fdisk menus:
- driven by menu and menu_entry structs
- supports normal and expect mode
- supports multiple independent menus
- supports menu separators to make output more readable
- allows to exclude by whole menu or menu entries by label type

- define per label menus
- per menu callback
- sensitive only to keys defined in the currently printed menu

agetty: add \S to output /etc/os-release data
This patch allows to use a new \S or \S{VARNAME} sequence in the
/etc/issue file. The sequence prints data from /etc/os-release. The
reason is to keep /etc/issue file distribution and release
independent.
The \S{ANSI_COLOR} is converted to the real terminal escape seq.
For example:
\S
Kernel \r on an \m (\l)
or more complex example:
Welcome to \S{ANSI_COLOR}\S{NAME}\e0m \S{VERSION}
Report bugs at \S{BUG_REPORT_URL}.
See http://www.freedesktop.org/software/systemd/man/os-release.html

libblkid: don't use UUID= for xfs external log

libblkid: populate jbd LOGUUID in addition to UUID
The LOGUUID is alias for UUID, this alias is necessary to standardize
the tag name (we want to use the same tag LOGUUID= for all external
logs on all filesystems).
Note that for another filesystems (e.g. xfs) we have to differentiate
between the journal and filesystem uuids to avoid collisions, because
both devices use the same uuid.

libblkid: Detect external XFS log device
Detects external XFS log devices with a minimum size of 10MB. It's possible to
craft a smaller log, but that would be very unlikely; it'd require a small XFS
filesystem and an intentionally small log, which would defeat the performance
goal of an external log in the first place.

This happen because oversight when 'exitval' gets to be set. By clance,
one might expect main() to call next() which will return value for
'exitval'. That assessment misses later call chain main() -> display()
-> get() -> next(), which in reverse should return correct value for
'exitval'.
It was mentioned in util-linux maillist that Ondrej Oprala is working on
major renewal of the hexdump . That in mind it seems best to simply to
revert the global 'exitval' and avoid conflict with Ondrej's work.

su: suppress PAM info messages for -c or non-login sessions
The 'Last login:' messages from PAM lastlogin module is unexpected
for non-login sessions or when -c <command> executed.
For example:
$ su - -c id
Last login: Wed Jul 24 08:36:28 CEST 2013 from dhcp-25-161.brq.redhat.com on pts/18
uid=0(root) gid=0(root) skupiny=0(root)
this makes 'su' useless in scripts.
This patch suppress all PAM_TEXT_INFO messages for -c and for
non-login session ('-' is not specified) after pam_authenticate() and
pam_acct_mgmt().
Note that the new PAM conversation function checks the first message
in the msg[] array only. It seems good enough as PAM internally uses
pam_info() function that does not use multiple messages for one conv
call.

* pages : discard freed pages before they are reused.
