We don't have to always extract all files from the OVA archive. The OVA,
as defined in the standard, is plain tar. We can work directly over the
tar archive if we use correct 'offset' and 'size' options when defining
the backing file for QEMU. This puts much lower requirement on available
disk space.
Since the virt-v2v behaviour for OVA input now depends on QEMU version
available this affects some of the tests. Expected result of the
affected also has to depend on the QEMU used thus such tests will have
two *.expected files.

The function looks up file in tar archive and returns a tuple containing
which at byte it starts and how long the file is.

The function returns version of qemu-img as a tuple (major, minor), or
the value (0,9) in case there was an error detecting the version.

In commit 08f82f2e3d we increased the
memory size to 800MB (on x86) so that the semodule command would work.
However it has been discovered that another SELinux command takes
large amounts of RAM (setfiles during the SELinux relabel step).
Therefore increase the memory size again, this time to 2000MB.
The information whether the disk is gzip compressed or not is stored
in the OVF. There is no reason to do the detection.

- Make module name explicit, so it's more obvious which module a
function is defined in.
- Group lines of code by feature.
- Capitalize some module names properly.
Just code motion, no functional change.
Commit 004de6cf45 was not sufficient to
solve this problem. We are also using gperf in guestfish. Rewrite
the code in the same way to avoid having to prototype the hash
function.
Add code in virt-p2v so that it can use nbdkit (with the file plugin)
as an alternative to qemu-nbd.
This is controlled through the virt-p2v --nbd command line option,
allowing you to select which server (out of qemu-nbd or nbdkit) you
prefer (with a fallback). The default is: --nbd=qemu-nbd,nbdkit so
qemu-nbd will be used preferentially.
When testing virt-p2v (eg. on the host machine) this prevents us from
testing two instances of virt-p2v at the same time because both will
try to use the same port.
Generate the random filename using our utility function
guestfs_int_random_string. This also means that we will not need to
call srandom() in guestfish or virt-edit.
The prototype of the hash function changed in gperf 3.1:
* The 'len' parameter of the hash function and of the lookup function is now
of type 'size_t' instead of 'unsigned int'. This makes it safe to call these
functions with strings of length > 4 GB, on 64-bit machines.
This commit moves the guestfs_int_string_to_errno function into the
third (functions) section of the gperf file so it is able to use the
lookup function without needing a prototype.

Three more pieces of common code are moved under the common/
subdirectory. This is just code motion.
Note that windows.[ch] wasn't even being used by guestfish. That code
was only used in other virt tools.
This is mostly code motion but:
(1) I had to remove the compile-time COMPILING_GUESTFISH and
COMPILING_VIRT_RESCUE macros and replace them with runtime constants
and checks.
(2) I moved the fish/config.c file into this library.
Just code motion.
This commit makes it clearer what is a utility and what is part of the
library. It also makes it clear that we should rename:
guestfs-internal-frontend.h -> utils.h
guestfs-internal-frontend-cleanups.h -> cleanups.h (?)
but this commit does not make that change.
This commit, which is just code motion, moves the common XDR protocol
code (libprotocol) and the common errno handling (liberrnostring) into
libraries which are each built once and shared between the library and
daemon.

In the ancient version of PCRE in RHEL 5, partial match support does
not support /.*/, returning PCRE_ERROR_BADPARTIAL. However the
equivalent regular expression /(?:.)*/ works fine, so use that
instead.
RHEL 5 has ancient Gtk 2.10 which lacks several functions and whole
features we need (eg the spinner). Add various macros and function
definitions to work around this.
The guestfs_canonical_device_name API was rewriting /dev/mdX as
/dev/sdX. This is wrong since (eg) /dev/sd0 is not a device name, so
if you pass the canonicalized name back to the API it will fail.
virt-v2v was one tool doing this.
