[Xen-devel] [PATCH] reworked lomount

["Charles Coffing" <ccoffing@xxxxxxxxxx>]

This patch started out as fixing a warning (due to system()'s return
value not being used).  Then I realized if lomount functioned well it
could be a replacement for kpartx in domUloader (or whatever the
combined pygrub+domUloader story turns out to be), so I gave it a closer
look.

Changes:
- Fixed several overflows, off-by-one, and uninitialized variables.
- Added well-defined exit codes.
- Proper handling of system()'s return value.
- Errors parsing partition table cause it to stop now.
- etcetera...

Tested on 32 and 64 bit, with valgrind, with physical disks and disk
images.

Please apply to xen-unstable.
