Ensure atomic creation of a cached appliance
Cached appliances are discovered by their predictable path. Previously we were
creating a cached appliance directly in this predictable path. This had at least
2 undesirable effects:
* Interrupting appliance creation would leave a corrupt appliance
* 2 processes could simultaneously attempt to create the same appliance, causing
corruption.
This patch causes the cached appliance to be created in a temporary directory,
and then renamed to the predictable path. As rename is an atomic operation, this
makes the whole creation atomic.
This patch also changes the predictable path to have a prefix of 'guestfs.'.
This will make it simpler for system administrators to clean up old cached
appliances.

Call febootstrap-supermin-helper using the new -u and -g options
Use febootstrap-supermin-helper's new -u and -g command line options to setuid,

This resolves an issue with the generation of the cached appliance checksum. The
checksum was being generated by a call to febootstrap-supermin-helper through
popen(). Unfortunately, a bash misfeature meant that euid would be reset to uid,
and the checksum was generated for uid, not euid. When virt-v2v is writing to a
RHEV target, uid == 0 and euid == 36, which resulted in a cached appliance being
created for root with permissions for uid 36.

resize: Specify format of input, output disk (RHBZ#642934,CVE-2010-3851).
This adds two new options: --format specifies the format of the
input disk, and --output-format specified the format of the output
disk.
Requiring the format of the output disk seems a bit strange at first:
after all, this is the disk that the virt-resize user has to create.
However it is needed because we sometimes reopen this disk, after
copying data over the first sector, and in theory a raw-format guest
could write a qcow2 header here and have it copied to the output
disk, which we would subsequently reopen.

Sys::Guestfs::Lib is changed in two ways: firstly we take the format
string from libvirt and pass it to add_drive_opts. Secondly we allow
an extra format => parameter to open_guest which allows the
format to be specified for disk images.
All the tools are changed to add an extra --format parameter allowing
the format to be specified for direct disk images.

generator: Optional arguments, add-drive-opts (RHBZ#642934,CVE-2010-3851).
This large commit changes the generator so that optional arguments
can be supported for functions.
The model for arguments (known as the "style") is changed from
(ret, args) to (ret, args, optargs) where optargs is a more limited
list of arguments.
One function has been added which takes optional arguments, it is
"add-drive-opts", modelled as:
(RErr, [String "filename"], #required
[Bool "readonly"; String "format"; String "iface"]) #optional
Note that this function is processed in the library (does not go over
the RPC protocol to the daemon). This has allowed us to simplify
the current implementation by omitting changes related to RPC or the
daemon, although we plan to add these at some point in the future.
From C this function can be called in 3 different ways as in these
examples:
guestfs_add_drive_opts (g, filename,
GUESTFS_ADD_DRIVE_OPTS_READONLY, 1,
GUESTFS_ADD_DRIVE_OPTS_FORMAT, "raw",
-1);
(the argument(s) between 'filename' and '-1' are the optional ones).
guestfs_add_drive_opts_va (g, filename, args);
where 'args' is a va_list. This works like the first version.
struct guestfs_add_drive_opts_argv optargs = {
.bitmask = GUESTFS_ADD_DRIVE_OPTS_READONLY_BITMASK,
.readonly = 1,
}
guestfs_add_drive_opts_argv (g, filename, &optargs);
This last form lets you construct lists of optional arguments, and
is used by guestfish and the language bindings.
In guestfish optional arguments are used like this:
add-drive-opts filename readonly:true
In OCaml these are mapped naturally to OCaml optional arguments, eg:
g#add_drive_opts ~readonly:true filename;
In Perl these are mapped to extra arguments, eg:
$g->add_drive_opts ($filename, readonly => 1);
In Python these are mapped to optional arguments, eg:
g.add_drive_opts ("file", readonly = 1, format = "qcow2")
In Ruby these are mapped to a final hash argument, eg:
g.add_drive_opts("file", {})
g.add_drive_opts("file", :readonly => 1)
g.add_drive_opts("file", :readonly => 1, :iface => "virtio")
In PHP these are mapped to extra parameters. This is not quite
accurate since you cannot omit arbitrary optional parameters, but
there's not much than can be done within the limitations of PHP
as a language.
Unimplemented in: Haskell, C#, Java.
