Fix xl shutdown and init / sysconfig behaviour

Fix xl shutdown and init / sysconfig behaviour

[linux]

Hi IanC,

Here are some patches that fix the most important part of the lack of a working shutdown in the default init / sysconfig scripts when using xl.
This patch series does *not* include the --all option, which is also lacking from xl/libxl and is used as "catch all" 
in the xendomains init script during shutdown.

[PATCH 1/3] init/sysconfig scripts: Remove --halt/-H option for shutdown command.
[PATCH 2/3] init scripts: xendomains correct order of options for shutdown command
[PATCH 3/3] xl/libxl: make shutdown accept the long option --wait for -w

[PATCH 1/3] init/sysconfig scripts: Remove --halt/-H option for shutdown command.

[linux]

From: Sander Eikelenboom <linux@eikelenboom.it>

The --halt/-H option for the shutdown command is now pointless,
since linux in a guest treats "halt" and "poweroff" identically.
The option is not implemented in xl / libxl and if supplied causes the command
to fail , so remove it from the init and sysconfig scripts.

This looks good to me but I'd just like to confirm that Free&NetBSD also
treat them the same before I commit it.

shutdown in NetBSD never had a --halt option.
shutdown runs the shutdown procedure and halts the system.
shutdown -p runs the shutdown procedure and then powers off the system.

[PATCH 2/3] init scripts: xendomains correct order of options for shutdown command

[linux]

From: Sander Eikelenboom <linux@eikelenboom.it>

Options for the shutdown command that are supplied behind the domain id are
ignored. In case of the default xendomains init script this means that it will
not wait for the domains to be actually shutdown.

[PATCH v2 3/3] xl/libxl: make shutdown accept the long option --wait for -w

[linux]

From: Sander Eikelenboom <linux@eikelenboom.it>

Make xl/libxl accept the long option --wait for -w to be compatible with xm.
The long options are used in the default init and sysconfig scripts.
