We weren't using the @FOO@ notation for a Makefile substitution,

Extend the QEMU migration cookie structure to allow information
about the destination host graphics setup to be passed by to
the source host. This will enable seamless migration of any
connected graphics clients

* src/qemu/qemu_migration.c: Add graphics info to migration
  cookies
* daemon/libvirtd.c: Always initialize gnutls to enable
  x509 cert parsing in QEMU

The migration protocol has support for a 'cookie' parameter which
is an opaque array of bytes as far as libvirt is concerned. Drivers
may use this for passing around arbitrary extra data they might
need during migration. The QEMU driver needs to do a few things:

 - Pass hostname/uuid to allow strict protection against localhost
   migration attempts
 - Pass SPICE/VNC server port from the target back to the source to
   allow seamless relocation of client sessions
 - Pass lock driver state from source to destination

This patch introduces the basic glue for handling cookies
but only includes the host/guest UUID & name.

* src/libvirt_private.syms: Export virXMLParseStrHelper
* src/qemu/qemu_migration.c, src/qemu/qemu_migration.h: Parsing
  and formatting of migration cookies
* src/qemu/qemu_driver.c: Pass in cookie parameters where possible
* src/remote/remote_protocol.h, src/remote/remote_protocol.x: Change
  cookie max length to 16384 bytes

This structure will be used to unify lots of duplicated event handling code
across the state drivers.

v2:
    Check for state == NULL in StateFree
    Add NONNULL tagging
    Use bool for isDispatching

Make procedure parsing more robust, by allowing arbitrary
amounts of whitespaces.

Also make some error messages more verbose.

We were 31/73 on whether to translate; since less than 50% translated
and since VIR_INFO is less than VIR_WARN which also doesn't translate,
this makes sense.

These VIR_XXXX0 APIs make us confused, use the non-0-suffix APIs instead.

How do these coversions works? The magic is using the gcc extension of ##.
When __VA_ARGS__ is empty, "##" will swallow the "," in "fmt," to
avoid compile error.

example: origin				after CPP
	high_level_api("%d", a_int)	low_level_api("%d", a_int)
	high_level_api("a  string")	low_level_api("a  string")

About 400 conversions.

8 special conversions:
VIR_XXXX0("") -> VIR_XXXX("msg") (avoid empty format) 2 conversions
VIR_XXXX0(string_literal_with_%) -> VIR_XXXX(%->%%) 0 conversions
VIR_XXXX0(non_string_literal) -> VIR_XXXX("%s", non_string_literal)
  (for security) 6 conversions

Make sure that xgettext scans generated files for translatable
strings, rather than just files stored in libvirt.git.

* .gnulib: Update, for bootstrap and syntax-check fixes.
* bootstrap: Resynchronize with gnulib.
* cfg.mk (generated_files): Define.
* po/POTFILES.in: Add more files with _().

Stop storing the generated files for the remote protocol client

Signed-off-by: NEric Blake <eblake@redhat.com>

Unfortunately, this means that the strings marked for translation
in generated files are not picked up by gnulib's syntax-check,
I'm working on fixing that in gnulib.

* .gitignore, cfg.mk, po/POTFILES.in: Reflect deletion.

In preparation for removing generated files, it is necessary
to tell automake that the generated files must be distributed
but not directly compiled (since they are included into the
body of a larger .c file that is compiled).  Hence, even though
these files are code and not headers in the strict sense of
the word, it is easier to rename them to .h for automake's sake.

Rename remoteSecretListSecrets to remoteListSecrets to match the normal
naming pattern.

This patch just covers the simple functions without explicit return
values. There is more to be handled.

The generator collects the members of the XDR argument structs and uses
this information to generate the function bodies.

Exclude the generated files from offending syntax-checks.

Also mark error messages in block_stats.c for translation, add the
new macro to the msg_gen functions in cfg.mk and add block_stats.c
to po/POTFILES.in

This simplifies several callers that were repeating checks already

Add a new xen driver based on libxenlight [1], which is the primary
toolstack starting with Xen 4.1.0.  The driver is stateful and runs
privileged only.

Like the existing xen-unified driver, the libxenlight driver is
accessed with xen:// URI.  Driver selection is based on the status
of xend.  If xend is running, the libxenlight driver will not load
and xen:// connections are handled by xen-unified.  If xend is not
running *and* the libxenlight driver is available, xen://
connections are deferred to the libxenlight driver.

V6:
 - Address several code style issues noted by Daniel Veillard
 - Make drive work with xen:/// URI
 - Hold domain object reference while domain is injected in
   libvirt event loop.  Race found and fixed by Markus Groß.

V5:
 - Ensure events are unregistered when domain private data
   is destroyed.  Discovered and fixed by Markus Groß.

V4:
 - Handle restart of libvirtd, reconnecting to previously
   started domains
 - Rebased to current master
 - Tested against Xen 4.1 RC7-pre (c/s 22961:c5d121fd35c0)

V3:
  - Reserve vnc port within driver when autoport=yes

V2:
  - Update to Xen 4.1 RC6-pre (c/s 22940:5a4710640f81)
  - Rebased to current master
  - Plug memory leaks found by Stefano Stabellini and valgrind
  - Handle SHUTDOWN_crash domain death event

Commit 7f193757 renamed libvirt-guests.init from .in to .sh, which
made it slip past sc_TAB_in_indentation.  I nearly reintroduced a
tab, so I'm pushing this to prevent that from happening.

* cfg.mk (sc_TAB_in_indentation): Update rule to include .sh files.
* .dir-locals.el: List spacing preference for .sh files.

This is done for two reasons:
- we are getting very close to 64 flags which is the maximum we can use
  with unsigned long long
- by using LL constants in enum we already violates C99 constraint that
  enum values have to fit into int

commit f1fe9671 was supposed to make sure we use files.h

The public object is called NWFilter but the corresponding private
