This patch use file system specific ioctl for getting i_generation

This patch removes redundant shell code and cleans it a little bit.

Shell macro compile_prog takes two arguments:
local_cflags and local ldflags.

$QEMU_CFLAGS is added automatically to the cflags, so there is no need
to pass it as an argument.

It is also unnecessary to pass -Werror twice.

$flag is a compiler warning option, so it should be in local_cflags
instead of local_ldflags.

Enabling the I/O thread by default seems like an important part of declaring
1.0.  Besides allowing true SMP support with KVM, the I/O thread means that the
TCG VCPU doesn't have to multiplex itself with the I/O dispatch routines which
currently requires a (racey) signal based alarm system.

I know there have been concerns about performance.  I think so far the ones that
have come up (virtio-net) are most likely due to secondary reasons like
decreased batching.

I think we ought to force enabling I/O thread early in 1.0 development and
commit to resolving any lingering issues.

This patch tries to cull any uneeded library dependencies from the guest
agent to improve portability across various distros. We do so by being

guest_agent is not supported for mingw32, so the default value
should be 'no', not 'yes'.

This removes the dependencies to glib-2.0 and python which
makes native and cross builds for w32 much easier (no need
to get and install these extra packages).

It also avoids the problems caused by different bitfield alignment
which is required by glib-2.0.

It is still possible to set guest_agent=yes via configure option.

When using xen_enabled() we're currently only checking if xen is enabled
at all during the build. But what if you want to build multiple targets
out of which only one can potentially run xen code?

That means that for generic code we'll still have to fall back to the
variable and potentially slow the code down, but it's not as important as
that is mostly xen device emulation which is not touched for non-xen targets.

The target specific code however can with this patch see that it's unable to
ever execute xen code. We can thus always return 0 on xen_enabled(), giving
gcc enough hints to evict the mapcache code from the target memory management
code.
