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

/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.

This adds a new API call guestfs_find0, which is like guestfs_find
but mainly doesn't suffer from the protocol limit of the earlier
command. The earlier command is not deprecated because it is
still very useful.
guestfs_find0 uses a FileOut parameter and writes the results to
an external file. The filenames in the output are separated by
ASCII NUL characters (so a bit like "find -print0").
There is also the addition of a regression test for this command.

This change adds the ability to group entries in a string list with single
quotes. So the string:
"'foo bar'"
becomes 1 token rather than 2. Consequently single quotes must now be escaped:
"\'"
resolves to a literal single quote.
Incidentally, this change also alters another, probably unintentional behaviour
of the previous implementation, in that tokens are separated by any amount of
whitespace rather than a single whitespace character. I.e.:
"a b"
resolves to:
'a' 'b'
rather than:
'a' '' 'b'
That last syntax can be used if an empty argument is still desired. Whitespace
is now also defined to include tabs.
parse_string_list can also now fail if it contains an unmatched open quote.

guestfish --listen necessarily redirects its stdout to /dev/null so as not to
interfere with eval. The remote protocol doesn't contain any other provision for
collecting stdout for the caller, so executing guestfish --remote will never
generate any output.
This patch fixes that by forwarding the caller's STDOUT to the listener over the
unix socket connection. The listener redirects its STDOUT to the caller's STDOUT
for the duration of the command, then closes it again.

'll' command has changed semantics very slightly
(see commit 6727e7c8bdf1cb39264a9de6333d228b51c39956).
We need to fix this test so it doesn't try to run
the ll command without a mounted disk.

This commit implements the RBufferOut type for returning
arbitrary 8 bit data from calls.
We also implement the guestfs_read_file call to read a
whole file that can contain any 8 bit content, but up to
a limit of ~ 2 MB.

The use case is to have a long-running guestfish process in
a shell script, and thus to avoid the overhead of starting
guestfish each time. Do:
eval `guestfish --listen`
guestfish --remote somecmd
guestfish --remote someothercmd
guestfish --remote exit
This patch also supports having multiple guestfish processes
at the same time.
The protocol is simple XDR messages over a Unix domain socket.

Test failure of qemu and recovery of the library:
- mid-command
- between commands
- during launch [test not working yet]
- explicitly killed by guestfs_kill_subprocess
Also this patch cleans up the other tests in this directory
and disables the long-winded test-bootbootboot test.
