Boris Ostrovsky 3b27981170 pygrub: Fix regression from c/s d1b93ea, attempt 2
c/s d1b93ea causes substantial functional regressions in pygrub's ability to
parse bootloader configuration files.

c/s d1b93ea itself changed an an interface which previously used exclusively
integers, to using strings in the case of a grub configuration with explicit
default set, along with changing the code calling the interface to require a
string.  The default value for "default" remained as an integer.

As a result, any Extlinux or Lilo configuration (which drives this interface
exclusively with integers), or Grub configuration which doesn't explicitly
declare a default will die with an AttributeError when attempting to call
"self.cf.default.isdigit()" where "default" is an integer.

Sadly, this AttributeError gets swallowed by the blanket ignore in the loop
which searches partitions for valid bootloader configurations, causing the
issue to be reported as "Unable to find partition containing kernel"

We should explicitly check type of "default" in image_index() and process it
appropriately.

pygrub is a grub-like bootloader for xen. This tool is to use to boot domU images.

To compile pygrub, you will need the following packages installed:

1) Libraries of ext2fs, which is the following package (depend on your Linux distribution):
	- e2fslibs-dev on Debian based distributions (Debian, Ubuntu, Linspire, Libranet, Xandros, etc...)
	- e2fsprogs-devel on RedHat, Fedora Core
	- libext2fs2-devel on Mandriva/Mandrake
	- e2fsprogs on Gentoo

2) Libraries of reiserfs, which is the following package (depend on your Linux distribution):
	- libreiserfs-dev on Debian based distributions (Debian, Ubuntu, Xandros, Libranet, Xandros, etc...)
	- progsreiserfs-devel on RedHat
	- progsreiserfs on Gentoo
