The default Virtual RAM size for the helper VM used to be 256MB

This can be used to overwrite the size of the virtual RAM that will
be given to the helper VM

Fix a bug where API params like CONFIG_URL or IMG_PASSWORD where
checked and used by scripts other that `create' (e.g. `import' and
`export'). This may lead to errors. The CONFIG_URL may not be valid
after the image creation

Add extra code to check if the image path ends up being outside the
IMAGE_DIR directory

This used to be file://

The variable should only exist in snf-image-update-helper. If the
user wants to overwrite the value, he should create it in
/etc/default/snf-image-update-helper

Rename snf-image-create-fixed-helper script to snf-image-create-helper.
Also remove the command that will create a tar archive of the helper
files under /tmp

When you run snf-image-create-fixed-helper an archive of the fixed
helper is created under /tmp

Move the old snf-image-update-helper to snf-image-create-fixed-helper
and make the new snf-image-update-helper download a fixed helper image
specified by the HELPER_URL variable.

The check for supported hypervisors should only executed by scripts
that comply to the ganeti api.

The script should always exit with an error status after a log_error
command

Add check_helper_rc and check_helper_result functions called by
kvm-common.sh and xen-common.sh.

* Add custom vif script for the helper VM
* Cleanup helper code

This can be used to configure the bridge on which the helper's VM
nic will be attached when using XEN.

Change HELPER_SIZE to 600 and HELPER_SOFT_TIMEOUT to 120

Add a new HELPER_SIZE variable for this purpose. Default size is
hardcoded to 400MB

Remove:
	HELPER_CACHE_DIR
	HELPER_IMG
	HELPER_KERNEL
	HELPER_INITRD
 	TIMELIMIT
Add:
	TIMEOUT

In configure, remove:
	--enable-network-backend
	--with-helper-img
	--with-helper-kernel
	--with-helper-initrd

Modify pithcat to be able to parse and work with URLs of the form:
`pithosmap://hash/size' which are neeed for archipelagos.

Make sure local variables are defined as local before they get assigned.
Having variables get defined and assigned in one line like this:

local var=foo

can sometimes cause problems. For example, this line:

local var=$(false)

will return 0 and the script will not fail if set -x is defined.

snf-image-update-helper will only install a pkg retrieved from the
apt unless -p option is specified.

This can be used to enable or disable the version check between
snf-image-host and snf-image-helper at the end of the update-helper
script.

Using package caches to create the helper image is dangerous now that
snf-image-helper is automatically retrieved.

The files hosted in this directory will be added in the
/etc/apt/preferences.d directory of the helper image before multistrap
runs.

Do not send through the monitor pipe the error messages. They may
contain internal sensitive information. Create a new report_error
function for sending errors through the monitoring pipe.

Helper gets a dummy interface and communication between helper

Support launching helper domain on top of Xen hypervisor under PV mode.

Helper VM becomes hypervisor aware by passing hypervisor=$HYPERVISOR
in the kernel command line and thus acts accordingly (which logging
devices to use, what disk/floppy devices to expect, etc)

We separate all hypervisor specific functions and vars and source them
according to $HYPERVISOR env var.

Due to the fact that multiconsole for PV domains is supported only after
linux kernel 3.2 (Stefano Stabellini tree - branch 3.2-multiconsole-2
git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git

) all
output/error report and logging is done via hvc0.

Helper domain is debootstraped with 2 kernels (linux-image-amd64,
linux-image-xen-amd64) and is booted accordingly.

Floppy is not supported in PV so floppy is passed as another disk.

The images created can run on top of xen-hvm and xen-pvm hypervisor.

Change logging to start with HELPER_MONITOR_ in order to parse it when
having only one console.

multistrap is more flexible allows as to define more that one
repository to retrieve packages from.

if this is set, then snf-image will run in debug mode.
