Remove some debug messages which were basically left over from when
the code was being developed.
However we leave debug messages where it is printing an external
command that is about to be executed, since those are useful.

If you ran part-get-parttype command on a device which didn't
contain a partition, it used to return the string "loop". This
is an internal representation that parted uses. We should instead
return an error because part-get-parttype makes no sense for
devices which are not partitioned.

Change the part-disk command so it aligns the partition to
64 sectors (instead of 1 or 34 sectors as now). This should
ensure that the filesystem contained within is aligned.

This fixes the following commands when run with RHEL 5-era parted:
get-bootable
get-parttype
part-list
|
| | |
|
| |
|
|
| |
These APIs flesh out further the partitioning API.

Previously we used strtok. However this has the problem that
strtok considers multiple delimiter characters to be like a single
delimiter, eg. "1:::2" would be parsed the same as "1:2". In
other words, the previous code would skip over or fail if there
are empty fields.

This allows us to make the RUN_PARTED macro do something else
along the error path, other than just returning -1.

Change the appliance so PATH includes common directories. Thus
we don't need to hard-code paths to binaries (eg. "/sbin/fdisk")
everywhere.

The RPC stubs already prefix the command name to error messages.
The daemon doesn't have to do this. As a (small) benefit this also
makes the daemon slightly smaller.
Code in the daemon such as:
if (argv[0] == NULL) {
reply_with_error ("passed an empty list");
return NULL;
}
now results in error messages like this:
><fs> command ""
libguestfs: error: command: passed an empty list
(whereas previously you would have seen ..command: command:..)

This commit introduces a generic partition creation interface
which should be future-proof and extensible, and partially
replaces the old sfdisk-based interface.
The implementation is based on parted but is hopefully not too
dependent on the particulars of parted.
The following new calls are introduced:
guestfs_part_init:
Initialize a disk with a partition table. Unlike the sfdisk-
based interface, we also support GPT and other partition
types, which is essential to scale to devices larger than 2TB.
guestfs_part_add: Add a partition to an existing disk.
guestfs_part_disk:
Convenience function which combines part_init & part_add,
creating a single partition that covers the whole disk.
guestfs_part_set_bootable:
guestfs_part_set_name:
Set various aspects of existing partitions.
guestfs_part_list:
List partitions on a device. This returns a programming-friendly
list of partition structs (in contrast to sfdisk-l which cannot
be parsed).
guestfs_part_get_parttype:
Return the partition table type, eg. "msdos" or "gpt".
The following calls are planned, but not added currently:
guestfs_part_get_bootable
guestfs_part_get_name
guestfs_part_set_type
guestfs_part_get_type
