresh as
much as possible, in particular before the complete screen is drawn,
and eventually call doupdate last.

Add support to pygrub and libfsimage to boot ZFS root filesystems.
Boot argument of zfs-bootfs is set to describe ZFS root pool and
boot filesystem object number. Boot argument bootpath is set to
describe the virtual device root mirror components.

If there are a large number of kernel images configured in grub.conf
there will be too many to fit in the limited size pygrub display. This
patch fixes this so that the list of kernels scrolls as needed.

Protect pygrub from possible malicious content in guest grub
config file. This fixes CVE-2007-4993. Original patch from
Jeremy Katz, I updated to close 2 remaining issues pointed out
by Christian and Keir, and to use setattr(self, ...).

- xend forwards console traffic between the running bootloader and a pty
which it writes to the store so the xenconsole client can see it.
- the xenconsole client handles the domain's console pty changing.
- xm create no longer runs the bootloader.
- pygrub gets '-i' option to explicitly request an interactive session.
- xend unlocks the domain list during bootloading so that "xm console"
can see the domain and attach to its console pty.

It's also useful for specifying temporary changes etc.

intended. Changes include:
* Addition of basic command line mode much like grub's so that you can
boot things without having them specified in the config file
* Edit/append mode for modifying kernel command lines, etc
* Fix handling of case where the grub config didn't have a default
specified

As reported in the thread:
http://lists.xensource.com/archives/html/xen-users/2006-03/msg00721.html,
pygrub does not open ext2 file systems in partitioned images or sub
partitions on e.g. CentOS/RHEL 4, because e2fsprogs ext2fs_open does not
support an offset into the file to be opened.
With this patch, the error is correctly reported instead of a generic
"unable to open file" (and leaving the user searching in the dark).

if it can't figure out partitions and filesystems. This then makes it
balloon to absurd sizes. Make this only happen if you pass a debugging
flag

a) a couple of variables were referenced wrong
b) fix using arrow keys in the menu to act correctly
c) and look for grub config properly for /boot partition

to support having reading the boot loader config when you're using a
whole disk (eg, file:/root/disk.img,xvda,w) as opposed to just a
partition.
This reads the partition table in the MBR to find the active partition
and then passes that offset down into the filesystem reading code.

- pygrub/README provides information on packages needed to compile pygrub
- support reiserfs {2,3} filesystem
- dynamically build modules based on which filesystem libraries the
system has (proposed by Jeremy)
- pump up pygrub to version 0.2

Apply Nguyen's patch:
- extend filesystem abstraction by adding file_exist() method. this
method is used to check for existent of a file given its name. now
ext2fs implements this method.
- pygrub opens and parses /boot/grub/menu.lst or /boot/grub/grub.conf,
in that order.
- add /usr/lib/python to system path (see pygrub). without this
change, pygrub cannot find grub python package.
- remove few blank lines
