Add a "--disable-pygrub" option for being able to disable the build
and installation of pygrub.
There are two main reasons to do so:
- A main reason to use pygrub is to allow a PV guest to choose its
bitness (32- or 64-bit). Pygrub allows that by looking into the boot
image and to start the guest in the correct mode depending on the
kernel selected. With 32-bit PV guests being deprecated and the
possibility to even build a hypervisor without 32-bit PV support,
this use case is gone for at least some configurations.
- Pygrub is running in dom0 with root privileges. As it is operating
on guest controlled data (the boot image) and taking decisions based
on this data, there is a higher security risk. Not being possible
to use pygrub is thus a step towards a reduction of attack surface.
Default is still to build and install pygrub.

This follows the logic used for other decompression methods utilizing an
external library, albeit here we can't ignore the 32-bit size field
appended to the compressed image - its presence causes decompression to
fail. Leverage the field instead to allocate the output buffer in one
go, i.e. without incrementally realloc()ing.
As far as configure.ac goes, I'm pretty sure there is a better (more
"standard") way of using PKG_CHECK_MODULES(). The construct also gets
put next to the other decompression library checks, albeit I think they
all ought to be x86-specific (e.g. placed in the existing case block a
few lines down).
Note that, where possible, instead of #ifdef-ing xen/*.h inclusions,
they get removed.

Access to QMP of QEMU in Linux stubdomain is possible over vchan
connection. Handle the actual vchan connection in a separate process
(vchan-socket-proxy). This simplified integration with QMP (already
quite complex), but also allows preliminary filtering of (potentially
malicious) QMP input.
Since only one client can be connected to vchan server at the same time
and it is not enforced by the libxenvchan itself, additional client-side
locking is needed. It is implicitly implemented by vchan-socket-proxy,
as it handle only one connection at a time. Note that qemu supports only
one simultaneous client on a control socket anyway (but in UNIX socket
case, it enforce it server-side), so it doesn't add any extra
limitation.
libxl qmp client code already has locking to handle concurrent access
attempts to the same qemu qmp interface.

Squash in changes of regenerated autotools files.
Kill the vchan-socket-proxy so we don't leak the daemonized processes.
libxl__stubdomain_is_linux_running() works against the guest_domid, but
the xenstore path is beneath the stubdomain. This leads to the use of
libxl_is_stubdom in addition to libxl__stubdomain_is_linux_running() so
that the stubdomain calls kill for the qmp-proxy.
Also call libxl__qmp_cleanup() to remove the unix sockets used by
vchan-socket-proxy. vchan-socket-proxy only creates qmp-libxl-$domid,
and libxl__qmp_cleanup removes that as well as qmp-libxenstat-$domid.
However, it tolerates ENOENT, and a stray qmp-libxenstat-$domid should
not exist.

The pvshim can only be built 64-bit because the hypervisor is only
64-bit nowadays. The hypervisor build supports XEN_COMPILE_ARCH and
XEN_TARGET_ARCH which override the information from uname. The pvshim
build runs out of the tools/ directory but calls the hypervisor build
system.
If one runs in a Linux 32-bit userland with a 64-bit kernel, one used
to be able to set XEN_COMPILE_ARCH. But nowadays this does not work.
configure sees the target cpu as 64-bit and tries to build pvshim.
The build prints
echo "*** Xen x86/32 target no longer supported!"
and doesn't build anything. Then the subsequent Makefiles try to
install the non-built pieces.
Fix this anomaly by causing configure to honour the Xen hypervisor way
of setting the target architecture.
In principle this user behaviour is not handled quite right, because
configure will still see 64-bit and so all the autoconf-based
architecture testing will see 64-bit rather than 32-bit x86. But the
tools are in fact generally quite portable: this particular location
in configure{.ac,} is the only place in tools/ where 64-bit x86 is
treated differently from 32-bit x86, so the fix is sufficient and
correct for this use case.
It remains the case that XEN_COMPILE_ARCH or XEN_TARGET_ARCH to a
non-x86 architecture, when configure thinks things are x86, or vice
versa, will not work right.
(This is a bugfix to 8845155c83
pvshim: make PV shim build selectable from configure
which inadvertantly deleted the logic to only build the shim for
XEN_TARGET_ARCH != x86_32.)
I have rerun autogen.sh, so this patch contains the fix to configure
as well as the source fix to configure.ac.

* if not absolute, look it up with type -p
* split into directory and executable name

./configure PYTHON=/usr/bin/python
so I assert this has no functional change except that now you can say
