inspector: Generate language bindings for OCaml.
This commit adds a generic mechanism for deriving language bindings
for virt-inspector, and implements one concrete binding, for OCaml.
The bindings are generated from the RELAX NG schema (virt-inspector.rng)
which is supposed to be a correct and always up to date description
of the XML that the virt-inspector program can generate.
From the RNG we generate a set of types to describe the output of
virt-inspector for the language, plus an XML parser, plus some
glue code to actually run an external instance of virt-inspector
and parse the resulting XML.
At runtime, an external 'virt-inspector --xml <name>' command runs
and the XML is parsed into language-specific structures.
This has been tested on the four example files (inspector/example?.xml)
The only particular difficulty about the OCaml binding is the use of
Obj.magic, which is naughty but works because of the isomorphism
between the representation of tuples and records in OCaml. This
seems to cause no problems in my test program. Apart from this, the
OCaml binding is straightforward and could be adapted easily for any
other languages that want type-safe virt-inspector bindings.
It's important to keep virt-inspector.rng up to date with changes
to virt-inspector's XML output format.

Implement "null vmchannel" - no vmchannel needed!
This commit removes the requirement for vmchannel, although retaining
support for it.
In this configuration, known as "null vmchannel", the library
listens on a random loopback port. It passes the number of this
port to the appliance (guestfs_vmchannel=tcp:10.0.2.2:12345), and
the daemon then connects back. The library, instead of connecting,
listens and accepts the connection during guestfs_launch.
QEMU SLIRP (user mode networking) is still required to make this
work: SLIRP forwards the TCP connection transparently (instead of
explicitly as with guestfwd) to 127.0.0.1:<port>
There is a window in which any other local process on the machine
could see the port number in the qemu command line and try to
connect to it. This would be a devastating security hole, because
any local process could pretend to be the daemon and feed back
malicious replies to our remote procedure calls. To prevent this,
we check the UID of the other side of the TCP connection. If
the UID is different from the library's EUID, then we reject the
connection. To do this we have to parse /proc/net/tcp. (On Solaris
we could use getsockopt (SO_PEERCRED), but this doesn't work on
Linux TCP sockets).
Other vmchannel(s) are still supported. This is important, because
we can't in general be sure the qemu will always support SLIRP.
In particular, in recent versions of qemu it is possible to compile
out SLIRP.

Set minimum gettext version to 0.17.
This fixes the problem that the 1.0.69 tarball would fail in
the po/ subdirectory when installing:
make[1]: Entering directory `/builddir/build/BUILD/libguestfs-1.0.69/po'
/bin/sh @MKINSTALLDIRS@ /builddir/build/BUILDROOT/libguestfs-1.0.69-1.fc11.x86_64/usr/share
/bin/sh: @MKINSTALLDIRS@: No such file or directory

RHEL 5.3 has gettext 0.14.6. However the tarball will still
build (since it includes all the required code). This may cause
a problem if RHEL users want to build from the git repository.

Remove main loop.
This commit removes the external main loop, which never worked
and caused a number of bugs. Requests are now done synchronously,
and if the user wants to have requests issued in the background
or to have a responsive GUI, then they'll just have to use threads.
The big change is to push all reads and writes through two
functions called send_to_daemon (for writes) and recv_from_daemon
(for reads) which operate synchronously. These functions
read/write whole messages, and also handle checking for EOF
(ie. daemon died) and asynchronous log message events from
qemu (eg. from debug / dmesg printed by the guest). A more
complete description of how these work can be found in the code.
This code passes a complete run of the tests.

guestfish: Enable grouping in string lists
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.

Non-daemon actions indirect through generated code.
Previously non-daemon actions were called directly by
user code, eg:
/* Non-generated */
int
guestfs_set_verbose (guestfs_h *g, int v)
{
g->verbose = !!v;
return 0;
}
This changes these actions so they go indirectly via
some generated code, eg:
/* Generated */
int guestfs_set_verbose (guestfs_h *g,
int verbose)
{
return guestfs__set_verbose (g, verbose);
}
/* Non-generated */
int
guestfs__set_verbose (guestfs_h *g, int v)
{
g->verbose = !!v;
return 0;
}
The aim is to have a place in the generated code where
we can add debug or tracing information for these non-
daemon calls.

guestfish: Redirect stdout when executing remote commands
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.
