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

It would complain that NEED_AUG macro was defined but not used.

This fixes support for NTFS, and adds support for:
- reiserfs
- btrfs
- GFS and GFS2
- JFS
- HFS and HFS+
- NILFS
- OCFS2 (disabled)
We don't enable OCFS2 by default, because it pulls in about
140 extra packages into the appliance.
GFS & GFS2 default to single node (no lock manager etc).

When debugging (ie. LIBGUESTFS_DEBUG=1 & verbose flag set in daemon)
always reflect any stderr output from commands that we run to
stderr of the daemon, so it is visible.
Previously if stderror == NULL in command*, stderr output was
just eaten and discarded which meant useful error messages could
be lost.

This adds new variations of the command*() functions which
take a 'flags' argument. Currently the only flag available
is defined as follows:
COMMAND_FLAG_FOLD_STDOUT_ON_STDERR: For broken external commands
that send error messages to stdout (hello, parted) but that don't
have any useful stdout information, use this flag to capture the
error messages in the *stderror buffer. If using this flag,
you should pass stdoutput as NULL because nothing could ever be
captured in that buffer.
This patch also adds some documentation for command*()
function.

This is a hack, but GHC doesn't like it if we have a symbol
with the same name as one in the Haskell Prelude. Therefore
we much hide the corresponding symbol in the Prelude when
building this module.

I'm not sure why these dependencies exist, but they cause the
appliance to be updated every time the generator runs, which
appears to be unnecessary.

With sparse you can make sparse files, which is fun because you
can experiment with really large devices:
><fs> sparse /tmp/test.img 100G
><fs> run
><fs> sfdiskM /dev/vda ,
><fs> mkfs ext2 /dev/vda1 # very long pause here ...
><fs> mount /dev/vda1 /
To see the real (ie. allocated) size of the sparse file, use the du
command, eg:
><fs> !du -h /tmp/test.img
1.6G -rw-rw-r-- 1 rjones rjones 100G 2009-11-04 17:40 /tmp/test.img

/bin/sh on Debian is a minimal shell called 'dash' which doesn't
support some features we need such as the particular 'function'
syntax used by regressions/test-stringlist.sh, and therefore
this script was failing on Debian.
Change all of these scripts to use #!/bin/bash explicitly to avoid
these sorts of problems.

Previously when we ran external commands from the daemon, stdin
(ie. fd 0) was closed. This caused a problem when running the
external hexdump command which seems to break if stdin is closed.
This patch opens stdin on /dev/null.

The following 3 summary messages in the configure output
always displayed "yes" even if they were not actually
enabled.
Haskell bindings .................... yes
virt-inspector ...................... yes
virt-* tools ........................ yes
Fixed by correcting the code that tests if the automake
conditional is set.

potential infloop.

This implements FUSE filesystem support so that any libguestfs-
accessible disk image can be mounted as a local filesystem.
Note: file writes (ie. write(2) system call) is not yet implemented.
The API needs more test coverage, particularly lesser-used system
calls.
The big unresolved issue is UID/GID mapping between guest filesystem
IDs and the host. It's not easy to automate this because you need
extra details about the guest itself in order to get to its
UID->username map (eg. /etc/passwd from the guest).
